Cornell Dubilier Aluminum Electrolytic 101C553U020AC2B

The Type 101C is a low-ESR aluminum electrolytic capacitor designed for high-ripple current applications in military and industrial environments, operating from -55 °C to 105 °C. It features Thermal-Pak™ extended cathode construction for consistent heat dissipation in all orientations, a 5,000-hour load life at 105 °C, and ripple current capability exceeding 20.6 A at 85 °C. This specific variant, 101C553U020AC2B, is a 55,000 µF capacitor with a 200 Vdc rating, a capacitance tolerance of -10% to +75%, and an ESR of 12.2 mΩ at 25 °C. It has a case size of 1 3/8 inches diameter by 4 1/8 inches length, uses a high post terminal, and is designed for stud mounting with a 10-32 thread. The part achieves over 90% of its rated capacitance at -40 °C and meets the endurance test requirements under full load conditions.
