Nanocrystalline EMC Common Mode Choke Core Description
Nanocrystalline Cores feature very high permeability over wide frequency. They are very suitable for common mode choke to be used as an EMC filter to compress conducted common-mode noise. Compared to traditional ferrite core, Nanocrystalline EMC Common Mode Choke Core has a lot of advantages as high inductance, good filter effective, small size and volume less turn of copper wire, lower power consumption, and high efficiency. Permeability of our nanocrystalline core can reach 60000.
