–40 °C to +85 °C, High Capacitance
Type DCMC
85 ºC 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 capaci-
tor 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 ca-
pacitor element to the can.
