[0039] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those of ordinary skill in the art without creative effort should fall into the scope of the present application.

[0040] The electronic component 1, such as a laminated chip inductor, generally comprises a component body 10, a first terminal electrode 11, a second terminal electrode 12 and a coil conductor 13, and the effective coil area enclosed by the coil conductor 13 will affect the inductance. In order to obtain higher inductance in the laminated chip inductor with limited layers, the area enclosed by the coil conductor 13 is generally increased. In the related art, as shown in Figure 1 The shape of the coil conductor 13 is generally rectangular, that is, the coil conductor 13 comprises an upper edge conductor 130, a first side edge conductor 131, a lower edge conductor 133 and a second side edge conductor 135 connected in sequence, however, when the area enclosed by the coil conductor 13 is increased, that is, the length of each conductor is increased, the distance between the coil conductor 13 and the terminal electrode is reduced, resulting in increased parasitic capacitance, and the total length of the coil conductor 13 is also increased, so that the total resistance of the coil conductor 13 is increased, resulting in increased heat loss of the coil conductor 13, thereby the quality factor of the laminated chip inductor cannot be effectively improved.

[0041] The technical solutions of the present application will be further described below with reference to the embodiments and the drawings.

[0042] Please refer to Figure 2In a first aspect, an electronic component 1 is provided. The electronic component 1 includes a component body 10, a first terminal electrode 11, a second terminal electrode 12, and a coil conductor 13. The first terminal electrode 11 is disposed on one side of the component body 10 in a first direction X. The second terminal electrode 12 is disposed on another side of the component body 10 in the first direction X. The coil conductor 13 is disposed on the component body 10 and is electrically connected to the first terminal electrode 11 and the second terminal electrode 12. The coil conductor 13 has an upper edge conductor 130, a first side edge conductor 131, a plurality of first inclined edge conductors 132, a lower edge conductor 133, a plurality of second inclined edge conductors 134, and a second side edge conductor 135. The upper edge conductor 130 and the lower edge conductor 133 extend along the first direction X. The first side edge conductor 131 and the second side edge conductor 135 extend along a second direction Y. The first inclined edge conductors 132 are disposed corresponding to the first terminal electrode 11. The first inclined edge conductors 132 are disposed obliquely relative to the first side edge conductor 131 and the lower edge conductor 133, and an included angle is formed between two adjacent first inclined edge conductors 132. The second inclined edge conductors 134 are disposed corresponding to the second terminal electrode 12. The second inclined edge conductors 134 are disposed obliquely relative to the second side edge conductor 135 and the lower edge conductor 133, and an included angle is formed between two adjacent second inclined edge conductors 134. The first direction X is perpendicular to the second direction Y.

[0043] In the electronic component 1 provided in the first aspect, the component body 10 is used to carry the first terminal electrode 11, the second terminal electrode 12, and the coil conductor 13. The first terminal electrode 11 and the second terminal electrode 12 are used to realize physical conduction with the outside. The coil conductor 13 is used to enclose an inductance region. Since the circumference of a circle is the shortest under the same area, by setting the part of the coil conductor 13 corresponding to the first terminal electrode 11 as a plurality of first inclined edge conductors 132 and setting the part of the coil conductor 13 corresponding to the second terminal electrode 12 as a plurality of second inclined edge conductors 134, the more the number of the first inclined edge conductors 132 and the second inclined edge conductors, the closer the shape enclosed by the plurality of first inclined edge conductors 132 and the plurality of second inclined edge conductors 134 to a circle. In the case of keeping the area of the inductance region enclosed by the coil conductor 13 unchanged or as much as possible, that is, in the case of keeping the inductance of the coil conductor 13 unchanged, compared with the rectangular coil conductor in the related art and compared with the case where the number of the first inclined edge conductors 132 and the second inclined edge conductors is one, the total length of the coil conductor 13 can be reduced, so that the total resistance of the coil conductor 13 can be reduced, and thus the quality factor of the electronic component 1 can be improved. At the same time, compared with the rectangular coil conductor in the related art, the distance between the plurality of first inclined edge conductors 132 and the first terminal electrode 11 is farther, and the distance between the plurality of second inclined edge conductors 134 and the second terminal electrode 12 is farther, so that the parasitic capacitance generated by the electronic component 1 can be reduced, and thus the self-resonant frequency of the electronic component 1 can be improved.

