Amorphous powder core 

With the continuous advancement of electronic power and information industry technology, the requirements for electronic and communication equipment and their components are constantly developing in the direction of miniaturization, high frequency and high current. The magnetic powder core is a composite soft magnetic material made by mixing ferromagnetic powder and insulating adhesive. Due to the small particle size of the magnetic powder, it is not easy to form the skin effect, and the surface of the magnetic powder is covered with a layer of insulating dielectric film. The magnetic powder core has high resistivity and low eddy current loss, and is suitable for medium and high frequency (20KHz-1MHz) applications. Widely used in green lighting, inductors and coils of electronic products, communication components and high-frequency micro-magnetic devices. Compared with conventional metal magnetic powder cores (FeSi, Sendust, etc.), magnetic powder cores based on iron-based amorphous materials have both high saturation magnetic induction (1.45T~1.56 T), excellent DC bias characteristics, low high-frequency loss, high It has the characteristics of strength and high corrosion resistance, and has good comprehensive performance. It has been widely used in the electronics and information technology industries.
