Type 4CMC 85 ºC, High Cap, Plug-in, Radial Leaded Aluminum

Rugged Value, High-Capacitance 85 °C Board-Mount Type

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 fltering applications where

more capacitance or smaller can size is important like welders and

energy storage.  It delivers higher capacitance than the largest snap-

ins and Its heavy gauge can, molded high purity top and 14-gauge

reverse proof  3 copper pins provide better performance.

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
