Introduction
Filter Inductance Iron Core
Due to different appearance, amorphous core include plastic Fe-based amorphous core and epoxy Fe-based wound amorphous core; According to the size, this Fe-based magnetic core is divided into high saturation amorphous beads and filter inductance iron cores. It can used in iron-based amorphous filter inductor and spike suppressor.
COMPARE
