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!
- 85°C ambient temperature
