[0003] [Patent Document 1] JP 2019-46876 A Summary of the Invention [Problem to be solved by the invention]

[0004] There is a need to improve the performance of electronic components having a plurality of capacitor sections connected in series inside an element body.

[0005] The present invention has been made to solve such problems, and has an object to provide an electronic component having a plurality of capacitor units connected in series, which can improve performance. [Means for solving the problem]

[0006] The electronic component according to the present invention comprises an element body having a first main surface and a second main surface facing in a first direction, a first end surface and a second end surface facing in a second direction perpendicular to the first direction, and a first side surface and a second side surface facing in a third direction perpendicular to the first direction and the second direction, a first internal electrode provided within the element body and extending to the first main surface which is a mounting surface, a second internal electrode provided within the element body at a position different from the first internal electrode when viewed from the third direction and extended to the first main surface, and a third internal electrode formed on the first main surface and connected to the first internal electrode. The element comprises a first terminal electrode, a second terminal electrode formed on the first end face and connected to the second internal electrode, a third internal electrode provided within the element body and provided at a position opposite the first internal electrode and the second internal electrode in the third direction and extended to the first main surface, and a first external conductor formed on the first main surface and connected to the third internal electrode, wherein the first internal electrode and the third internal electrode are opposed in the third direction to form a first capacitor portion, and the second internal electrode and the third internal electrode are opposed in the third direction to form a second capacitor portion.

[0007] In this electronic component, the first capacitor section and the second capacitor section are connected in series via at least the third internal electrode. By connecting a plurality of capacitor sections in series in this manner, it is possible to reduce short-circuit defects. In addition, the third internal electrode is connected to the first external conductor. Therefore, by connecting the terminal electrode and the external conductor and performing an inspection and measurement, it is possible to inspect the presence or absence of short-circuit defects in the first capacitor section and the second capacitor section. In addition, since the internal electrodes are stacked in a third direction perpendicular to the mounting surface and the terminal electrodes are formed on the first main surface of the mounting surface, it is possible to reduce the ESL. In addition, since there is no variation due to the stacking position of the internal electrodes, it is possible to stabilize the ESR on the high frequency side. As a result, it is possible to improve the performance of an electronic component having a plurality of capacitor sections connected in series.

[0008] The electronic component may include a plurality of first outer conductors, and the first terminal electrode and the second terminal electrode may be disposed between the plurality of first outer conductors. In this case, the distance between the first terminal electrode and the second terminal electrode can be shortened, and therefore, the deflection stress between the terminal electrodes can be reduced when the electronic component is mounted.

[0009] The electronic component may include a plurality of first outer conductors disposed between the first terminal electrode and the second terminal electrode. In this case, by also mounting the outer conductors when mounting the electronic component, it is possible to improve the flexural fixation strength between the terminal electrodes.

[0010] At least one of the first internal electrode, the second internal electrode, and the third internal electrode may have a notch at an outer corner in the second direction on the first main surface side. In this case, even if a crack occurs near a corner of the element body, the crack can be avoided by the notch, thereby preventing the crack from reaching an overlapping portion of the internal electrodes that form the capacitor portion.

[0011] At least one of the first terminal electrode, the second terminal electrode and the first external conductor may be disposed at a corner between the first main surface and the end surface of the element body. In this case, the starting point of a crack can be kept away from the overlapping portion of the internal electrodes, so that even if a crack occurs near a corner of the element body, the crack can be prevented from reaching the overlapping portion of the internal electrodes.

[0012] The electronic component may further include a second outer conductor formed on the first main surface and disposed outward in the second direction from the first terminal electrode, the second terminal electrode, and the first outer conductor. In this case, by mounting the second outer conductor when mounting the electronic component, it is possible to improve the flexural fixation strength between the terminal electrodes.

