381LR471M450A052 is a 470 µF, 450 Vdc snap-in aluminum electrolytic capacitor from Cornell Dubilier's Type 381LR series, designed for ultra-high ripple current applications. It features an extremely low ESR of 0.282 ohms at 120 Hz and 0.127 ohms at 20 kHz, enabling ripple current ratings of 2.47 A at 120 Hz and 3.53 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 35 x 50 mm with 4.0 mm pin length. With a 3000-hour endurance life at full load and 105°C, this capacitor is ideal for motor drive bus capacitors and UPS bus capacitors where high ripple current handling and reliability are essential.
