Summary of the Invention

Problems to be Solved by the Invention

[0004] One aspect of this disclosure aims to provide an electronic component capable of suppressing a decrease in characteristics caused by magnetic flux leakage.

Means for Solving the Problems

[0005] (1) An electronic component relating to one aspect of the present disclosure comprises a body having a pair of main surfaces facing each other, and a first inductor and a second inductor disposed within the body, wherein the first inductor includes a first conductor and a second conductor extending in the opposing direction of the pair of main surfaces, a first connecting conductor positioned closer to one main surface and connecting the end of the first conductor on one main surface side to the end of the second conductor on one main surface side, and a second connecting conductor positioned closer to the other main surface and connecting the end of the first conductor on the other main surface side to the end of the second conductor on the other main surface side, wherein the second inductor comprises a third conductor and a fourth conductor extending in the opposing direction of the pair of main surfaces, and one main surface The second inductor is composed of a third connecting conductor positioned closer to the main surface and connecting one end of the third conductor on the main surface side with one end of the fourth conductor on the main surface side, and a fourth connecting conductor positioned closer to the other main surface and connecting the other end of the third conductor on the main surface side with the other end of the fourth conductor on the main surface side, the first connecting conductor and the third connecting conductor are positioned at the same position in the opposing direction, and the second inductor is composed of a plurality of third conductors and a plurality of fourth conductors and a plurality of third connecting conductors, and the first angle θ1 (θ1>0°) formed by two adjacent third connecting conductors when viewed from the opposing direction is greater than or equal to the second angle θ2 formed by the first connecting conductor and the third connecting conductor adjacent to the first connecting conductor.

[0006] In an electronic component relating to one aspect of this disclosure, the first angle θ1 (θ1>0°) formed by two adjacent third connecting conductors when viewed from opposite directions is greater than or equal to the second angle θ2 formed by the first connecting conductor and the adjacent third connecting conductor. This makes it possible to reduce the space (region) formed between the first inductor and the second inductor in the electronic component. Therefore, leakage of magnetic flux from the space between the first inductor and the second inductor can be suppressed in the electronic component. Consequently, the deterioration of characteristics caused by magnetic flux leakage can be suppressed in the electronic component.

[0007] (2) In the electronic component described in (1) above, when viewed from the opposite direction, the third connecting conductor adjacent to the first connecting conductor has a first portion extending in one direction and a second portion extending in another direction intersecting the first direction, and the first angle θ1 formed by two adjacent third connecting conductors may be greater than or equal to the second angle θ2 formed by the first connecting conductor and the first portion. In this configuration, the space (region) formed between the first connecting conductor of the first inductor and the first portion of the third inductor conductor of the second inductor can be reduced. Therefore, in the electronic component, leakage of magnetic flux from the space between the first inductor and the second inductor can be suppressed. Consequently, in the electronic component, a decrease in performance due to magnetic flux leakage can be suppressed.

[0008] (3) In the electronic component described in (2) above, the direction in which the first portion extends is along the direction in which the first connecting conductor extends, and the second portion may extend away from the first connecting conductor as it moves from one end connected to the first portion toward the other end of the second portion.

[0009] (4) In any one of the electronic components described in (1) to (3) above, at least a portion of the first connecting conductor of the first inductor and the third connecting conductor of the second inductor may overlap when viewed from the opposite direction. In this configuration, since a portion of the first connecting conductor and the third connecting conductor are arranged to overlap, the first inductor and the second inductor can be efficiently arranged within the limited space inside the component.

[0010] (5) In any one of the electronic components described in (1) to (4) above, the axial direction of the first inductor, which is composed of a first conductor, a second conductor, a first connecting conductor and a second connecting conductor, may intersect the axial direction of the second inductor, which is composed of a third conductor, a fourth conductor, a third connecting conductor and a fourth connecting conductor, when viewed from the opposite direction. In this configuration, coupling between the first inductor and the second inductor can be suppressed.

[0011] (6) In any one of the electronic components described in (1) to (5) above, the third connecting conductor adjacent to the first connecting conductor of the first inductor may be longer than the other third connecting conductors in the second inductor. In this way, the inductance of the second inductor can be adjusted by changing the length of each of the multiple third connecting conductors. [Effects of the Invention]

[0024] In this embodiment, "equivalent" means not only being equal, but also including slight differences or manufacturing tolerances within a predetermined range.

