Title:

MAGNETIC CORE AND APPLIED PRODUCT MAKING USE OF THE SAME

Document Type and Number:

WIPO Patent Application WO/2006/104148

Kind Code:

A1

Abstract:

A magnetic core making use of an Fe-based amorphous alloy ribbon that simultaneously attains miniaturization and noise reduction through realization of high B_S; and an applied product making use of the same. There is provided a magnetic core making use of an Fe-based amorphous alloy ribbon, wherein the saturated magnetic flux density (B_S) of the Fe-based amorphous alloy ribbon is ≥ 1.60 T and wherein the ratio between magnetic flux density at a core external magnetic field of 80 A/m (B₈₀) and B_S of the Fe-based amorphous alloy ribbon, B₈₀/B_S, is ≥ 0.90.
