CO-BASED AMORPHOUS CORE

The Cobalt-based amorphous soft magnetic material with almost zero magnetostriction,

high permeability and low core loss, is suitable for such applications as magnetic snubber cores to suppress surge current and magnetic shielding sheet.

We are able to manufacture Co-based amorphous cores in various shapes, including Toroidal core, rectangular core, cut core and customized design cores.

APPLICATIONS

Magnetic amplifier, peak suppressor
Anti-DC meter / Watt-hour meter / Automotive parts
High frequency Switch Mode Power Supplies
Magnetic shield / Sensor / Frequency converter

Common mode choke, differential mode choke
