  • Publication number: 20220059280
    Abstract: Disclosed herein is a coil component that is surface-mountable on a substrate. The coil component includes a magnetic core, a wire wound around the magnetic core such that the coil axis direction is substantially parallel to the substrate, a terminal electrode connected to an end of the wire, and a low permeability part provided between the magnetic core and the terminal electrode. The low permeability part has a permeability lower than that of the magnetic core.

  • Publication number: 20210280359
    Abstract: Disclosed herein is a coil component that includes a winding core part and a wire wound around the winding core part. The winding core part includes a first winding area positioned on a first flange part side, a second winding area positioned on a second flange part side, and a third winding area positioned between the first and second winding areas. The wire includes a first section wound in a plurality of turns around the first winding area, a second section wound in a plurality of turns around the second winding area, and a third section wound in less than one turn around the third winding area. A shift amount of a winding position of the wire in an axial direction per turn is larger in the third section than in each of the first and second sections.

  • Publication number: 20200243257
    Abstract: Disclosed herein is a coil component that includes a winding core part and a wire wound around the winding core part. An i-th turn (i is an integer equal to or larger than 1) to a j-th turn (j is an integer equal to or larger than (i+2)) of the wire are wound in this order around the winding core part in an aligned state. A (j-th+1) turn of the wire is wound around a valley line formed by the i-th turn and a (i-th+1) turn. A (j-th+2) turn of the wire is wound adjacent to the j-th turn around the winding core part.
