DCMC681T450AC2B is a Type DCMC high-capacitance aluminum electrolytic capacitor with screw terminals, rated for 450 Vdc (500 Vdc surge) operation. This capacitor features a 680 µF capacitance with an ESR maximum of 228.4 mO at 25°C and a ripple current capability of 2.9 A at 85°C, housed in a 2 × 2 1/8 inch package. The extended cathode foil construction (Thermal-Pak™) ensures efficient heat dissipation and cool operation, making it ideal for high-capacitance power supply filters, UPS systems, and energy storage applications such as welding equipment. Its combination of high capacitance, low ESR, and robust thermal design provides superior performance in demanding industrial and power conversion environments.