[0044] Please refer toFigure 3 With Figure 4 In the present application, the component body 10 includes a plurality of insulating layers 100, the plurality of insulating layers 100 are stacked along a thickness direction Z of the electronic component 1, the thickness direction Z is perpendicular to the first direction X and the second direction Y, the coil conductor 13 includes a plurality of electrode layers 13a and a plurality of conductive portions 13b, each electrode layer 13a is disposed between two insulating layers 100, the conductive portion 13b penetrates the insulating layers 100 along the thickness direction Z and communicates with the electrode layers 13a on two opposite sides of the thickness direction Z, among the plurality of electrode layers 13a, one of the two electrode layers 13a on the two opposite sides of the thickness direction Z is electrically connected to the first terminal electrode 11, and the other is electrically connected to the second terminal electrode 12.

[0045] In the present embodiment, since the electrode layer 13a will not be a closed figure (otherwise the electrode layer 13a will be short-circuited), the coil conductor 13 has an upper edge conductor 130, a first side edge conductor 131, a plurality of first oblique edge conductors 132, a lower edge conductor 133, a plurality of second oblique edge conductors 134 and a second side edge conductor 135, that is, the projection of all the electrode layers 13a on the insulating layer 100 along the thickness direction Z will form the upper edge conductor 130, the first side edge conductor 131, the plurality of first oblique edge conductors 132, the lower edge conductor 133, the plurality of second oblique edge conductors 134 and the second side edge conductor 135 as shown in Figure 2

[0046] In the present application, the "upper" of the upper edge conductor 130 and the "lower" of the lower edge conductor 133 represent the upper and lower of the paper surface direction in Figure 2 Figure 2 ​​The first direction X is a direction pointing to the left-right direction. The above directions are examples for facilitating understanding of the shape of the coil conductor 13, and do not represent the actual directions of the electronic component 1 in actual application.

[0047] Optionally, the number of the first bevel conductors 132 can be two, three, four, or five, and the number of the second bevel conductors 134 can be two, three, four, or five, which can be selected according to actual conditions, and is not specifically limited in the embodiment.

[0048] In some embodiments, the number of the first bevel conductors 132 is two (as shown in FIG. 2A) or three (as shown in FIG. 2B), and the number of the second bevel conductors 134 is two (as shown in FIG. 2A) or three (as shown in FIG. 2B). Figure 2 Figure 5 Figure 2 Figure 5

[0049] By setting the number of the first bevel conductors 132 and the number of the second bevel conductors 134 to two or three, the shape enclosed by the plurality of first bevel conductors 132 and the plurality of second bevel conductors 134 is relatively close to a circle, which can better reduce the total resistance of the coil conductor 13, and the distance between the plurality of first bevel conductors 132 and the first terminal electrode 11 is relatively far, and the distance between the plurality of second bevel conductors 134 and the second terminal electrode 12 is also relatively far, which can balance the consideration of the quality factor and the self-resonant frequency of the electronic component 1, and can improve the quality factor and the self-resonant frequency of the electronic component 1.

[0050] Referring to FIG. 2A and FIG. 2B, in some embodiments, the included angle between two adjacent first bevel conductors 132 is a1, and the included angle a1 satisfies: 90°<a1<180°, and / or the included angle between two adjacent second bevel conductors 134 is a2, and the included angle a2 satisfies: 90°<a2<180. Figure 2

[0051] In an example, the included angle between two adjacent first bevel conductors 132 is a1, and the included angle a1 satisfies: 90°<a1<180°. The included angle between the first bevel conductors 132 is an obtuse angle, and is an angle protruding towards the first terminal electrode 11. Compared with the case where the included angle between the first bevel conductors 132 is an acute angle, the distance between the first bevel conductors 132 and the first terminal electrode 11 is relatively far, and at the same time, the area of the inductance region enclosed by the coil conductor 13 is relatively large, so that the quality factor and the self-resonant frequency of the electronic component 1 can be improved.

