The ALS40/41 series of screw terminal

capacitors feature the same high ripple

currents and long life characteristics as the

ALS30/31 series but can operate at higher

temperatures. They are similarly 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.
