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.
Highlights
- Highest capacitance value
- Right for Power Supply and UPS systems
- Thermal-Pak extended cathode construction
