Type 381LX / 383LX 105 °C High Ripple, Snap-In Aluminum
High Ripple, Long Life, 2, 4 and 5 pin styles available
Adding longer-life and more ripple capability to the excellent
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/LX has 4 or 5 leads for stable,
reverse-proof mounting.
