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.

Highlights

- Top performance in power supplies and motor drives

- 4 times the life of Type 380L/LX

- 2, 4 and 5 leads available

Speciﬁcations

- Big selection of 42 case sizes
