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.
