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
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).
