Publication number: 20220115171Abstract: 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.Type: ApplicationFiled: September 16, 2021Publication date: April 14, 2022Applicant: Murata Manufacturing Co., Ltd.Inventors: Tsuyoshi TAKAMATSU, Keiichi YOSHINAKA, Minoru MATSUNAGA