[0013] The electronic component may include a pair of third internal electrodes, a pair of first external conductors connected to the pair of third internal electrodes, and a fourth internal electrode provided within the body and provided at a position different from the first internal electrodes and the second internal electrodes when viewed from the third direction, where the first internal electrode and one of the third internal electrodes face each other in the third direction to form a first capacitor section, the second internal electrode and the other of the third internal electrodes face each other in the third direction to form a second capacitor section, the fourth internal electrode and one of the third internal electrodes face each other in the third direction to form a third capacitor section, and the fourth internal electrode and the other of the third internal electrodes face each other in the third direction to form a fourth capacitor section. In this case, four capacitor sections can be connected in series via the third internal electrodes and the fourth internal electrodes.

[0014] The electronic component may include a third outer conductor connected to the fourth inner electrode. In this case, the third capacitor unit and the fourth capacitor unit can be inspected for short-circuit defects using the third outer conductor.

[0015] The third outer conductor may be formed on the first main surface, in which case mounting strength can be improved by mounting the third outer conductor when mounting the electronic component.

[0016] The third external conductor may be formed on the second main surface, in which case a large distance can be secured between the terminal electrodes and the external conductors formed on the first main surface. Effect of the Invention

[0019] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the description, the same elements or elements having the same functions will be denoted by the same reference numerals, and duplicated description will be omitted.

[0020] First, the configuration of an electronic component 100 according to this embodiment will be described with reference to Figs. 1 to 3. Fig. 1 is a front view of the electronic component according to this embodiment. Fig. 2(a) is a cross-sectional view taken along line IIa-IIa shown in Fig. 1, and Fig. 2(b) is a cross-sectional view taken along line IIb-IIb shown in Fig. 1. Fig. 3(a) is a diagram showing a first internal electrode and a second internal electrode, Fig. 3(b) is a diagram showing a third internal electrode, and Fig. 3(c) is a diagram showing a state in which the first internal electrode and the second internal electrode overlap with the third internal electrode. In Fig. 3(c), the first internal electrode and the second internal electrode are shown by virtual lines.

[0021] In the following description, an XYZ coordinate system may be set for the electronic component 100. The Z-axis direction (first direction) is a direction perpendicular to the lamination direction in which the internal electrodes described below are laminated. The Z-axis direction is a direction perpendicular to the surface of the circuit board to be mounted when mounted. The X-axis direction (second direction) is a direction perpendicular to the Z-axis direction and parallel to the surface of the circuit board when mounted. The X-axis direction corresponds to the longitudinal direction in which the element body 2 extends. The Y-axis direction (third direction) is a direction perpendicular to the Z-axis direction and the X-axis direction, parallel to the surface of the circuit board when mounted and perpendicular to the X-axis direction. The Y-axis direction is a direction in which the internal electrodes described below are laminated. In FIG. 1, the upper side is the positive side in the Z-axis direction, and the lower side is the negative side in the Z-axis direction.

[0022] As shown in Fig. 1, the electronic component 100 includes an element body 2, a first terminal electrode 3, a second terminal electrode 4, and a pair of external conductors 6A, 6B. As shown in Fig. 2, the electronic component 100 includes a first internal electrode 11, a second internal electrode 12, and a third internal electrode 13 within the element body 2.

[0023] As shown in FIG. 1, the element body 2 is a rectangular parallelepiped component extending along the X-axis direction, which is the longitudinal direction. The element body 2 has a first main surface 2a and a second main surface 2b facing in the Z-axis direction, a first end surface 2c and a second end surface 2d facing in the X-axis direction, and a first side surface 2e and a second side surface 2f facing in the Y-axis direction. The first main surface 2a is disposed on the negative side of the Z-axis direction, and the second main surface 2b is disposed on the positive side of the Z-axis direction. The first end surface 2c is disposed on the negative side of the X-axis direction, and the second end surface 2d is disposed on the positive side of the X-axis direction. The first side surface 2e is disposed on the negative side of the Y-axis direction, and the second side surface 2f is disposed on the positive side of the Y-axis direction. Of these, the first main surface 2a becomes a mounting surface that faces a mounting board when mounted.

