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.

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!
