Magnetic-plated Wire (magnetic wire) is a copper conductor covered with a thin layer of highly magnetic material, over which a polyurethane insulating film is enameled.

Magnetic-plated Wire(FPW)

Product Inquiry

When used for high-frequency coils, it reduces high-frequency losses by 10% compared to conventional polyurethane enameled copper wire. The reduction is due to the magnetic shielding, which lowers the proximity effect generally occurring in these types of coil, evenly distributes electric current in the conductor, and decreases the effective resistance of the conductor.
