ELG Aluminum Electrolytic Snap-in Capacitors KEMET ELG Series Snap-in Capacitors are compact, high ripple current snap-in capacitors with excellent surge voltage capability. The KEMET ELG Series Snap-in Capacitors offer long life - for 2000 hrs @ 105ºC - and are suited for high reliability and long life applications such as frequency converters, UPS systems, and switch mode power supplies, but the extended temperature range allows increased ripple currents at lower temperatures.
