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.
Highlights
w Latest available ratings, worldwide
w Top performance in power supplies and motor drives
w 4 times the life of Type 380L/LX
w Big selection of 46 case sizes
w 2, 4 and 5 leads available
