4CMC891M250AK8 Overview

High-Cap, Radial Leaded, Aluminum Electrolytic

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.
