Title:
A powder magnetic core and a reactor
Document Type and Number:
Japanese Patent JP6243298
Kind Code:
B2
Abstract:
A soft magnetic member is formed such that, when a differential relative permeability in an applied magnetic field of 100 A/m is represented by a first differential relative permeability µ'L, and when a differential relative permeability in an applied magnetic field of 40 kA/m is represented by a second differential relative permeability µ'H, a ratio of the first differential relative permeability µ'L to the second differential relative permeability µ'H satisfies a relationship of µ'L/µ'H¤10, and a magnetic flux density in an applied magnetic field of 60 kA/m is 1.15 T or higher.
