Kmn1027625 King Magnetics Big Size Car Charger EMC Toroidal Nanocrystalline Core

Product Description

Product Description


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.
