  • Patent number: 9787276
    Abstract: An electronic component includes a device body and first through n-th LC parallel resonators connected in series with each other. The first through n-th LC parallel resonators respectively include first through n-th inductors and first through n-th capacitors. The first through n-th inductors are disposed in a first direction in the device body in this order. The first and n-th inductors are provided with a spiral shape or a helical shape such that they turn around respective winding axes extending along a second direction which is perpendicular or substantially perpendicular or substantially perpendicular or substantially perpendicular to the first direction. At least one of the second through (n?1)-th inductors is provided with a helical shape such that it turns around a winding axis extending along the first direction.
    Type: Grant

  • Patent number: 8754724
    Abstract: A multilayer electronic component and a multilayer electronic component manufacturing method are capable of easily controlling the degree of magnetic field coupling between inductors. Via-hole conductors are arranged so that they extend in a lamination direction in a laminate, and function as a first inductor. Via-hole conductors are arranged so that they extend in the lamination direction in the laminate, and function as a second inductor. A first capacitor and the first inductor define a first resonance circuit. A second capacitor and the second inductor define a second resonance circuit. The via-hole conductors are arranged in a first insulating layer so that they are spaced apart from each other by a first distance. The via-hole conductors are arranged in a second insulating layer so that they are spaced apart from each other by a second distance that is different from the first distance.
