## **Typical applications** 

Switch-mode power applications DC/DC converters HVAC, typically in EMI input filter for ventilation LED driver circuit 

For suppression-equipment with no earth connection, e.g. medical Phase-angle control circuits in combination with saturating chokes Consumer electronics, EDP, test equipment, electronic ballasts in lamps etc. 

Applicable for low frequency signaling effective from 10kHz to 30MHz
