Press-Fit Aluminum Electrolytic Capacitors ALF20, +85C Overview Applications The KEME T ALF20 press-fit capacitors eliminate the The ALF20 capacitors are ideally suited for industrial need for solder, and therefore, the associated production and commercial applications, demanding high reliability and quality issues. They are the next evolution of snap- and long life expectancy. Typical applications include in capacitors, providing reliable electrical contact and frequency converters, advanced energy storage systems, the same vibration performance as soldered snap-in and switch mode power supplies (SMPS). terminals. The ALF20 offers high voltages up to 600 VDC, high ripple currents, good surge voltage capability, and a very long life performance. Benefits Eliminates the manufacturing problems of soldering onto thick PCB copper tracks which act as heat-sinks Eliminates fractured solder joints/cold-solder Skipping the solder operation allows for easy insertion after the production washing process C a pa b ili t y to e xc ha n g e c o m p o n e n t s i n th e fi e l d I n a d di ti o n to s o l v i n g th e s o l d e r is su es , th e A L F 2 0 p r es s - fi t offers: Compact size , I applied) Long life, up to 18,000 hours at +85C (V R R High ripple current High voltage up to 600 V Excellent surge voltage capability 35, 40, 45, and 50 mm diameters with 4 or 5 pin c on fi g u r a tion Optimized designs available upon request Part Number System ALF20 C 392 EF 040 Series Termination Capacitance Code (F) Size Code Rated Voltage (VDC) Press-Fit See Termination Table First two digits See Dimension Table 035 = 35 350 = 350 Aluminum r e p r e s e n t s i g n i fi c a n t 040 = 40 400 = 400 Electrolytic fi g u r e s .
