Electric Current Transformer Core

Electric Current Transformer Core
Performance characteristic: 
High permeability (smaller angle difference and the ratio difference), and compared to Permalloy higher saturation flux density, low loss, excellent temperature stability. 

Transformer cores for high frequency switch mode power supplies 
Current transformer cores for electric industry 
Transformer cores for ground-fault-interrupters 
Cores for filters, storage inductors, and reactors 
EMC common mode chokes 
Sensor cores 
Cores for saturable reactors, magnetic amplifiers, beads, and pulse compressors
