摘要： A wire-wound inductor component includes a core having a columnar shaft portion, first and second support portions provided on first and second end portions of the shaft portion, first and second terminal electrodes provided on the respective support portions, a wire wound around the shaft portion, and a cover member covering an upper surface of the shaft portion. In a height direction of the core, a distance between an upper surface and a top surface of the support portions is a top surface step, and a distance between a lower surface of the shaft portion and a bottom surface of the support portions is a bottom surface step. The top surface step is smaller than the bottom surface step and larger than a wire diameter, and a distance between the upper surface and an uppermost surface of the wire is larger than half of the top surface step.

摘要： An inductor component that includes a core that includes a substantially column-shaped shaft part and a pair of support parts at both ends of the shaft part; terminal electrodes that are respectively provided on the pair of support parts; and a wire that is wound around the shaft part and has end portions that are respectively connected to the terminal electrodes on the pair of support parts. The inductor component exhibits an impedance value of 2100Ω or higher for an input signal having a frequency of 500 MHz.

摘要： An insulating layer, which is composed of a material having a higher insulating property than a core, partially covers a surface of the core. A plating layer, which functions as an electrode, is stacked on a surface of the insulating layer. The surface area of the insulating layer is larger than the surface area of the plating layer and the plating layer is stacked inside a region covered by the insulating layer.

摘要： The wire wound inductor component includes a core including a columnar shaft portion extending in a first direction and first and second support portions at both end portions of the shaft portion, first and second terminal electrodes provided respectively on the first and second support portions, and a wire wound around the shaft portion. A distance between an upper surface of the shaft portion and a top surface of the first and second support portions in a second direction orthogonal to the first direction is defined as a top surface step, and a distance between a lower surface of the shaft portion and a bottom surface of the first and second support portions in the second direction is defined as a bottom surface step. The top and bottom surface steps are identical with each other, and the top and bottom surface steps are less than or equal to 50 μm.
