Description

[Technical field]

[0001] The present invention relates to electronic components. [Background technology]

[0002] Patent Document 1 discloses an electronic component in a laminated bandpass filter that is a laminate of multiple dielectric layers and multiple electrode layers, the electronic component including a ground electrode formed on one of the electrode layers, a capacitor electrode formed on one of the electrode layers, and an inductor electrode consisting of a line electrode formed on one of the electrode layers and a via electrode formed in a dielectric layer.

[0003] [Patent Document 1] JP 2012-23752 A Summary of the Invention [Problem to be solved by the invention]

[0004] In electronic components, the inductance of an inductor and the capacitance of a capacitor are set to obtain desired characteristics. In electronic components, the capacitance of a capacitor is formed by a plurality of capacitor conductors (capacitor electrodes). When forming capacitance by capacitor conductors, it is difficult to set a minute capacitance, and therefore it is difficult to fine-tune the capacitance. As a result, there are cases where the desired characteristics cannot be obtained.

[0005] An object of one aspect of the present disclosure is to provide an electronic component that can achieve desired characteristics. [Means for solving the problem]

[0006] (1) An electronic component according to one aspect of the present invention comprises a base body, an inductor disposed within the base body, the inductor having first and second conductors extending in one direction and a connecting conductor connecting the first and second conductors, and a capacitor conductor disposed within the base body and connected to the first conductor of the inductor, wherein when viewed from the one direction, the width of the capacitor conductor is equal to or less than the widths of the first and second conductors, and the capacitor conductor extends in a direction perpendicular to the one direction when viewed from the one direction and is disposed in the vicinity of the second conductor.

[0007] In an electronic component according to an aspect of the present invention, a capacitor conductor is connected to a first conductor of an inductor. In this configuration, the capacitor conductor extends in a direction perpendicular to the one direction when viewed from one direction, and is disposed in the vicinity of the second conductor. In this configuration, a capacitance is formed by the second conductor of the inductor and the capacitor conductor due to electric field coupling between the second conductor of the inductor and the capacitor conductor. In this way, in the electronic component, a capacitance is formed by the second conductor of the inductor and the capacitor conductor, so that a smaller capacitance can be formed compared to a case where a capacitance is formed by a plurality of capacitor conductors. In addition, in the electronic component, the width of the capacitor conductor is equal to or smaller than the width of each of the first conductor and the second conductor. In this configuration, the area of ​​the capacitor conductor is small, so that it is possible to suppress the formation of a capacitance between the capacitor conductor and other conductors (conductors other than the second conductor). Therefore, in the electronic component, it is possible to set the capacitance according to the design. Therefore, the electronic component can obtain desired characteristics.

[0008] (2) The electronic component of (1) above may include a ground conductor disposed within the element body, and the first conductor and the second conductor may not be electrically connected to the ground conductor. In this configuration, the inductor is not grounded, and a 1 / 2λ resonator is formed by the inductor and the capacitor conductor. In this case, the voltages at the ends of the first conductor and the second conductor become large. When the capacitor conductor is disposed near the end of the second conductor, the electric field coupling between the capacitor conductor and the second conductor can be well adjusted.

[0009] (3) In the electronic component of (1) or (2) above, the element body may have a mounting surface on which the terminal electrodes are arranged and a main surface facing the mounting surface in one direction, and an end of the second conductor near the capacitor conductor may be located closer to the main surface than the capacitor conductor. In this configuration, the capacitor conductor and the end of the second conductor are located apart from each other in the opposing direction (one direction) between the mounting surface and the main surface. This allows for good formation of capacitance between the capacitor conductor and the second conductor.

[0010] (4) In any one of the electronic components (1) to (3) above, the capacitor conductor and the second conductor do not have to overlap when viewed from one direction. In this configuration, the capacitance formed by the capacitor conductor and the second conductor can be reduced. Therefore, a very small capacitance can be formed. Effect of the Invention

[0011] According to one aspect of the present invention, desired characteristics can be obtained. [Brief description of the drawings]

[0013] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicated explanations will be omitted.

[0014] The configuration of an electronic component according to one embodiment will be described with reference to Fig. 1(a) and Fig. 1(b). Fig. 1(a) and Fig. 1(b) are perspective views of the electronic component. As shown in Fig. 1(a) and Fig. 1(b), the electronic component 1 includes an element body 2, a first terminal electrode 3, a second terminal electrode 4, a third terminal electrode 5, a fourth terminal electrode 6, a fifth terminal electrode 7, and a sixth terminal electrode 8, and a resonator 9.

