Introduction:
Hemei Electronics specializes in the research, development, production and sales of high quality amorphous magnetic rings, nanocrystalline magnetic cores, ultramicrocrystalline iron cores and high performance magnetic components. With advanced production equipment and technology, our amorphous magnetic cores, nanocrystalline magnetic cores and components products have high performance, good stability and consistency. Our main amorphous and nanocrystalline magnetic core products are made of high quality strips, the manufactured nanocrystalline cores have high permeability, better frequency characteristics, low loss, and are suitable for high-frequency inverter transformers, common-mode filtering inductors and so on used in high-frequency occasions.
Material Characteristics:
> High permeability -- increase inductance and reduce the number of winding turns.
> High saturation magnetic induction -- reduces device size
> High frequency capability -- 50Hz - 100KHz frequency range
> High Curie Temperature -- High operating temperature, continuous operation up to 120℃.
> Low Coercivity -- improves efficiency and reduces hysteresis losses
> Low Loss -- energy efficient, low temperature rise
> Low magnetostrictive coefficient -- low noise compared to conventional magnetic materials
> Excellent thermal stability -- low deviation in performance over a wide temperature range of -20°C to 120°C
> Low cost -- cost-effective relative to Permalloys, allowing for substitution.
