Cornell Dubilier Aluminum Electrolytic DCMC803U025AF2B

The DCMC series is a high-capacitance, screw-terminal aluminum electrolytic capacitor designed for power supply filtering and energy storage applications, with a rated voltage range of 6.3 Vdc to 550 Vdc and capacitance values from 110 µF to 2.7 F. It operates within a temperature range of -40 °C to +85 °C and features Thermal-Pak™ extended cathode construction for improved heat dissipation. The part DCMC803U025AF2B corresponds to an 80,000 µF capacitor at 25 Vdc with a case size of 1 3/8 inch diameter by 5 5/8 inch length, a high-post terminal, and an uninsulated can. Its maximum ESR at 120 Hz is 14.0 mΩ and maximum ripple current at 85 °C is 13.3 A. The series meets an endurance life test of 2000 hours at full load and 85 °C, with a capacitance tolerance of -10% to +75% for voltages ≤100 Vdc.
