Type SCD IGBT Snubber Capacitor Modules Direct Mount Snubber Capacitor Applications Style SCD offers protection against voltage transients in low to medium current IGBT applications where high dV/dt is encountered. Connect these capacitors from C1 to E2 on a dual IGBT module or from P to N on a six-pack module to eliminate severe voltage transients. Parts ending with Z25 fit IGBTs with 23mm, 25mm and 28mm lead spacing. If you have a preferred lead spacing, please specify. Specifications Highlights • • • • • • • High peak & RMS current capability Mount directly to the IGBT module Low inductance <20nH Low loss polypropylene dielectric Self healing Flame resistant case and resin, meets UL94V0 Other terminal spacing and capacitance values available. We can build to your specs! • 85°C ambient temperature Ratings Complies with the EU Directive 2002/95/EC requirement restricting the use of Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent chromium (Cr(VI)), PolyBrominated Biphenyls (PBB) and PolyBrominated Diphenyl Ethers (PBDE).
