Patent number: 11854732Abstract: Disclosed herein is an apparatus that includes a substrate having first and second surfaces opposite to each other, a first coil pattern formed on the first surface of the substrate, and a second coil pattern formed on the second surface of the substrate. The first coil pattern includes first and second lines, and the second coil pattern includes third and fourth lines. The first line is greater in a number of turn than the second line, and the third line is greater in a number of turn than the fourth line. The first line is connected to the fourth line, and the third line is connected to the second line.Type: GrantFiled: October 30, 2019Date of Patent: December 26, 2023Assignee: TDK CorporationInventors: Junpei Hayama, Noritaka Chiyo, Shigeru Kaneko, Tomohiro Moriki, Takahiro Ohishi, Toshio Tomonari

Patent number: 11804654Abstract: Disclosed herein is a coil component that includes a substrate, a coil pattern formed on one surface of the substrate, and a magnetic layer comprising a composite material obtained by dispersing magnetic particles in resin and formed on the one surface of the substrate so as to cover the coil pattern. The coil pattern has a flat shape in which a thickness thereof is smaller than a radial width. Each of the magnetic particles has a flat shape in which a thickness thereof in a direction perpendicular to the one surface of the substrate is smaller than a diameter in a direction parallel to the one surface of the substrate. Some of the magnetic particles exist within a height range of the coil pattern with respect to the one surface of the substrate.Type: GrantFiled: August 16, 2021Date of Patent: October 31, 2023Assignee: TDK CORPORATIONInventors: Masaki Matsushima, Makoto Orikasa, Ryota Uchiyama, Junpei Hayama
