Power Ring Film Capacitors
PRELIMINARY VERSION
Power Ring Film Capacitor™
400 µF, 450 Vdc
The 700A40794-204 Power Ring assembly
is a 400 µF, 450 Vdc dual-winding DC Link
Capacitor integrated with a laminar bus.
The assembly has an ESR of 440 μω
at
20 kHz, an ESL less than 8 nH, and a life of
more than 10,000 hours at a typical drive cycle
for an 80-120 kW inverter.
