Type 400C, 95 °C, Long-Life, Computer Grade, Radial Leaded
Twice the Life!
The Type 400C is the PC-mount equivalent for Type 500C
screw-terminal computergrade capacitor. It’s for bus filtering
applications where long life is critical like telecom systems
and industrial power supplies. Type 400C delivers 2 to 3
times the life of Type 4CMC, and above 250 V it has nearly
the same capacitance. Its extended cathode foil assures cool
operation with heatflow from the capacitor element to the
can in all mounting orientations.
Highlights
ꢀ More than 10 years life in most applications
ꢀ Ripple Currents to > 50 amps at 55 °C
ꢀ 3-leads
ꢀ Printed-circuit mounting
ꢀ Thermal-PakTM extended cathode construction
