Types 381L, 383L, 381LX & 383LX 105 ºC High-Ripple Snap-In
2-pin Types: 381L and 381LX. 4-pin or 5-pin Types: 383L and 383LX
Adding longer-life and more ripple capability to the excellent val-
ue 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 mount-
ing. Type 383LX has 5 leads available.