[0024] The shape of element body 2 is not particularly limited, but here it has a rectangular parallelepiped shape with the dimension in the X-axis direction greater than the dimensions in the Z-axis direction and the Y-axis direction. The rectangular parallelepiped shape includes a rectangular parallelepiped shape with chamfered corners and ridges, and a rectangular parallelepiped shape with rounded corners and ridges. For example, the length of element body 2 in the X-axis direction may be 1.45 to 3.50 mm, the length in the Y-axis direction may be 0.7 to 1.85 mm, and the length in the Z-axis direction may be 0.7 to 1.85 mm.

[0025] The element body 2 is configured by stacking a plurality of dielectric layers (dielectric layers 5 shown in FIG. 2) in the Y-axis direction. Each dielectric layer is configured, for example, from a sintered ceramic green sheet containing a dielectric material (dielectric ceramic such as BaTiO3-based, Ba(Ti,Zr)O3-based, or (Ba,Ca)TiO3-based). In the actual element body 2, the dielectric layers 5 are integrated to the extent that the boundaries between the dielectric layers 5 are not visible.

[0026] The terminal electrodes 3, 4 are provided on the first main surface 2a of the element body 2. The terminal electrodes 3, 4 are portions for electrically connecting other members to the electronic component 100 and functioning as effective terminals. The terminal electrodes 3, 4 are formed on the first main surface 2a at predetermined positions in the X-axis direction so as to extend in the Y-axis direction (see FIG. 2(a)). The external conductors 6A, 6B are provided on the first main surface 2a of the element body 2. The first external conductors 6A, 6B improve the fixing strength with other members and function as terminals for measuring electrical characteristics. The first external terminals 6A, 6B are formed on the first main surface 2a at predetermined positions in the X-axis direction so as to extend in the Y-axis direction. In this embodiment, the first external terminal 6A, the first terminal electrode, the second terminal electrode, and the first external terminal electrode 6B are provided in this order from the negative side to the positive side in the X-axis direction. As a result, the first terminal electrode 3 and the second terminal electrode 4 are disposed between the plurality of first outer conductors 6A, 6B.

[0027] As shown in FIG. 2, the internal electrodes 11, 12, and 13 are flat conductor patterns extending parallel to the XZ plane. A plurality of the internal electrodes 11, 12, and 13 are formed in the Y-axis direction. The first internal electrode 11 is provided in a negative region in the X-axis direction in the element body 2, and is connected to the first terminal electrode 3 at the first main surface 2a. The second internal electrode 12 is provided in a positive region in the X-axis direction in the element body 2, and is connected to the second terminal electrode 4 at the first main surface 2a. The second internal electrode 12 is provided at a position different from that of the first internal electrode 11 when viewed from the Y-axis direction. The first internal electrode 11 and the second internal electrode 12 are arranged in the same plane. That is, the first internal electrode 11 and the second internal electrode 12 are formed on the same dielectric layer 5, and are at the same position in the Y-axis direction. Before lamination, the conductor patterns of the first internal electrode 11 and the second internal electrode 12 are formed on the ceramic green sheets of the dielectric layer 5.

[0028] The third internal electrode 13 is provided in both negative and positive regions in the X-axis direction in the element body 2, and is extended to the first main surface 2a. The third internal electrode 13 is disposed on a different surface from the internal electrodes 11, 12. That is, the third internal electrode 13 is formed on a different dielectric layer 5 from the internal electrodes 11, 12, and is at a different position in the Z-axis direction. Before lamination, the conductor pattern of the third internal electrode 13 is formed on the ceramic green sheet of the dielectric layer 5.

[0029] An example of a specific shape of each of the internal electrodes 11, 12, and 13 will be described with reference to FIG. 3. In the following description, a center line CL in the X-axis direction set for the element body 2 may be used for the description. As shown in FIG. 3(a), the first internal electrode 11 and the second internal electrode 12 are symmetrical with respect to each other with respect to the center line CL. The first internal electrode 11 is formed in an area on the negative side of the center line CL in the X-axis direction. The first internal electrode 11 includes a main body portion 21 and a lead portion 22. The main body portion 21 has a rectangular outer shape. The four edges of the main body portion 21 are arranged so as to be spaced apart from the first main surface 2a, the second main surface 2b, the first end surface 2c, and the center line CL. The lead portion 22 extends from an end portion on the inner side (positive side) in the X-axis direction of the main body portion 21 to the negative side in the Z-axis direction and is exposed at the first main surface 2a, whereby it is connected to the first terminal electrode 3.

