Cornell Dubilier Poly Film Caps 944U

Polypropylene Film Capacitors Type 944U

The Cornell Dubilier 944U Type Polypropylene Film Capacitors are specifically designed for use in medium power DC filtering applications. The low inductance internal construction utilizes low loss metallized polypropylene for high ripple current capability. With capacitance ranges between 33 and 220 µF and voltage ranges between 800 Vdc to 1400 Vdc, the Cornell Dubilier 944U Film Capacitors are offered in male or female terminals for design flexibility in a rugged UL 94VØ rated flame retardant plastic case and resin fill. The 944U Type Polypropylene Film Capacitors are ideal for the DC link in inverters and for DC output filters .
