Type SCD IGBT Snubber Capacitor Modules
High dV/dt Direct Mount IGBT Snubber
Style SCD oers 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 t 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
- Low loss polypropylene dielectric
- Self healing
- Other terminal spacing and capacitance values available.
- We can build to your specs!
- 85 °C ambient temperature
