The Type 401C is a low-ESR aluminum electrolytic capacitor designed for high-ripple current applications requiring full performance from -55 °C to 105 °C. The 401C304M7R5BJ8 variant has a capacitance of 300,000 µF, a rated voltage of 7.5 Vdc, and a case code BJ with dimensions 2.00 in diameter by 3.50 in length. It exhibits a maximum ESR of 6.5 mΩ at 120 Hz and 4.9 mΩ at 20 kHz, with a ripple current rating of 26.6 A at 25 °C and 28.8 A at 85 °C. Its thermal-pak extended cathode construction ensures stable operation across all mounting orientations. The capacitor meets EIA IS-749 for 2,000 hours at 85 °C and sustains 4,000 hours at 105 °C under rated voltage. Capacitance tolerance is ±20%.
