Publication number: 20170316867Abstract: Provided is a coil component including a coil portion that has two ring-shaped planar coil portions individually including a coil-wound portion and an insulative resin layer which covers the periphery of the coil-wound portion within the same layer as the coil-wound portion, an insulative resin layer being interposed between the planar coil portions adjacent to each other in the stacking direction of the planar coil portions, and a pair of insulative resin layers being respectively positioned on one end side and the other end side of the two planar coil portions in the stacking direction; and a covering portion that covers the coil portion. In regard to the stacking direction, the thickness of the insulative resin layer is thinner than the thickness of each of the pair of insulative resin layers.Type: ApplicationFiled: April 24, 2017Publication date: November 2, 2017Applicant: TDK CORPORATIONInventors: Akifumi KAMIJIMA, Masamichi TANIGUCHI, Makoto ENDO, Tohru INOUE

Publication number: 20170162316Abstract: In a coil component, an inorganic layer which is provided on a lower surface side of a coil has a thermal conductivity higher than that of a resin layer with which an upper surface of the coil is covered and gaps between windings are filled. As a result, heat transfer from the inside of the coil to the outside is supplemented via the inorganic layer. That is, heat transfer of the coil via the inorganic layer is facilitated, and heat dissipation of the coil component improves.Type: ApplicationFiled: November 29, 2016Publication date: June 8, 2017Applicant: TDK CORPORATIONInventors: Makoto ENDO, Masamichi TANIGUCHI, Katsunori OSANAI

Publication number: 20160293334Abstract: A lower electrode (4) can have an uneven surface structure. An upper electrode (6) can also have the uneven surface structure. A projecting portion of the upper electrode (6) projecting to the lower electrode side is positioned in a gap between projecting portions of the lower electrode (4) and the lower electrode (4) includes Cu as a main component. Young's moduli of a substrate (1), a stress adjustment layer (2), and the lower electrode (4) have a specific relation. Also, corner portions of radii (R1) of curvature positioned inside a projecting portion (4b) have a specific relation.Type: ApplicationFiled: March 29, 2016Publication date: October 6, 2016Applicant: TDK CORPORATIONInventors: Shinji EHARA, Ikuhito ONODERA, Eiko WAKATA, Katsunori OSANAI, Masamichi TANIGUCHI
