Type 944U Polypropylene, DC Link Capacitors
High Current, Low Profi le for Inverter Applications
Type 944U is specifi cally designed for use in high power DC
fi 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 fl exibility
in a rugged UL 94VO rated fl ame retardant plastic case and resin
fi ll. High current ratings and robust mounting fl anges make the
944U suited for inverter applications in electric vehicle power
inverters, wind power inverters and motor drives.
Highlights
- Low Inductance