[0054] The first inductor conductor 13C extends along the first extending direction D11. The first extending direction D11 is in the same direction as the first direction D1. The first portion 13Ea of the third inductor conductor 13E extends along the second extending direction (one direction) D12. The second portion 13Eb of the third inductor conductor 13E extends along the third extending direction (other direction) D13. The first extending direction D11 and the second extending direction D12 intersect. The first extending direction D11 and the third extending direction D13 intersect. The second extending direction D12 and the third extending direction D13 intersect.

[0055] The first portion 13Ea of the third inductor conductor 13E was positioned at an angle to the first inductor conductor 13C. The distance K1 between one end of the first portion 13Ea of the third inductor conductor 13E (the end on the end face 2a side) and the first inductor conductor 13C was shorter than the distance K2 between the other end of the first portion 13Ea of the third inductor conductor 13E (the end on the end face 2b side) and the first inductor conductor 13C (K1 > K2). The first portion 13Ea of the third inductor conductor 13E was positioned so that it moved away from the first inductor conductor 13C from one end to the other.

[0056] The second portion 13Eb of the third inductor conductor 13E is positioned at an angle to the first inductor conductor 13C. The distance K2 between one end of the second portion 13Eb of the third inductor conductor 13E (the end on the end face 2a side) and the first inductor conductor 13C is longer than the distance K3 between the other end of the second portion 13Eb of the third inductor conductor 13E (the end on the end face 2b side) and the first inductor conductor 13C (K2 > K3). The second portion 13Eb of the third inductor conductor 13E is positioned so that it approaches the first inductor conductor 13C as it moves from one end to the other. The second portion 13Eb extends away from the first inductor conductor 14C of the inductor L5 as it moves from one end connected to the first portion 13Ea to the other end of the second portion 13Eb.

[0057] The third inductor conductor 13E of inductor L4 is positioned adjacent to the first inductor conductor 14C of inductor L5. Specifically, the first portion 13Ea of the third inductor conductor 13E and the first inductor conductor 14C are positioned adjacent to each other. The first inductor conductor 14C adjacent to the third inductor conductor 13E extends along the fourth extending direction D14. In this embodiment, the second extending direction D12 of the first portion 13Ea of the third inductor conductor 13E and the fourth extending direction D14 of the first inductor conductor 14C are in the same direction. That is, in this embodiment, the first portion 13Ea of the third inductor conductor 13E and the first inductor conductor 14C are substantially parallel. The length of the first portion 13Ea is equivalent to the length of the first inductor conductor 14C adjacent to the first portion 13Ea.

[0058] The first angle θ1 formed by the first inductor conductor 13C and the first portion 13Ea of the third inductor conductor 13E is greater than or equal to the second angle θ2 formed by the first portion 13Ea of the third inductor conductor 13E and the first inductor conductor 14C (θ1 ≥ θ2). In other words, the second angle θ2 formed by the first portion 13Ea of the third inductor conductor 13E and the first inductor conductor 14C is less than or equal to the first angle θ1 formed by the first inductor conductor 13C and the first portion 13Ea of the third inductor conductor 13E. The first angle θ1 is greater than 0° (θ1 > 0°). In this embodiment, the second angle θ2 is 0°. That is, in this embodiment, the first angle θ1 formed by the first inductor conductor 13C and the first portion 13Ea of the third inductor conductor 13E is greater than the second angle θ2 formed by the first portion 13Ea of the third inductor conductor 13E and the first inductor conductor 14C. The first angle θ1 formed by the first inductor conductor 13C and the first portion 13Ea of the third inductor conductor 13E is the angle formed by a virtual line along the extending direction of the first inductor conductor 13C and a virtual line along the extending direction of the first portion 13Ea. The second angle θ2 formed by the first portion 13Ea of the third inductor conductor 13E and the first inductor conductor 14C is the angle formed by a virtual line along the extending direction of the first portion 13Ea and a virtual line along the extending direction of the first inductor conductor 14C.

[0059] Viewed from the second direction D2, the space (region) S1 formed between the first inductor conductor 13C and the third inductor conductor 13E is larger than the space S2 formed between the first portion 13Ea of the third inductor conductor 13E and the first inductor conductor 14C.

