Title:
INDUCTANCE COMPONENT, MAGNETIC-BIAS-APPLYING MEMBER, AND METHOD FOR MANUFACTURING MAGNETIC-BIAS-APPLYING MEMBER
Document Type and Number:
WIPO Patent Application WO/2014/092169
Kind Code:
A1
Abstract:
An inductance component (1) provided with the following: a magnetic core (10) that comprises a main magnetic-core body (12), said main magnetic-core body (12) having a magnetic-saturation-preventing air gap (16) in at least one place along the magnetic path thereof, and a magnetic-bias-applying member (14) that comprises a different material from the main magnetic-core body (12) and is positioned inside the aforementioned air gap (16); and a lead wire (20) attached to the magnetic core (10). This inductance component (1) is characterized in that the magnetic-bias-applying member (14) is formed by shaping a composite magnetic material into a slab, said composite magnetic material containing a powdered hard magnetic material for applying a magnetic bias, a powdered soft magnetic material for improving relative permeability, and a binder for binding said materials together. This magnetic device has good DC superimposition characteristics and low magnetic-property variability.
