Summary of the Invention

Problems to be Solved by the Invention

[0004] In an electronic component, in order to reduce the influence of an external electromagnetic field or the like on the characteristics of the electronic component, a shield (shield layer) is provided on the outer surface of the element body. The shield is electrically connected to a ground terminal connected to the ground. In electronic components, strengthening of the ground of the shield is required.

[0005] One aspect of this disclosure aims to provide an electronic component capable of strengthening the ground of the shield.

Means for Solving the Problems

[0006] (1) An electronic component relating to one aspect of the present disclosure comprises a body having a mounting surface and a main surface facing each other, and four sides connecting a pair of main surfaces; a shield covering the four sides of the body; a ground terminal disposed on the mounting surface and connected to ground; an inductor conductor and a capacitor conductor disposed within the body; a first connecting conductor electrically connecting a shield disposed on one of the four sides and a shield disposed on another side different from the one side; and a second connecting conductor electrically connecting the first connecting conductor and the ground terminal.

[0007] An electronic component relating to one aspect of this disclosure includes a first connecting conductor that electrically connects a shield located on one of the four sides with a shield located on a different side. The first connecting conductor is electrically connected to a ground terminal by a second connecting conductor. In this way, in the electronic component, the shield located on the side is electrically connected by the first connecting conductor, and the first connecting conductor constitutes an electrical path between the ground terminal and the shield. This allows the electronic component to strengthen the ground of the shield.

[0008] (2) In the electronic component described in (1) above, one side and the other side are arranged opposite each other, and the first connecting conductor may electrically connect the shields located on the pair of sides that are arranged opposite each other. In this configuration, the first connecting conductor electrically connects the shields located on the pair of sides that are separated (not adjacent) to each other. As a result, in the electronic component, the shields located on each of the pair of sides are directly electrically connected by the first connecting conductor. Therefore, the ground of the shields can be strengthened in the electronic component.

[0009] (3) In the electronic component described in (1) or (2) above, the first connecting conductor may electrically connect to each of the shields located on at least three of the four sides. This configuration further enhances the grounding.

[0010] (4) Any one of the electronic components described in (1) to (3) above may have a portion in which the capacitor conductor and the first connecting conductor overlap when viewed from the direction opposite to the mounting surface and the main surface. In this configuration, the capacitance of the capacitor, which includes the capacitor conductor, can be adjusted.

[0011] (5) In any one of the electronic components described in (1) to (4) above, the first connecting conductor is positioned between the inductor conductor and the capacitor conductor in the direction opposite to the mounting surface and the main surface, and the distance between the inductor conductor and the first connecting conductor in the opposite direction may be longer than the distance between the capacitor conductor and the first connecting conductor in the opposite direction. In this configuration, the capacitance of the capacitor, which includes the capacitor conductor, can be adjusted. In addition, since a distance is ensured between the inductor conductor and the first connecting conductor, electrical interference between the inductor conductor and the first connecting conductor can be suppressed.

[0012] (6) In any one of the electronic components described in (1) to (4) above, the first connecting conductor may be positioned between the main surface and the inductor conductor in the direction opposite to the mounting surface and the main surface. This configuration can suppress electrical interference between the first connecting conductor and the other conductors.

[0013] (7) In any one of the electronic components described in (1) to (6) above, a plurality of inductor conductors may be provided, and the first connecting conductor may have a first part that electrically connects a shield located on one side with a shield located on the other side and is electrically connected to one inductor conductor, a second part that electrically connects a shield located on one side with a shield located on the other side and is electrically connected to another inductor conductor, and a third part that electrically connects the first part and the second part. In this configuration, in a configuration in which a plurality of resonators comprising inductors are provided, the ground of the shield can be strengthened.

[0014] (8)In any one of the electronic components (1) to (7) above, a plurality of first connection conductors may be arranged. With this configuration, the ground of the shield can be strengthened.

In other words, the distance K2 between the shielding conductor 19 and the capacitor conductor 24 is shorter than the distance K1 between the shielding conductor 19 and the inductor conductor 17.

