Cornell Dubilier Aluminum Electrolytic 401C344M7R5ED8

The Type 401C is a low-ESR aluminum electrolytic capacitor designed for high-ripple current applications in military and industrial environments, with operational capability from -55 °C to +105 °C. The 401C344M7R5ED8 variant has a capacitance of 340,000 µF, a rated voltage of 7.5 Vdc, and a maximum ESR of 7.8 mΩ at 25 °C and 5.6 mΩ at 20 kHz. It supports a ripple current of 25.0 A at 120 Hz and 27.8 A at 20 kHz. The capacitor uses a snap-in mounting style with case dimensions of 1 3/4 inches in diameter and 4 5/8 inches in height. It meets EIA IS-749 ripple life criteria for 2,000 hours at 85 °C and has a 4,000-hour life test at 105 °C. Thermal-Pak™ extended cathode construction ensures consistent heat dissipation in all orientations.