[0030] The second internal electrode 12 is formed in a region on the positive side in the X-axis direction from the center line CL. The second internal electrode 12 includes a main body 23 and an extraction portion 24. The main body 23 has a rectangular outer shape. The four edges of the main body 23 are arranged so as to be spaced apart from the first main surface 2a, the second main surface 2b, the second end surface 2d, and the center line CL. The extraction portion 24 extends from an end portion on the inner side (negative side) in the X-axis direction of the main body 23 to the negative side in the Z-axis direction and is exposed on the first main surface 2a, thereby being connected to the second terminal electrode 4. A gap is formed between the first internal electrode 11 and the second internal electrode 12 at a position including the center line CL.

[0031] As shown in FIG. 3(b), the third internal electrode 13 has a configuration that is line-symmetrical with respect to the center line CL. The third internal electrode 13 includes a main body 26 and a pair of lead portions 27A, 27B. The main body 26 extends to both the negative side and the positive side in the X-axis direction with respect to the center line CL. When viewed from the Z-axis direction, the main body 26 has an outer shape similar to that of the main body 21 of the first internal electrode 11 on the negative side in the X-axis direction, and has an outer shape similar to that of the main body 23 of the second internal electrode 12 on the positive side in the X-axis direction, and has a shape that connects a portion corresponding to the main body 21 and a portion corresponding to the main body 23 (see FIG. 3(c)). The main body 26 is disposed so as to face both the main body portions 21, 23 in the Z-axis direction. The lead portion 27A extends from an end portion on the outer side (negative side) of the main body 26 in the X-axis direction to the negative side in the Z-axis direction and is exposed on the first main surface 2a, thereby being connected to the external conductor 6A. The lead portion 27B extends from the outer (positive side) end of the main body portion 26 in the X-axis direction to the negative side in the Z-axis direction and is exposed on the first main surface 2a, thereby being connected to the external conductor 6B.

[0032] As a result, as shown in FIG. 2(b), inside the element body 2, a first capacitor section 10A is formed in a region on the negative side in the X-axis direction, and a second capacitor section 10B is formed in a region on the positive side in the X-axis direction. The first capacitor section 10A is formed by the first internal electrode 11 and the third internal electrode facing each other in the Y-axis direction. The first capacitor section 10A is formed by alternately stacking a plurality of first internal electrodes 11 and a plurality of third internal electrodes 13. The second capacitor section 10B is formed by alternately stacking a plurality of second internal electrodes 12 and a plurality of third internal electrodes 13. The second capacitor section 10B is formed by the second internal electrode 12 and the third internal electrode facing each other in the Y-axis direction. The first capacitor section 10A and the second capacitor section 10B are connected in series by the main body 26 of the third internal electrode.

[0033] 2, the first internal electrode 11 and the second internal electrode 12 are arranged in the outermost layer of the laminated internal electrodes. That is, among the internal electrodes arranged inside the element body 2, the first internal electrode 11 and the second internal electrode 12 are arranged furthest on the positive side in the Y-axis direction, and the first internal electrode 11 and the second internal electrode 12 are arranged furthest on the negative side in the Y-axis direction.

[0034] Next, the functions and effects of electronic component 100 according to this embodiment will be described.

[0035] In the electronic component 100, the first capacitor section 10A and the second capacitor section 10B are connected in series via at least the third internal electrode 13. In this case, even if one of the capacitor sections 10A, 10B is damaged, the capacitor function of the other remains, so that short-circuit defects can be reduced. By connecting a plurality of capacitor sections 10A, 10B in series in this manner, short-circuit defects can be reduced. In addition, the third internal electrode 13 is connected to the first external conductors 6A, 6B. Therefore, the presence or absence of short-circuit defects in the first capacitor section 10A and the second capacitor section 10B can be inspected by connecting the terminal electrodes 3, 4 and the external conductors 6A, 6B and inspecting and measuring them.

