381LR271M400K032 is a 270 µF, 400 Vdc snap-in aluminum electrolytic capacitor from Cornell Dubilier's Type 381LR series, designed for ultra-high ripple current applications. It features a maximum ESR of 0.737 ohms at 120 Hz and 0.332 ohms at 20 kHz, with ripple current ratings of 1.22 A at 120 Hz and 1.71 A at 20 kHz at 105°C. The capacitor operates over a temperature range of -25°C to +105°C and has a nominal size of 30 x 30 mm with ±20% capacitance tolerance. With an endurance life of 3000 hours at full load at 105°C and extremely low ESR values, this capacitor is ideal for motor drive bus capacitors and UPS bus capacitors where high ripple current handling is critical.
