  • Publication number: 20190260343
    Abstract: An LC filter includes first and second LC resonators including first and second inductors, respectively. In plan view from a winding axis direction of the first inductor, an air-core portion of the first inductor does not coincide with an air-core portion of the second inductor. The LC filter includes a bypass conductor that connects an intermediate portion of the first inductor between one end and another end of the first inductor and an intermediate portion of the second inductor between one end and another end of the second inductor.

  • Patent number: 10389329
    Abstract: A multilayer electronic component includes a multilayer body including insulator layers that are stacked, linear conductor traces each provided between adjacent ones of the insulator layers, and via conductors. A helical or substantially helical inductor is provided in the multilayer body. When viewed in the stacking direction of the multilayer body, all of the linear conductor traces, except a portion of one linear conductor trace, are superimposed within an annular or substantially annular linear conductor trace region. The portion of the one linear conductor trace is displaced inwardly from the annular or substantially annular linear conductor trace region.

  • Patent number: 9998086
    Abstract: An LC parallel resonator includes a plurality of dielectric layers stacked on top of one another, a capacitor electrode, and an inductor electrode. The inductor electrode defines a loop including a connection point, as a start point, connected to the capacitor electrode. The inductor electrode includes a first line electrode, first via electrodes, and second via electrodes. The first line electrode extends in a direction perpendicular or substantially perpendicular to a stacking direction of the dielectric layers. The first via electrodes arranged in parallel or substantially in parallel with one another extend in the stacking direction of the dielectric layers, and connect the capacitor electrode to the first line electrode. The second via electrodes arranged in parallel or substantially in parallel with one another extend in the stacking direction of the dielectric layers and are connected to the first line electrode.

  • Patent number: 9349524
    Abstract: A wire-wound electronic component includes a core having a winding base extending in an axial direction, a flange provided at an end of the winding base in the axial direction, and a wire wound around the winding base. An external electrode is provided on a plurality of side surfaces of the flange and is connected to an end of the wire, where the side surfaces are orthogonal to the axial direction. A connecting surface on which the end of the wire contacts with the external electrode is one of the side surfaces that is different from one of the side surfaces that functions as a mounting surface, and the external electrode extends from the mounting surface to the end of the wire in such a manner to turn in a direction same as a winding direction of the wire.
