Cornell Dubilier Aluminum Electrolytic 500C424U025DF2D

The Type 500C aluminum electrolytic capacitor with part number 500C424U025DF2D is a screw terminal type designed for long-life applications in UPS and power supply filtering. It has a capacitance of 420,000 µF, a rated voltage of 25 Vdc, and operates within a temperature range of -40 °C to +95 °C. The capacitor measures 3 inches in diameter and 5 5/8 inches in length, with a high post terminal and standard can style. It exhibits a maximum ESR of 3.2 mΩ at 25 °C and a maximum ripple current of 44.9 A at 85 °C. The part undergoes a 5000-hour endurance test at full load and 85 °C, with a capacitance change of ±20% and ESR doubling as limits. Thermal-Pak™ extended cathode construction ensures cool operation.
