Publication number: 20210327642Abstract: A winding body and method to avoid short-circuiting due to contact between conductors, and to suppress occurrence of structural defects such as cracks. A continuous thin band is folded at a folding site and wound helically. The folding site has a cutout portion, and folding at the folding site so that a conductor portion overlap another conductor portion causes the cutout portion to be formed into a recessed portion having a larger space than a gap between the conductor portions. A part of the conductor inside the folding site can be stowed in the recessed portion. The continuous thin band has a thickness desirably equal to or less than twice a skin depth with respect to a driving frequency of a coil component.Type: ApplicationFiled: April 19, 2021Publication date: October 21, 2021Applicant: Murata Manufacturing Co., Ltd.Inventors: Gota SHINOHARA, Kenichiro MAKI

Publication number: 20210108280Abstract: A metal strip contains a metal magnetic material as a main component, and is formed such that a surface roughness of one main surface is higher than a surface roughness of an other main surface. The other main surface is formed in a smooth surface having a high surface smoothness, and the one main surface is subjected to surface treatment such that a striped pattern composed of a recessed portion and a protruding portion is continuously formed. After a continuous strip is made by a single-roll liquid quenching method, the striped pattern is formed by subjecting one main surface of the continuous strip to surface treatment. A magnetic core is obtained by winding the metal strip in an annular shape, and a coil component, such as a common mode choke coil, is obtained by using the magnetic core. Thus, the metal strip has sufficient toughness and good mechanical strength.Type: ApplicationFiled: December 22, 2020Publication date: April 15, 2021Applicant: Murata Manufacturing Co., Ltd.Inventor: Gota SHINOHARA