[0015] The element body 2 has a rectangular parallelepiped shape. The rectangular parallelepiped shape includes a rectangular parallelepiped shape with chamfered corners and ridges, and a rectangular parallelepiped shape with rounded corners and ridges. The element body 2 has, as outer surfaces, a pair of end faces 2a, 2b, a pair of main faces 2c, 2d, and a pair of side faces 2e, 2f. The end faces 2a, 2b face each other. The main faces 2c, 2d face each other. The side faces 2e, 2f face each other. In the following, the facing direction of the end faces 2a, 2b is a first direction D1, the facing direction of the main faces 2c, 2d is a second direction (one direction) D2, and the facing direction of the side faces 2e, 2f is a third direction D3. The first direction D1, the second direction D2, and the third direction D3 are approximately perpendicular to each other.

[0016] The end faces 2a, 2b extend in the second direction D2 to connect the main faces 2c, 2d. The end faces 2a, 2b also extend in the third direction D3 to connect the side faces 2e, 2f. The main faces 2c, 2d extend in the first direction D1 to connect the end faces 2a, 2b. The main faces 2c, 2d also extend in the third direction D3 to connect the side faces 2e, 2f. The side faces 2e, 2f extend in the first direction D1 to connect the end faces 2a, 2b. The side faces 2e, 2f also extend in the second direction D2 to connect the main faces 2c, 2d.

[0017] The main surface 2d is a mounting surface, and is the surface that faces another electronic device (not shown) when the electronic component 1 is mounted on another electronic device (for example, a circuit board or a multilayer electronic component). The end surfaces 2a and 2b are surfaces that continue from the mounting surface (i.e., the main surface 2d). The main surface 2c is provided with a mark M. The mark M indicates the orientation of the electronic component 1. It is noted that the mark M does not necessarily have to be provided.

[0018] The length of the element body 2 in the first direction D1 is longer than the length of the element body 2 in the second direction D2 and the length of the element body 2 in the third direction D3. The length of the element body 2 in the second direction D2 is shorter than the length of the element body 2 in the third direction D3. That is, in this embodiment, the end faces 2a, 2b, the main faces 2c, 2d and the side faces 2e, 2f have a rectangular shape. The length of the element body 2 in the second direction D2 may be equal to the length of the element body 2 in the third direction D3 or may be longer than the length of the element body 2 in the third direction D3.

[0019] In this embodiment, "equivalent" may mean not only equal but also values ​​including slight differences or manufacturing errors within a preset range. For example, if multiple values ​​are within a range of ±5% of the average value of the multiple values, the multiple values ​​are defined as equivalent.

[0020] The element body 2 is formed by stacking multiple insulator layers (not shown) in the second direction D2. That is, the stacking direction of the element body 2 is the second direction D2. In the actual element body 2, the multiple insulator layers may be integrated to the extent that the boundaries between the layers are not visible, or may be integrated so that the boundaries between the layers are visible.

[0021] The insulating layer is formed of, for example, a sintered ceramic green sheet containing a dielectric material, for example, at least one selected from a BaTiO3-based material, a Ba(Ti,Zr)O3-based material, a (Ba,Ca)TiO3-based material, a glass material, and an alumina material.

[0022] The first terminal electrode 3, the second terminal electrode 4, the third terminal electrode 5, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 are each provided on the element body 2. The first terminal electrode 3, the second terminal electrode 4, the third terminal electrode 5, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 are each arranged on the main surface 2d of the element body 2. The first terminal electrode 3, the second terminal electrode 4, and the third terminal electrode 5 are arranged in a position closer to the side surface 2e. The fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 are arranged in a position closer to the side surface 2f.

[0023] The first terminal electrode 3 is located on the end surface 2a side, and the third terminal electrode 5 is located on the end surface 2b side. The second terminal electrode 4 is located between the first terminal electrode 3 and the third terminal electrode 5 in the first direction D1. The fourth terminal electrode 6 is located on the end surface 2a side, and the sixth terminal electrode 8 is located on the end surface 2b side. The fifth terminal electrode 7 is located between the fourth terminal electrode 6 and the sixth terminal electrode 8 in the first direction D1. The first terminal electrode 3 and the fourth terminal electrode 6 are arranged opposite to each other in the third direction D3. The second terminal electrode 4 and the fifth terminal electrode 7 are arranged opposite to each other in the third direction D3. The third terminal electrode 5 and the sixth terminal electrode 8 are arranged opposite to each other in the third direction D3.

