Type 4CMC 85 °C, High-Cap, Radial Leaded, Aluminum Electrolytic

Best Value Printed Circuit Mount Type

The Type 4CMC is the PC-mount version of the high-

capacitance 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 extended cathode foil assures cool

operation with heatﬂow from the capacitor element to

the can in all mounting orientations.

Highlights

• Much better value than large snap-in capacitor

• Ripple Currents to > 50 amps at 55 °C

• 3-leads for reverse proof, strong mounting

• Printed-circuit mounting version of DCMC

• Thermal-Pak™ extended cathode construction
