Type 944U Polypropylene, DC Link Capacitors

High Current, Low Profile for Inverter Applications

Type 944U is specifically designed for use in high power DC

filtering applications. The low inductance internal construction

utilizes low loss metallized polypropylene for high ripple current

capability. Male or female terminal options offer design flexibility

in a rugged UL 94VO rated flame retardant plastic case and resin

fill. High current ratings and robust mounting flanges make the

944U suited for inverter applications in electric vehicle power

inverters, wind power inverters and motor drives.

Highlights

- Low Inductance

- Low Profile

- Low ESR

- High Ripple Current
