Cornell Dubilier Aluminum Electrolytic 101C543U020BH2B

The 101C series is a low-ESR, wide-temperature aluminum electrolytic capacitor designed for high-ripple current military and industrial applications, operating from -55 °C to +105 °C. It features a Thermal-Pak™ extended cathode construction to ensure consistent heat dissipation in all mounting orientations. This part operates at 20 Vdc with a capacitance of 54,000 µF, a maximum ESR of 13.0 mΩ at 25 °C, and a rated ripple current of 18.0 A at 85 °C. It is mounted in a 2-inch diameter by 2 5/8-inch length case with a high post terminal. The capacitor has a 5,000-hour load life at 105 °C and maintains over 90% capacitance at -40 °C.
