Types 381L, 383L, 381LX & 383LX, 105 C High-Ripple Snap-In Types 381L/LX & 4-pin Mount 383LX (105 C) Adding longer-life and more ripple capability to the excel- lent value of Type 380L/LX capacitors, the 381L/LX readily handles tough switching power supply input and output circuits and motor-drive bus capacitor applications where the high surface area of multiple units in parallel equals the ripple capability of our Type 520C inverter-grade capacitor. Type 381LX delivers more capacitance per can size while Type 381L gives lower ESR for the same capacitance rating. Type 383L gives the choice of 4 or 5 leads for stable, reverseproof mounting. Type 383LX has 5 leads available.
