Cornell Dubilier Aluminum Electrolytic 500C174U025BF2B

The 500C174U025BF2B is a 95 °C long-life aluminum electrolytic capacitor with screw terminal mounting, designed for high-ripple applications in power supply and UPS systems. It has a capacitance of 170,000 µF, a rated voltage of 25 Vdc, and a case size of 2 inches diameter by 5 5/8 inches length. It is rated for 25.7 A ripple current at 85 °C and has an ESR of 6.1 mΩ at 25 °C. The capacitor operates within a temperature range of -40 °C to +95 °C and is qualified for 5000 hours of endurance testing at full load and 85 °C, with capacitance change within ±20% and ESR doubling allowed. Its thermal-pak extended cathode construction promotes efficient heat dissipation, and it supports stud-style mounting. No standards or qualifications beyond endurance and shelf life tests are cited.
