Title:
圧粉磁心及びその製造方法
Document Type and Number:
Japanese Patent JP7419127
Kind Code:
B2
Abstract:
To provide a powder magnetic core that has particularly high magnetic permeability and that can contribute to miniaturization of a magnetic component such as a reactor, and a method of manufacturing the same.MEANS FOR SOLVING THE PROBLEM: A powder magnetic core includes a pressurized powder body that is made from malleable powder and nanocrystal powder in which the ratio (L1/L2) between a major axis L1 and a minor axis L2 is in the range of 1.1-5.0. The ratio of powder, in which an orientation angle of the nanocrystal powder with respect to a direction perpendicular to a molding direction of the pressurized powder body is less than 45°, is in the range of 65-85%.SELECTED DRAWING: None
