  • Patent number: 11915851
    Abstract: An inductor includes an external terminal and an element body that includes a magnetic portion containing a magnetic powder and a coil embedded in the magnetic portion. The magnetic powder has a particle size D50 at 50% of the cumulative volume of 5 ?m or less, a D90/D10 of 19 or lower, and a Vickers hardness of 1000 (kgf/mm2) or lower, the D90/D10 being the ratio of particle size D90 at 90% of the cumulative volume to particle size D10 at 10% of the cumulative volume in the cumulative particle size distribution by volume. In the magnetic portion, the packing density of the magnetic powder by volume is 60% or higher.

  • Publication number: 20220310315
    Abstract: An inductor including a conductor having a plate thickness is embedded in a core containing magnetic powder. The core includes a mounting surface facing a mounting substrate side at the time of mounting, an upper surface facing the mounting surface, and a pair of end surfaces orthogonal to the mounting surface. The conductor includes a conductive wire extending inside the core over the pair of end surfaces, and a pair of electrode terminals. Each electrode terminal includes an electrode portion at respective end portions of the conductive wire and exposed to the mounting surface, and first and second bent portions having a first bend and second bend, respectively, which are each 2.0 times to 3.0 times the plate thickness. When one of the first and second bends is 2.0 times or more the plate thickness, the other is less than 3.0 times the plate thickness.

  • Patent number: 11424068
    Abstract: An inductor includes a main body having a bottom surface, a top surface positioned opposite to the bottom surface, four side surfaces connected to the bottom surface and the top surface, a metal body that includes a first metal portion buried in the main body and second metal portions extending outward from respective opposite longitudinal ends of the first metal portion. The second metal portions are exposed from respective opposite side surfaces of the main body. In the inductor, each second metal portion is formed into a tabular shape having a first surface with a plating layer and a second surface positioned opposite to the first surface. Each second metal portion is formed into an external terminal and includes a first bend and a second bend that are formed by bending the second metal portion.