[0052] Exemplarily, the included angle a1 can be 100°, 110°, 120°, 130°, 140°, 150°, 160°, or 170°. ​​​​​

[0053] In another example, the angle between the two adjacent second bevel conductors 134 is a2, and the angle a2 satisfies: 90° < a2 < 180°. In this way, the angle between the two adjacent second bevel conductors 134 is an obtuse angle, and is an angle protruding towards the second terminal electrode 12. Compared with the case where the angle between the two adjacent second bevel conductors 134 is an acute angle, the distance between the second bevel conductors 134 and the second terminal electrode 12 is relatively far, and at the same time, the area of the inductance region enclosed by the coil conductor 13 is relatively large, so that the quality factor and the self-resonant frequency of the electronic component 1 can be improved.

[0054] For example, the angle a2 can be 100°, 110°, 120°, 130°, 140°, 150°, 160° or 170°.

[0055] In another example, the angle between the two adjacent first bevel conductors 132 is a1, and the angle a1 satisfies: 90° < a1 < 180°, and the angle between the two adjacent second bevel conductors 134 is a2, and the angle a2 satisfies: 90° < a2 < 180°.

[0056] In this way, the angle between the two adjacent first bevel conductors 132 is an obtuse angle, and is an angle protruding towards the first terminal electrode 11, and at the same time, the angle between the two adjacent second bevel conductors 134 is an obtuse angle, and is an angle protruding towards the second terminal electrode 12, so that the quality factor and the self-resonant frequency of the electronic component 1 can be better improved.

[0057] For example, the angle a1 can be 100°, 110°, 120°, 130°, 140°, 150°, 160° or 170°. Figure 6 In other embodiments, the angle between the two adjacent first bevel conductors 132 is a1, and the angle a1 satisfies: a1 > 180°, and / or, the angle between the two adjacent second bevel conductors 134 is a2, and the angle a2 satisfies: a2 > 180°. That is, the angle between the two adjacent first bevel conductors 132 is an angle concave towards the first terminal electrode 11, and the angle between the two adjacent second bevel conductors 134 is an angle concave towards the second terminal electrode 12. In this way, the first bevel conductors 132 are away from the first terminal electrode 11, and the second bevel conductors 134 are away from the second terminal electrode 12, so that the parasitic capacitance generated by the electronic component 1 is greatly reduced, and the self-resonant frequency of the electronic component 1 is improved.

[0058] In some embodiments, when the number of the first bevel conductors 132 is two or three, the angle a1 satisfies: 120° ≤ a1, and / or, a1 ≤ 150°.

[0059] In one example, the included angle a1 satisfies: 120°≤a1. In this way, the angle a1 can be made larger, so that the first hypotenuse conductor 132 has a larger distance from the first terminal electrode 11, which can better reduce the parasitic capacitance generated by the electronic component 1, thereby better improving the self-resonant frequency of the electronic component 1.

[0060] In another example, the included angle a1 satisfies: a1≤150°. In this way, the angle a1 can be made not too large, so that the coil conductor 13 can enclose a larger area of the inductance region.

[0061] In another example, the included angle a1 satisfies: 120°≤a1≤150°. For example, the included angle a1 can be 120°, 130°, 140°, or 150°.

[0062] In this way, on the one hand, the angle a1 can be made larger, so that the first hypotenuse conductor 132 has a larger distance from the first terminal electrode 11, which can better reduce the parasitic capacitance generated by the electronic component 1, thereby better improving the self-resonant frequency of the electronic component 1, and on the other hand, the angle a1 can be made not too large, so that the coil conductor 13 can enclose a larger area of the inductance region. In addition, when the number of first hypotenuse conductors 132 is two or three, the shape formed by the plurality of first hypotenuse conductors 132 can be closer to 1 / 4 of a circle, which can better reduce the total length of the coil conductor 13, thereby better reducing the total resistance of the coil conductor 13, and further better improving the quality factor of the electronic component 1.

