www.DataSheet4U.com ALS30 Series 85°C RoHS Compliant • Compact size • Long life, 20000 hours at 85°C (Ur, Ir applied) • High ripple current • Excellent surge voltage capability • Optimized designs available on request application Smoothing, energy storage, or pulse operation in telecommunication demanding power supplies, process control, AC-motor control, traction, welding and measuring. Basic design The ALS30/31 series of screw terminal capacitors cover a wide range of case sizes and voltage ratings featuring high ripple currents and long life performance. They are ideally suited for industrial and commercial applications demanding high reliability and long life expectancy such as frequency converters, UPS systems and switch mode power supplies.
