West Coast Magnetics' 701 series base drive transformers are designed to operate from 10 kHz to 500 kHz. These base drive transformers provide 3000 Vac of isolation and a winding configuration which has consistent low leakage inductance qualities. These base drive transformers are available in through hole as well as surface mount packaging with tape and reel.