[0024] Each of the first terminal electrode 3, the second terminal electrode 4, the third terminal electrode 5, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 has a rectangular shape (rectangular shape). Each of the first terminal electrode 3, the second terminal electrode 4, the third terminal electrode 5, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 is arranged so that each side is along the first direction D1 or the third direction D3. The first terminal electrode 3, the second terminal electrode 4, the third terminal electrode 5, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 protrude from the main surface 2d. That is, in this embodiment, each surface of the first terminal electrode 3, the second terminal electrode 4, the third terminal electrode 5, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 is not flush with the main surface 2d. The first terminal electrode 3, the second terminal electrode 4, the third terminal electrode 5, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 are made of a conductive material (for example, Cu).

[0025] Each of the first terminal electrode 3, the second terminal electrode 4, the third terminal electrode 5, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 may be provided with a plating layer (not shown) containing, for example, Ni, Sn, Au, etc. by electrolytic plating or electroless plating. The plating layer may have, for example, a Ni plating film containing Ni and covering the first terminal electrode 3, the second terminal electrode 4, the third terminal electrode 5, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8, and an Au plating film containing Au and covering the Ni plating film.

[0026] 2, 3, 4, and 5 are perspective views showing a resonator 9. The element body 2 is not shown in Figs. 2 to 5. The resonator 9 is disposed within the element body 2. The resonator 9 is configured to include an inductor 10, an inductor 11, a ground conductor 12, a capacitor conductor 13, a capacitor conductor 14, a capacitor conductor 15, a capacitor conductor 16, a capacitor conductor 17, a capacitor conductor 19, a capacitor conductor 20, and a capacitor conductor 21.

[0027] The inductor 10 includes a first conductor 10A, a second conductor 10B, and a connecting conductor 10C. In this embodiment, the inductor 10 includes two connecting conductors 10C.

[0028] The first conductor 10A extends along the second direction D2 (one direction). The first conductor 10A may be composed of a plurality of via conductors. The second conductor 10B extends along the second direction D2. The second conductor 10B may be composed of a plurality of via conductors. The first conductor 10A and the second conductor 10B are arranged at a predetermined interval in the first direction D1.

[0029] The connection conductor 10C electrically connects the first conductor 10A and the second conductor 10B. The connection conductor 10C has a channel shape (approximately U-shaped or C-shaped). The connection conductor 10C connects one end of the first conductor 10A in the second direction D2 (the end on the main surface 2c side) and one end of the second conductor 10B in the second direction D2 (the end on the main surface 2c side). The connection conductor 10C spans the first conductor 10A and the second conductor 10B. The two connection conductors 10C are arranged opposite each other in the second direction D2.

[0030] The inductor 11 includes a first conductor 11A, a second conductor 11B, a third conductor 11C, and a connecting conductor 11D. In this embodiment, the inductor 11 includes two connecting conductors 11D.

[0031] The first conductor 11A extends along the second direction D2. The first conductor 11A may be composed of a plurality of via conductors. The second conductor 11B extends along the second direction D2. The second conductor 11B may be composed of a plurality of via conductors. The third conductor 11C extends along the second direction D2. The third conductor 11C may be composed of a plurality of via conductors. The first conductor 11A and the second conductor 11B are arranged at a predetermined interval in the third direction D3. The second conductor 11B and the third conductor 11C are arranged at a predetermined interval in the first direction D1.

[0032] The connection conductor 11D electrically connects the first conductor 11A, the second conductor 11B, and the third conductor 11C. The connection conductor 11D has a substantially L-shape. The connection conductor 11D connects one end of the first conductor 11A in the second direction D2 (the end on the main surface 2c side), one end of the second conductor 11B in the second direction D2 (the end on the main surface 2c side), and one end of the third conductor 11C in the second direction D2 (the end on the main surface 2c side). The three connection conductors 11D are arranged opposite each other in the second direction D2.

[0033] The second conductor 10B of the inductor 10 and the first conductor 11A of the inductor 11 are electrically connected by a connecting conductor 22.

