Type DCMC 85 °C High Capacitance, Screw Terminal, Aluminum

Highest Capacitance Screw Terminal Type

With more capacitance and often more ripple-current capabilty than

the best-value Type 3186 capacitor, the Type DCMC capacitor is the

better choice for high-capacitance, power supply filters and energy

storage applications such as welding equipment,UPS systems and

computer hold-up power. The extended cathode foil of the DCMC

assures cool operation with heatflow from the capacitor element to

the can.
