Screw Terminal Aluminum Electrolytic Capacitors ALS80/81, High CV, +105C Overview Applications KEMET s ALS80/81 high CV screw terminal capacitors Typical applications for KEMET s ALS80/81 series of features the same high ripple currents and long life capacitors include alternative energy, smoothing, energy characteristics as the ALS70/71 series, but can operate storage or pulse operation in telecommunication demanding at higher temperatures. Volumetric efficiency ensures the power supplies, process control, AC motor control, traction, maximum capacitance capability in a smaller size. They are welding, and measuring. similarly suited for high reliability and long life applications such as frequency converters, uninterruptible power supply (UPS) systems, and switch mode power supplies (SMPS). The extended temperature range allows increased ripple currents at lower temperatures. Benefits Maximum capacitance capability in a smaller size , I applied) Long life, up to 9,000 hours at +105C (V R R High ripple current Excellent surge voltage capability PET sleeve recognized to UL QMTR2, UL No. E358957 (Other options available upon request) Optimized designs available upon request Part Number System ALS8 0 A 303 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.
