Magnetic Core for Frequency Air Conditioner Inductor

Magnetic Core for Frequency Air Conditioner Inductor

Sendust Core is made from 6%Al,9%Si and 85%Fe. It is mainly used to replace iron powder core as its core loss is 80% less than the powdered iron, so it can be applied with the frequency above 8kHz.
