Product Description

Product Description

Ferrite Core Technology for Reliable Stator and Toroidal Systems
Silicon Steel Toroidal transformer core 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.

Saturation flux density induction: 1.25T 
Permeability @ 10KHz: 80000
Permeability @ 100KHz: 20000
Curie temperature(ºC): 560 
Stacking factor: 0.78 
Saturation magnetostriction(*10^-6): <2 
Resistivity (μΩ.cm): 115 
Ribbon thickness: 25μm 
Core shapes: Troidal core
