GTO snubber capacitor is in non-inductive structure and has the terminal leads of copper nuts. This industrial capacitor is wrapped with PET adhesive tape and enveloped with flame-resistant epoxy resin.

Our damper capacitor has strong over-current, low ESL, high peak current, easy installation and superb resistance to high voltage. This metallized film capacitor is excellently used as snubber capacitor to buffer the high frequency ripple wave and peak voltage for GTO in the high power thyristor.
