Product Description

Kmn261610 Current Transducer Nanocrystalline Tape Split Strip Wound Toroidal Core



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 560ºC, much higher than traditional ferrite core about 200ºC. High curie temperature make nanocrystalline core excellent thermal stability, and can continuous working at up to 120ºC 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.