[0034] The ground conductor 12 is electrically connected to the second terminal electrode 4 and the sixth terminal electrode 8. The ground conductor 12 is connected to the second terminal electrode 4 by a connecting conductor 23. The ground conductor 12 is connected to the sixth terminal electrode 8 by a connecting conductor 24. The ground conductor 12 is not electrically connected to the inductor 10 and the inductor 11. In other words, the ground conductor 12 is not electrically connected to the first conductor 10A, the second conductor 10B, the first conductor 11A, the second conductor 11B, and the third conductor 11C.

[0035] The capacitor conductor 13 is connected to an end (the end on the principal surface 2d side) of the first conductor 10A of the inductor 10. The capacitor conductor 14 is connected to an end (the end on the principal surface 2d side) of the first conductor 10A of the inductor 10.

[0036] The capacitor conductor 16 and the capacitor conductor 18 are connected to the first conductor 11A of the inductor 11. The capacitor conductor 15 is connected to the capacitor conductor 18. The capacitor conductor 15 is electrically connected to the first conductor 11A via the capacitor conductor 18. The capacitor conductor 19 is connected to the third conductor 11C of the inductor 11. The capacitor conductor 20 is connected to the first conductor 11A and the second conductor 11B of the inductor 11. The capacitor conductor 21 is connected to the second conductor 10B of the inductor 10.

[0037] The capacitor conductor 17 is connected to the first conductor 10A of the inductor 10. The capacitor conductor 17 is connected to an end of the first conductor 10A in the second direction D2 (an end on the main surface 2d side). The capacitor conductor 17 has a rectangular (long) shape. One end of the capacitor conductor 17 in the extending direction is connected to the first conductor 10A. The capacitor conductor 17 extends along the first direction D1. That is, the capacitor conductor 17 extends in a direction perpendicular to the second direction D2 when viewed from the second direction D2.

[0038] As shown in FIG. 6, the width W1 of the capacitor conductor 17 is equal to or smaller than the width W2 of the first conductor 10A (W1≦W2). The width W1 of the capacitor conductor 17 is equal to or smaller than the width W3 of the second conductor 10B (W1≦W3). The width W1 of the capacitor conductor 17 is the width of the capacitor conductor 17 when viewed from the second direction D2. The width W1 of the capacitor conductor 17 is the maximum width. The width W2 of the first conductor 10A is the maximum width (maximum diameter) of the first conductor 10A. The width W3 of the second conductor 10B is the maximum width (maximum diameter) of the second conductor 10B. When viewed from the second direction D2, the capacitor conductor 17 does not overlap with the second conductor 10B of the inductor 10.

[0039] 7, the capacitor conductor 17 is disposed at a position closer to the principal surface 2d than the end of the second conductor 10B of the inductor 10 on the principal surface 2d side. In other words, the end of the second conductor 10B of the inductor 10 is disposed at a position closer to the principal surface 2c than the capacitor conductor 17.

[0040] The capacitor conductor 17 is disposed near the second conductor 10B. Specifically, the tip end of the capacitor conductor 17 (the end opposite to the base end connected to the first conductor 10A) is disposed near the second conductor 10B of the inductor 10. The vicinity is a distance at which the capacitor conductor 17 and the second conductor 10B are electrically coupled. The vicinity can also be said to be a distance at which the capacitor conductor 17 and the second conductor 10B form a capacitance. As shown in FIG. 8, the distance Z between the capacitor conductor 17 and the second conductor 10B can be determined by the distance X between the capacitor conductor 17 and the second conductor 10B in the second direction D2 and the distance Y between the capacitor conductor 17 and the second conductor 10B in the third direction D3. The distance X can be set by the thickness of the dielectric layer. The distance Z is, for example, 66 μm or more and 180 μm or less.

[0041] As described above, in the electronic component 1 according to the present embodiment, the capacitor conductor 17 is connected to the first conductor 10A of the inductor 10. In this configuration, the capacitor conductor 17 extends in a direction perpendicular to the second direction D2 (the extension direction of the first conductor 10A) when viewed from the second direction D2, and is disposed in the vicinity of the second conductor 10B. In this configuration, a capacitance is formed by the second conductor 10B of the inductor 10 and the capacitor conductor 17 due to electric field coupling between the second conductor 10B of the inductor 10 and the capacitor conductor 17. In this manner, in the electronic component 1, a capacitance is formed by the second conductor 10B of the inductor 10 and the capacitor conductor 17, so that a smaller capacitance can be formed compared to a case where a capacitance is formed by a plurality of capacitor conductors. In addition, in the electronic component 1, the width W1 of the capacitor conductor 17 is equal to or smaller than the widths W2 and W3 of the first conductor 10A and the second conductor 10B. In this configuration, the area of ​​the capacitor conductor 17 is small, so that it is possible to suppress the formation of a capacitance between the capacitor conductor 17 and another conductor (a conductor other than the second conductor 10B). Therefore, it is possible to set the capacitance according to the design in the electronic component 1. Therefore, the electronic component 1 can obtain desired characteristics.

