Screw Terminal Aluminum Electrolytic Capacitors
ALS40/41, +105C
Overview Applications
KEMET's ALS40/41 Series of screw terminal capacitors Typical applications for KEMET's ALS40/41 capacitors
features the same high ripple currents and long-life include smoothing, energy storage or pulse operation in
characteristics as the ALS30/31 Series but can operate telecommunication demanding power supplies, process
at higher temperatures. They are similarly suited for high control, frequency inverters, drives, traction, welding, and
reliability and long-life applications such as frequency measuring.
converters, uninterruptible power supply (UPS) systems,
and switch mode power supplies (SMPS) but the extended
temperature range allows increased ripple currents at lower
temperatures.
