Type 400C

95 °C, Long-Life, C Radial Leaded, Aluminum Electrolytic

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.