[0063] In some embodiments, when the number of second hypotenuse conductors 134 is two or three, the included angle a2 satisfies: 120°≤a2, and / or, a2≤150°.

[0064] In one example, the included angle a2 satisfies: 120°≤a2. In this way, the angle a2 can be made larger, so that the second hypotenuse conductor 134 has a larger distance from the second terminal electrode 12, which can better reduce the parasitic capacitance generated by the electronic component 1, thereby better improving the self-resonant frequency of the electronic component 1.

[0065] In another example, the included angle a2 satisfies: a2≤150°. In this way, the angle a2 can be made not too large, so that the coil conductor 13 can enclose a larger area of the inductance region.

[0066] In another example, the included angle a2 satisfies: 120°≤a2≤150°. For example, the included angle a2 can be 120°, 130°, 140°, or 150°.

[0067] In this way, on the one hand, the angle a2 can be made larger, so that the second bevel conductor 134 has a larger distance from the second terminal electrode 12, and the parasitic capacitance generated by the electronic component 1 can be reduced better, so as to better improve the self-resonant frequency of the electronic component 1, and on the other hand, the angle a2 can be made not too large, so that the coil conductor 13 can enclose a larger area of inductance region. In addition, when the number of second bevel conductors 134 is two or three, the shape formed by the plurality of second bevel conductors 134 can be closer to 1 / 4 circle, and the total length of the coil conductor 13 can be reduced better, so as to better reduce the total resistance of the coil conductor 13, and further better improve the quality factor of the electronic component 1.

[0068] In some embodiments, the first terminal electrode 11 includes a first portion 110 and a second portion 111 connected to each other, the first portion 110 is arranged to extend along the first direction X, and the second portion 111 is arranged to extend along the second direction Y; and the second terminal electrode 12 includes a third portion 120 and a fourth portion 121 connected to each other, the third portion 120 is arranged to extend along the first direction X, and the fourth portion 121 is arranged to extend along the second direction Y. In this way, the first terminal electrode 11 and the second terminal electrode 12 are L-shaped, and the first terminal electrode 11 and the second terminal electrode 12 can be facilitated to realize physical conduction with the outside.

[0069] In some embodiments, in the first direction X, the lower edge conductor 133 is located between the first portion 110 and the third portion 120, and / or in the second direction Y, the first side edge conductor 131 is located above the second portion 111, and the second side edge conductor 135 is located above the fourth portion 121.

[0070] In an example, in the first direction X, the lower edge conductor 133 is located between the first portion 110 and the third portion 120. That is, in the first direction X, the length d1 of the lower edge conductor 133 is less than the distance d2 between the first portion 110 and the third portion 120.

[0071] In this way, the distance between the first bevel conductor 132 connected to the lower edge conductor 133 and the first portion 110 of the first terminal electrode 11 can be increased, and the distance between the second bevel conductor 134 connected to the lower edge conductor 133 and the third portion 120 of the second terminal electrode 12 in the first direction X can be increased, and the parasitic capacitance generated by the electronic component 1 can be reduced.

[0072] In another example, in the second direction Y, the first side edge conductor 131 is located above the second portion 111, and the second side edge conductor 135 is located above the fourth portion 121. That is, in the second direction Y, the connection between the first side edge conductor 131 and the first oblique edge conductor 132 is located above the second portion 111, and the connection between the second side edge conductor 135 and the second oblique edge conductor 134 is located above the fourth portion 121.

[0073] In this way, the distance between the first oblique edge conductor 132 connected to the first side edge conductor 131 and the second portion 111 of the first terminal electrode 11 in the second direction Y can be increased, and the distance between the second oblique edge conductor 134 connected to the second side edge conductor 135 and the fourth portion 121 of the second terminal electrode 12 can be increased, thereby reducing the parasitic capacitance generated by the electronic component 1.

[0074] In another example, in the first direction X, the lower edge conductor 133 is located between the first portion 110 and the third portion 120, and in the second direction Y, the first side edge conductor 131 is located above the second portion 111, and the second side edge conductor 135 is located above the fourth portion 121.
