  • Publication number: 20240055174
    Abstract: An inductor component includes a substantially rectangular parallelepiped device body including a first lateral surface and includes a coil conductor layer formed into a spiral wound more than one turn on a main surface parallel to the first lateral surface inside the device body. In the coil conductor layer, a wiring spacing between two wiring portions adjacent to each other (straight portions) in a first direction from an inner side portion to an outer side portion of the coil conductor layer differs from a wiring spacing of two wiring portions adjacent to each other (curved portions) in a second direction from the inner side portion to the outer side portion of the coil conductor layer, the second direction differing from the first direction.

  • Publication number: 20220238270
    Abstract: An inductor component comprising an element body; a coil disposed in the element body; and a first external electrode and a second external electrode disposed on the element body and electrically connected to the coil. The coil has a helical structure in which the coil is wound while proceeding along an axis such that the axis is parallel to a bottom surface of the element body and intersects with first and second side surfaces of the element body. The coil includes coil wirings laminated along the axis and wound along a plane, and a via wiring connecting the coil wirings. The first coil wiring is on a central side in the axial direction of the coil relative to the second coil wiring, and a first pad part of the first coil wiring is adjacent to a second wiring part of the second coil wiring in the axial direction.

  • Publication number: 20220115171
    Abstract: A high-frequency inductor component comprises an element body; a coil within the element body and having a helical structure in which the coil is wound along an axial direction; and first and second external electrodes on the element body and electrically connected to the coil. The element body includes first and second end surfaces that face each other and a bottom surface connected between these end surfaces. The first and second external electrodes are respectively formed from the first and second end surfaces to the bottom surface. The element body includes an insulating layer of a non-magnetic material, and internal and external magnetic members containing a magnetic material. The internal magnetic member lies where the coil is present in the axial direction, and the external magnetic member lies outside of the coil in the axial direction. The inductor component has an inductance value of 100 nH or less.
