Nanocrystalline Core for Common Mode Choke
Thanks for the development of amorphous and nanocrystalline technology, which is a very important technology in modem magnetic materials, cores and inductive components. King Magnetics has developed series of nanocrystalline cores for common mode chokes.
Nanocrystalline cores have very high permeability over low frequency to high frequency up to 30Mhz. They are very suitable for common mode choke to 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, lower turns of copper wire, lower power consumption and high efficiency.
Nanocrystalline cores have high curie temperature 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 for application of common mode choke.