[0036] Here, an electronic component 200 according to a comparative example will be described with reference to FIG. 4. In the electronic component 200 according to the comparative example, the internal electrodes are stacked in the Z-axis direction perpendicular to the mounting surface, and the terminal electrodes 203, 204 are formed on the end faces 2c, 2d perpendicular to the mounting surface. In this case, when the electronic component 200 is mounted on a board with the first main surface 2a as the mounting surface, the current path L1 passing through the negative internal electrode in the Z-axis direction, which is the stacking direction, and the current path L2 passing through the positive internal electrode are not equivalent circuits, so that the high-frequency side ESR of the electronic component 200 becomes unstable. In addition, when the terminal electrode 203 is connected to the electrode PD on the board side via the solder part BD, the solder part BD extends to a high position in the Z-axis direction, so that the crack CR generated by the bending stress becomes large and may reach the overlapping part of the internal electrodes 11, 13 in the capacitor part 10A.

[0037] In contrast, in electronic component 100 according to this embodiment, the internal electrodes are stacked in the Y-axis direction perpendicular to the mounting surface, and terminal electrodes 3, 4 are formed on first main surface 2a, which is the mounting surface, so that the ESL can be reduced. In addition, since there is no variation due to the stacking position of the internal electrodes, the ESR on the high frequency side can be stabilized. As a result, the performance of electronic component 100 having multiple capacitor sections 10A, 10B connected in series can be improved.

[0038] Moreover, since the terminal electrodes 3, 4 are formed on the first main surface 2a, which is the mounting surface, when the first terminal electrode 3 is connected to the electrode PD on the board side via the solder part BD, there is no need to raise the solder part BD significantly in the Z-axis direction. This makes it possible to prevent the cracks CR from reaching the overlapping part of the internal electrodes 11, 13 (see FIG. 2(a)). Furthermore, since the terminal electrodes 203, 204 are formed on the end faces 2c, 2d of the electronic component 200 according to the comparative example, the dimension in the X-axis direction is large, and the mounting area is therefore large. On the other hand, since the terminal electrodes 3, 4 are formed on the mounting surface of the electronic component 100 of this embodiment, the mounting area can be reduced.

[0039] The electronic component 100 includes a plurality of first outer conductors 6A, 6B, and the first terminal electrode 3 and the second terminal electrode 4 are disposed between the plurality of first outer conductors 6A, 6B. In this case, the distance between the first terminal electrode 3 and the second terminal electrode 4 can be shortened, and therefore the deflection stress between the terminal electrodes 3, 4 can be reduced when the electronic component 100 is mounted. For example, in the electronic component 200 according to the comparative example shown in FIG. 4, the terminal electrodes 3 and 4 are formed at both ends in the X-axis direction, and therefore the dimension between them is large. Therefore, the stress when deflection occurs between the terminal electrodes 3, 4 is large.

[0040] The present invention is not limited to the above-described embodiments.

[0041] The structure of the internal electrodes of the electronic component 100 is not limited to the above-described embodiment. For example, the structure shown in Fig. 5 may be adopted. The electronic component 100 shown in Fig. 5 includes a plurality of first outer conductors 6A, 6B, which may be disposed between the first terminal electrode 3 and the second terminal electrode 4. In this case, by also mounting the first outer conductors 6A, 6B when mounting the electronic component 100, the flexure fixing strength between the terminal electrodes 3, 4 can be improved.

[0042] Specifically, as shown in Fig. 5(a), the first terminal electrode 3, the first outer conductor 6A, the first outer conductor 6B, and the second terminal electrode 4 are provided in this order from the negative side to the positive side in the X-axis direction. The lead portion 22 of the first inner electrode 11 is provided at the end of the main body portion 21 on the negative side in the X-axis direction. The lead portion 24 of the second inner electrode 12 is provided at the end of the main body portion 23 on the positive side in the X-axis direction. Furthermore, as shown in Fig. 5(b), the lead portions 6A and 6B are provided near the center line CL of the third inner electrode 13.

