Type 944U Polypropylene, DC Link Capacitors
High Current, Low Pro le for Inverter Applications
Type 944U is speci cally designed for use in high power DC
ltering applications. The low inductance internal construction
utilizes low loss metallized polypropylene for high ripple current
capability. Male or female terminal options off er design exibility
in a rugged UL 94VO rated ame retardant plastic case and resin
ll. High current ratings and robust mounting anges make the
944U suited for inverter applications in electric vehicle power
inverters, wind power inverters and motor drives.
