ALS40 Series 105°C• Compact Size• Long Life, 9000 hours at 105°C (Ur, Ir applied)• High ripple current• Excellent surge voltage capability• Optimized designs available on requestRoHSCompliantapplicationBasic designSmoothing, energy storage, or pulse operationin telecommunication demanding powersupplies, process control, AC-motor control,traction, welding and measuring.The ALS40/41 series of screw terminalcapacitors feature the same high ripplecurrents and long life characteristics as theALS30/31 series but can operate at highertemperatures. They are similarly suited forhigh reliability and long life applicationssuch as frequency converters, UPSsystems and switch mode power supplies,but the extended temperature rangeallows increased ripple currents at lowertemperatures.SpecificationStandards IEC 60384-4 Long Life Grade 40/85/56,Capacitance range 150 – 680000 µFCapacitance tolerance –20 to +20%Rated voltage U RSurge voltage U S25–450 VDC1.15 x U R(for U R< 250 VDC)1.10 x U R(for U R> 350 VDC)Test Condition:< 30s surge, 1000 cycles @ 105°CSurge voltage U SS(Short duration)Leakage current I LOperational life time+105°C, U R, I RU RU SS200 350250 400350 500400 520415 530450 550500 600= 0.003 x C Rx U R(µA) or 6mA whicheveris the smaller.
