  • Publication number: 20240266108
    Abstract: An electronic component includes an element body including a first principal surface and a second principal surface opposing each other, and first and second external electrodes disposed on the first principal surface and separated from each other. The element body includes a first region including the first principal surface and a second region located between the first region and the second principal surface. The first region includes a portion located between the first and second external electrodes. The portion included in the first region is in contact with the first and second external electrodes. When viewed in a direction in which the first principal surface and the second principal surface oppose each other, the portion included in the first region covers an end of each of the first and second external electrodes. The first region has hardness greater than that of the second region.

  • Publication number: 20240234014
    Abstract: A coil component includes an element body, a coil, a first terminal electrode, and a second terminal electrode. The coil has a coil axis extending in a direction in which a pair of side surfaces face each other. The first terminal electrode and the second terminal electrode have first electrode portions exposed on end surfaces and second electrode portions exposed on a main surface, respectively, and are not exposed on each of the pair of side surfaces. In a direction in which a pair of main surfaces face each other, a distance between each of ends of the first electrode portions on the main surface side and the main surface is larger than a distance between a top portion of the coil closest to the main surface and the main surface.

  • Publication number: 20230402216
    Abstract: A coil includes a plurality of coil conductors. The coil includes a plurality of connection portions each at which adjacent coil conductors of the plurality of coil conductors are electrically connected to each other and the adjacent coil conductors overlap each other. The plurality of connection portions include a first connection portion and a second connection portion that is farther from an electrode portion on a main surface than the first connection portion. A second area where the adjacent coil conductors overlap each other in the second connection portion is larger than a first area where the adjacent coil conductors overlap each other in the first connection portion.

  • Publication number: 20230326661
    Abstract: The mainline pattern and the pair of bypass patterns in the multilayer inductor can be regarded as three inductors connected in parallel in the element body. That is, in the multilayer inductor, paralleling of the inductance is realized in the element body by the mainline pattern and the pair of bypass patterns. Therefore, the inductance value of the multilayer inductor as a whole can be reduced.

  • Publication number: 20230317360
    Abstract: In the multilayer inductor, the extending direction of the connection portion is a direction along the turn portion when viewed from the extending direction of the coil axis. In this case, the change of the current route at the junction portion between the turn portion and the connection portion becomes gentle. Therefore, the signal loss at the junction portion is reduced, a high Q value can be achieved.
