Specifications

Stored inductance made of amorphous is widely used in DC-DC inverter, filtering resonance suppressor, DM inductor, etc. It can reach the constant inductance property and anti superimposed DC bias capability through zero air gap or open air gap, and the loss is small . It' s mainly used in the anti-direct current filtering
and choking coils in auto audio system, filtering inductance in power supply, smoothing inductor, stored inductance, differential mode inductance, PFC correction Inductor, etc.
 
Applications :
 
▲ Application in the anti-direct current filtering and choking coils in auto audio system , filtering inductance in power supply.
▲ Application in smoothing inductor, stored inductance, differential mode inductance, PFC Correction
Inductor, etc.
 
Properties :
 
▲ Made of Fe-based amorphous ribbon, low loss in high frequency.
▲ Magnetic circuit closing, reduction of flux leakage, excellent characteristics of anti-DC current skewing of magnetic field.
▲ High permeability, to be adjusted by changing the winding turns.
