About Snubber Capacitor 3uf 1000V DEC

DEC PPB-SNB(L) Snubber Film Capacitor (3F, 1000V DC)

Description: The DEC PPB-SNB(L) is a high-voltage, polypropylene film snubber capacitor engineered specifically for protecting power semiconductors from damaging voltage spikes. With a capacitance of 3F and a high working voltage of 1000V DC, it features an exceptionally low self-inductance and low equivalent series resistance , enabling it to handle high peak currents ($dV/dt$) seamlessly. Encapsulated in a compact, flame-retardant box housing, it is equipped with heavy-duty, short slotted lug terminals designed for direct, low-inductance mounting onto IGBT modules or busbars.
