Product Description
Product Description
Current Transformer Core Custom Design Silicon Steel FeSi Toroidal Core Split for Low Medium Voltage Instrument Transformer
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.