[0042] FIG. 9 is a diagram showing the frequency characteristics of the electronic component 1. In FIG. 9, the horizontal axis indicates frequency (GHz), and the vertical axis indicates the S21 parameter (dB). In FIG. 9, the solid line indicates the characteristics when the electric field coupling between the capacitor conductor 17 and the second conductor 10B is in a first state, the dashed line indicates the characteristics when the electric field coupling between the capacitor conductor 17 and the second conductor 10B is in a second state, and the dashed line indicates the characteristics when the electric field coupling between the capacitor conductor 17 and the second conductor 10B is in a third state. The electric field coupling in the second state is weaker than that in the first state, and the electric field coupling in the third state is stronger than that in the first state. As shown in FIG. 9, in the electronic component 1, a predetermined characteristic can be obtained by adjusting the electric field coupling between the capacitor conductor 17 and the second conductor 10B.

[0043] In the electronic component 1 according to this embodiment, the resonator 9 includes a ground conductor 12 disposed within the element body 2. In the electronic component 1, the first conductor 10A and the second conductor 10B of the inductor 10 are not electrically connected to the ground conductor 12. In this configuration, the inductor 10 is not grounded, and therefore a 1 / 2λ resonator 9 is formed. In this case, the voltages at the ends of the first conductor 10A and the second conductor 10B become large. In a configuration in which the capacitor conductor 17 is disposed near the end of the second conductor 10B, the electric field coupling between the capacitor conductor 17 and the second conductor 10B can be well adjusted.

[0044] In the electronic component 1 according to this embodiment, an end of the second conductor 10B of the inductor 10 near the capacitor conductor 17 is located closer to the main surface 2c than the capacitor conductor 17. In this configuration, the capacitor conductor 17 and the end of the second conductor 10B are located apart from each other in the second direction D2. This allows good capacitance to be formed between the capacitor conductor 17 and the second conductor 10B.

[0045] In the electronic component 1 according to this embodiment, the capacitor conductor 17 and the second conductor 10B do not overlap when viewed from the second direction D2. With this configuration, the capacitance formed by the capacitor conductor 17 and the second conductor 10B can be reduced. Therefore, a very small capacitance can be formed.

[0046] 8, when the distance X is determined by the thickness of the dielectric layer, the distance X is unlikely to change. In this configuration, when a shift occurs between the dielectric layers stacked in the second direction D2, the distance Y changes. However, the shift is much smaller than the thickness (distance X) of the dielectric layer. Therefore, in the electronic component 1, the change (fluctuation) in the distance Z can be suppressed, and therefore the occurrence of variations in characteristics can be suppressed.

[0047] Although the embodiment of the present invention has been described above, the present invention is not necessarily limited to the above-described embodiment, and various modifications are possible without departing from the gist of the present invention.

[0048] In the above embodiment, an example has been described in which the capacitor conductor 17 does not overlap with the second conductor 10B of the inductor 10 when viewed from the second direction D2. However, the capacitor conductor 17 may overlap with the second conductor 10B of the inductor 10 when viewed from the second direction D2. In this configuration, the capacitance formed by the capacitor conductor 17 and the second conductor 10B can be increased.

[0049] In the above embodiment, the capacitor conductor 17 is disposed closer to the principal surface 2d than the end of the second conductor 10B of the inductor 10 on the principal surface 2d side. However, the capacitor conductor 17 may be disposed closer to the principal surface 2c than the end of the second conductor 10B of the inductor 10 on the principal surface 2d side. In other words, the position of the capacitor conductor 17 is not limited. It is sufficient that the capacitor conductor 17 and the second conductor 10B are in a positional relationship that allows magnetic field coupling.

[0050] In the electronic component 1 of the above embodiment, the resonator 9 may include other inductors and capacitor conductors. [Explanation of symbols]