[0050] Figure 9 is an equivalent circuit diagram of the electronic component 1 shown in Figure 1. As shown in Figure 1, the electronic component 1 includes an input port P1, an output port P2, a ground Gnd, inductors L1, L2, L3, L4, capacitors C1, C2, C3, C4, C5, C6, C7, and C8.

[0056] As described above, the electronic component 1 according to this embodiment includes a shield connecting conductor 19 that electrically connects the shield E located on the side surface 2e to the shield E located on the side surface 2f. The shield connecting conductor 19 is electrically connected to the second terminal electrode 4, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 via a ground conductor 55 by connecting conductors 20, 21, 22, 23, 25, 26, 27, 28, 33, 34, 35, 36, 39, 40, 43, 44, 51, 52, 53, and 54. Thus, in electronic component 1, the shield E located on sides 2e and 2f is electrically connected by the shield connecting conductor 19, and the shield connecting conductor 19 forms an electrical path between the second terminal electrode 4, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 (ground terminal) and the shield E. As a result, the ground of the shield E can be strengthened in electronic component 1. Consequently, the influence of external electromagnetic fields on electronic component 1 can be reduced.

[0057] Figure 10 shows the relationship between frequency and attenuation. In Figure 10, the horizontal axis represents the frequency band [MHz] and the vertical axis represents the attenuation [dB]. In Figure 10, the results for electronic component 1 are shown by the solid line G1, and the results for the comparative electronic component without the shield connecting conductor 19 are shown by the dashed line G2. As shown in Figure 10, in electronic component 1, the attenuation in the high frequency band (area enclosed by the dashed line) is improved compared to the comparative electronic component by strengthening the ground of shield E. Also, in electronic component 1, the attenuation due to magnetic coupling relaxation (area enclosed by the dashed line) is improved compared to the comparative electronic component by strengthening the ground of shield E.

[0058] In the electronic component 1 according to this embodiment, the shield connecting conductor 19 electrically connects the shields E located on opposite sides 2e and 2f. Thus, in the electronic component 1, the shield connecting conductor 19 electrically connects the shields E located on sides 2e and 2f that are far apart (not adjacent). As a result, in the electronic component 1, the shields E located on sides 2e and 2f are directly electrically connected by the shield connecting conductor 19. Therefore, the ground connection of the shields E can be strengthened in the electronic component 1.

[0059] In the electronic component 1 according to this embodiment, the shield connecting conductor 19 has a first portion 19A, a second portion 19B, and a third portion 19C. The first portion 19A and the second portion 19B each electrically connect the shield E located on side surface 2e and the shield E located on side surface 2f. The third portion 19C connects the first portion 19A and the second portion 19B. In this configuration, the first portion 19A and the second portion 19B constitute an electrical path between the second terminal electrode 4, the fourth terminal electrode 6, the fifth terminal electrode 7, and the sixth terminal electrode 8 and the shield E. Therefore, the electronic component 1 can further enhance the grounding.

[0060] In the electronic component 1 according to this embodiment, the capacitor conductor 24 overlaps when viewed from the second direction D2. That is, in the electronic component 1, the shield connection conductor 19 and the capacitor conductor 24 have an overlapping portion when viewed from the second direction D2. In this configuration, the capacitance of the capacitor, which includes the capacitor conductor 24, can be adjusted.

[0061] In the electronic component 1 according to this embodiment, the shielding conductor 19 is positioned between the inductor conductors 17 and 18 and the capacitor conductor 24. The distance K1 between the shielding conductor 19 and the inductor conductor 17 is longer than the distance K2 between the shielding conductor 19 and the capacitor conductor 24 (K1 > K2). In other words, the distance K2 between the shielding conductor 19 and the capacitor conductor 24 is shorter than the distance K1 between the shielding conductor 19 and the inductor conductor 17. In this configuration, the capacitance of the capacitor, which includes the capacitor conductor 24, can be adjusted. Furthermore, since a distance is ensured between the inductor conductors 17 and 18 and the shielding conductor 19, electrical interference between the inductor conductors 17 and 18 and the shielding conductor 19 can be suppressed.

The shielding conductor 84 is exposed on each of the end faces 2a, 2b, side surfaces 2e and 2f and is connected to the shield E.
