Type 381LQ 105 °C Compact, High-Ripple Snap-in
23% Smaller for Same Capacitance
Highlights
♦ New, more capacitance per case
♦ Compare to Type 381L
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.
