Title:
MAGNETIC CORE
Document Type and Number:
WIPO Patent Application WO/1991/015020
Kind Code:
A1
Abstract:
A magnetic core obtained by winding a long sheet of thin alloy or by laminating short sheets thereof. The surface roughness of the thin alloy sheet or sheets is limited to lie within a predetermined range in order to improve the squareness ratio of the magnetic core. The magnetic core exhibits excellent squareness ratio characteristic and magnetic saturation characteristic in high-frequency regions.
