  • Patent number: 10476466
    Abstract: An electronic component includes a multilayer body constituted by insulator layers that are laminated in a laminating direction, a primary coil including one or more primary coil conductor layers, a secondary coil including one or more secondary coil conductor layers, and a tertiary coil including one or more tertiary coil conductor layers. The primary coil conductor layers, the secondary coil conductor layers, and the tertiary coil conductor layers are arrayed in the laminating direction. The primary coil, the secondary coil, and tertiary coil constitute a common mode filter, and intervals between two among the one or more primary coil conductor layers, the one or more secondary coil conductor layers, and the one or more tertiary coil conductor layers, every two of those being adjacent to each other in the laminating direction, are not even.

  • Patent number: 10181374
    Abstract: In an electronic component, a primary coil is electrically connected between a first outer electrode and a fourth outer electrode, a secondary coil is electrically connected between a second outer electrode and a fifth outer electrode, a tertiary coil is electrically connected between a third outer electrode and a sixth outer electrode, and a first inter-layer connection conductor, a second inter-layer connection conductor, and a third inter-layer connection conductor are electrically connected to the end portions at an inner side of a first coil conductor layer, a second coil conductor layer, and a third coil conductor layer, respectively. The first inter-layer connection conductor, the second inter-layer connection conductor, and the third inter-layer connection conductor are not positioned at one side of a second perpendicular direction, compared with a magnetic core, when viewed from a laminating direction.

  • Patent number: 10176918
    Abstract: An electronic component includes a first ceramic substrate having a first principal surface on the upper side and a second principal surface on the lower side, a multilayer body constituted by a plurality of insulator layers each made of a material containing resin and laminated on the first principal surface, a first coil disposed in and/or on the multilayer body, a first relay conductor connected to the first coil, and a first outer electrode disposed on the first ceramic substrate and electrically connected to the first relay conductor. The plurality of insulator layers include one or more first insulator layers in each of which a first corner has a shape cut away as a first cut-away portion, the first relay conductor is disposed in the first cut-away portion, and the plurality of insulator layers include a second insulator layer that is contacted with the first relay conductor from below.

  • Patent number: 10115519
    Abstract: An electronic component includes a primary coil including n primary coil conductor layers and a parallel primary coil conductor layer, and secondary and tertiary coils including respectively n secondary and tertiary coil conductor layers. Respective ones of the primary, secondary and tertiary coil conductor layers are arrayed alternately in this order from one side toward other side in laminating direction. The parallel primary coil conductor layer is electrically connected to a predetermined primary coil conductor layer, has the substantially same shape as the predetermined primary coil conductor layer in a plan view, and is disposed on the other side in the laminating direction relative to the tertiary coil conductor layer disposed at a farthest position on the other side in the laminating direction.
