Snubber capacitors

Home » Capacitors » Power Capacitors » Snubber capacitors

Snubber capacitors are double-sided metallized polypropylene film capacitors used in power conversion applications requiring stable capacitance and low dissipation factor to handle high voltage, high dV/dt and high ripple current.

Snubber capacitors Typical Applications:

• Silicon-controlled rectifier (SCR and IGBT)
and SiC (e.g. MOSFET) commutation circuits.
DC Link, Snubber, resonant converters, and
tank circuits.