[0060] Multiple first conductors 13A of inductor L4 are arranged in a line along the third direction D3 at regular intervals. Multiple second conductors 13B of inductor L4 are arranged in a line along the third direction D3 at regular intervals. The axial direction of inductor L4 is approximately along the third direction D3.

[0061] The plurality of first conductors 14A of the inductor L5 are arranged side by side along the third direction D3 at a constant interval K11. The plurality of second conductors 14B of the inductor L5 are arranged side by side at intervals in a direction intersecting the third direction D3. The intervals between the plurality of second conductors 14B are different. To distinguish the three second conductors 14B, they are denoted as the second conductor 14Ba, the second conductor 14Bb, and the second conductor 14Bc. In the present embodiment, the interval (distance) K12 between the second conductor 14Ba and the second conductor 14Bb is shorter than the interval K13 between the second conductor 14Bb and the second conductor 14Bc (K12 < K13). The interval K11 between the first conductors 14A may be equal to the interval K12 between the second conductor 14Ba and the second conductor 14Bb. The inductor L5 has a substantially W-shaped configuration when viewed from the second direction D2. The axial direction of the inductor L5 is different from the axial direction of the inductor L4.

[0062] FIG. 13 is a view showing the electronic component 1 shown in FIG. 2 from the main surface 2c side. As shown in FIG. 13, when viewed from the second direction D2, a part of the third inductor conductor 13E of the inductor L4 and a part of the second inductor conductor 14D of the inductor L5 overlap. That is, a part of the third inductor conductor 13E of the inductor L4 and a part of the second inductor conductor 14D of the inductor L5 are arranged to face each other in the second direction D2.

[0063] As described above, in the electronic component 1 according to the present embodiment, when viewed from the second direction D2, the first angle θ1 formed by the adjacent first inductor conductor 13C and the third inductor conductor 13E is not less than the second angle θ2 formed by the first portion 13Ea of the third inductor conductor 13E of the inductor L4 and the first inductor conductor 14C of the inductor L5 adjacent to the first portion 13Ea. Thereby, in the electronic component 1, the space (region) formed between the inductor L4 and the inductor L5 can be reduced. Therefore, in the electronic component 1, it is possible to suppress the leakage of magnetic flux from the space between the inductor L4 and the inductor L5. Accordingly, in the electronic component 1, it is possible to suppress the deterioration of characteristics due to the leakage of magnetic flux.

[0064] In the electronic component 1 according to this embodiment, when viewed from the second direction D2, a portion of the third inductor conductor 13E of inductor L4 and a portion of the second inductor conductor 14D of inductor L5 overlap. With this configuration, inductors L4 and L5 can be efficiently arranged within the limited space inside the base body 2.

[0065] In the electronic component 1 according to this embodiment, the third inductor conductor 13E of the inductor L4 has a first portion 13Ea and a second portion 13Eb. The first portion 13Ea is arranged adjacent to the first inductor conductor 14C of the inductor L5 and extends in the same direction as the first inductor conductor 14C. The second portion 13Eb extends in a direction intersecting the first portion 13Ea. The length of the third inductor conductor 13E is longer than the length of the first inductor conductor 13C. In this way, the inductance of the inductor L4 can be adjusted by changing the lengths of the first inductor conductor 13C and the third inductor conductor 13E.

[0066] In the electronic component 1 according to this embodiment, the axial direction of inductor L4 and the axial direction of inductor L5 are different (they intersect). As a result, the coupling between inductor L4 and inductor L5 can be suppressed in the electronic component 1.

[0067] While embodiments of the present invention have been described above, the present invention is not necessarily limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention.

[0068] In the above embodiment, an example was described in which the electronic component 1 includes inductors L1, L2, L3, L4, L5, L6, and L7. However, the electronic component 1 only needs to include at least inductors L4 and L5.

[0069] In the above embodiment, an example was described in which the inductor L4 comprises a first inductor conductor 13C, a second inductor conductor 13D, and a third inductor conductor 13E. However, the number of inductor conductors in inductor L4 is not limited. An example was described in which the inductor L5 comprises a first inductor conductor 14C and a second inductor conductor 14D. However, the number of inductor conductors in inductor L5 is not limited. [Explanation of symbols]
