SN Coils

KEMET SN Coils are differential mode coils with a wide variety of characteristics. These coils feature proprietary Fe dust cores that are ideal for normal mode noise countermeasures. KEMET SN Coils offer a rated current AC range from 500mA to 20A and a rated inductance range from 1.5µH to 550µH. Typical applications include home appliances and power supplies.
