Type 4CMC 85 °C, High-Cap, Computer Grade, Radial Leaded
Best Value Printed Circuit Mount Type
The Type 4CMC is the PC-mount version of the high-capac-
itance Type DCMC screw-terminal capacitor and has about
50% more capacitance per can size through 250 V. It’s for
bus filtering applications where more capacitance or smaller
can size is important like welders and energy storage. It’s a
much better value than a large snap-in capacitor. Its extend-
ed cathode foil assures cool operation with heatflow from
the capacitor element to the can in all mounting orientations.
