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. Benefits Compact size , I applied) Long life, up to 9,000 hours at +105C (V R R High ripple current Excellent surge voltage capability Optimized designs available upon request Part Number System ALS4 0 A 153 DA 025 Capacitance Code Series Stud Option Termination Size Code Rated Voltage (VDC) (F) Screw Terminal 0 = Plain can See Termination First two digits See Dimension 025 = 25 250 = 250 Aluminum 1 = Threaded Table represent Table 040 = 40 350 = 350 Electrolytic mounting stud significant 063 = 63 400 = 400 figures.
