Type 381LQ 105 °C Compact, High-Ripple Snap-in

23% Smaller for Same Capacitance

Type 381LQ is on average 23% smaller and more than 5 mm

shorter than Type 381LX. This is achieved with a new can

closure method that permits installing capacitor elements into

smaller cans. Approaching the robust capability of the 381L

the new 381LQ enables you to shrink equipment size and

retain the original performance.

Highlights

•

New, more capacitance per case
