Cornell Dubilier Aluminum Electrolytic 101C773U020BB2B

The Type 101C is a low-ESR aluminum electrolytic capacitor designed for wide-temperature operation from -55 °C to +105 °C, suitable for high-ripple current applications in military and industrial power supplies. It features thermal-pak construction with an extended cathode foil for improved heat dissipation in all mounting orientations. The part 101C773U020BB2B has a capacitance of 77,000 µF, a rated voltage of 20 Vdc, a case code of BB (2 inch diameter by 3 1/8 inch length), a high post terminal, and a standard can style. Its maximum ESR at 25 °C is 8.6 mΩ, and it supports a ripple current of 23.4 A at 85 °C. The capacitor exhibits >90% capacitance retention at -40 °C, meets a 5,000-hour load life test at 105 °C under full load, and complies with the listed dimensional specifications for its case size.