[0043] As shown in FIG. 6(a), the main body 21 of the first internal electrode 11 may have a notch 31A at a corner on the outer side (negative side) in the X-axis direction on the first main surface 2a side, and the main body 23 of the second internal electrode 12 may have a notch 31B at a corner on the outer side (positive side) in the X-axis direction on the first main surface 2a side. In this case, even if a crack occurs near the corners CR1 and CR2 of the element body 2, the crack can be prevented from reaching the overlapping portion of the internal electrodes forming the capacitor sections 10A and 10B by avoiding the crack at the notches 31A and 31B. The configuration of the notches as shown in FIG. 6(a) may be applied to the configuration of FIG. 5. In this case, the corner of the main body 26 of the third internal electrode 13 on the first main surface 2a side has a notch.

[0044] As shown in FIG. 6(b), the first external conductors 6A and 6B may be disposed at the corners CR1 and CR2 between the first main surface 2a and the end surfaces 2c and 2d of the element body 2. In this case, the first external conductors 6A and 6B, which are the starting points of the cracks, can be kept away from the overlapping portions of the internal electrodes. Therefore, even if a crack occurs near the corners CR1 and CR2 of the element body 2, the cracks can be prevented from reaching the overlapping portions of the internal electrodes. In this case, the lead portions 27A and 27B of the third internal electrode 13 extend so as to incline toward the corners CR1 and CR2. The configuration shown in FIG. 6(b) may be applied to the configuration of FIG. 5. In this case, the first terminal electrode 3 and the second terminal electrode 4 are disposed at the corners CR1 and CR2, and the lead portions 22 and 24 extend so as to incline toward the corners CR1 and CR2.

[0045] For example, a structure shown in Fig. 7 may be adopted. As shown in Fig. 7, the electronic component 100 includes a pair of third internal electrodes 13A, 13B, a pair of first external conductors 6A, 6B connected to the pair of third internal electrodes 13A, 13B, and a fourth internal electrode 14 provided in the element body 2 at a position different from the first internal electrode 11 and the second internal electrode 12 when viewed from the Y-axis direction. As shown in Fig. 7(c), the first capacitor section 10A may be configured by the first internal electrode 11 and one third internal electrode 13A facing each other in the Y-axis direction, the second capacitor section 10B may be configured by the second internal electrode 12 and the other third internal electrode 13B facing each other in the Y-axis direction, the third capacitor section 10C may be configured by the fourth internal electrode 14 and one third internal electrode 13A facing each other in the Y-axis direction, and the fourth capacitor section 10D may be configured by the fourth internal electrode 14 and the other third internal electrode 13 facing each other in the Y-axis direction. In this case, the four capacitor sections 10A, 10C, 10D, and 10B can be connected in series via the third inner electrodes 13A, 13B and the fourth inner electrode .

[0046] As shown in FIG. 7(a), the fourth internal electrode 14 is provided at a position spaced away from the first internal electrode 11 and the second internal electrode 12 on the positive side in the Z-axis direction. The fourth internal electrode 14 has a rectangular main body 28 and an extraction portion 29. The main body 28 is formed so as to extend to both positive and negative regions in the X-axis direction with respect to the center line CL. The extraction portion 29 is extracted from the main body 28 to the positive side in the Z-axis direction and is exposed at the second main surface 2b. The extraction portion 29 is connected to the third external conductor 7 formed on the second main surface 2b.

[0047] As shown in FIG. 7(b), a pair of third internal electrodes 13A, 13B are formed by dividing one internal electrode 13 shown in FIG. 3(b) at the position of the center line CL. One third internal electrode 13A is formed in a region on the negative side in the X-axis direction from the center line CL. The main body portion 26A of one third internal electrode 13A faces the first internal electrode 11 in a region on the negative side in the Z-axis direction, and faces the fourth internal electrode 14 in a region on the positive side in the Z-axis direction. The other third internal electrode 13B is formed in a region on the positive side in the X-axis direction from the center line CL.
