Specications
Ratings
Type 944U is specically designed for use in medium power DC l-
tering applications. The low inductance internal construction utilizes
low loss metallized polypropylene for high ripple current capability.
Male or female terminal options offer design exibility in a rugged
UL 94VO rated ame retardant plastic case and resin ll.
