Iron-based amorphous toroidal core from BIDRAGON

Introduction

Co-Based Amorphous Core

Due to different appearance, amorphous core include plastic Co-based amorphous core and epoxy Co-based amorphous toroidal 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. Bidragon Group have angaged in supplying amorphous & nano ribbon and core for many years, and our amorphous & nano core has passed the ISO 9001 certificate, at the same time, our producs has got CE certificate. Until now, our amorphous core and nano core has exported to many countries, including India, Korea, Russia, France, America, etc.
