power line choke coils and transformers high frequency ferrite nanocrystalline cores

Amorphous and nanocrystalline technology is a very important technology in modern magnetic materials, cores and inductive components. King Magnetics has developed series of nanocrystalline cores for common mode chokes.

Nanocrystalline cores feature very high permeability over low frequency to high frequency up to 30Mhz. They are very suitable for common mode choke to be used as EMC filter to compress conducted common mode noise. Compared to traditional ferrite core, nanocrystalline core has a lot of advantages as high inductance, good filter effective, small size and volume, less turns of copper wire, lower power consumption and high efficiency.

Curie temperature of nanocrystalline cores is about 560℃, much higher than traditional ferrite core about 200℃. High curie temperature make nanocrystalline core excellent thermal stability, and can continuous working at up to 120℃ environment.

Nanocrystalline cores is the best choice soft magnetic material for common mode choke. Our nanocrystalline cores used 25μm thickness second generation thin ribbons, which have much higher permeability at high frequency.
