Press-Fit Aluminum Electrolytic Capacitors ALF80, +105C Overview Applications The KEMET ALF80 Press-Fit capacitors eliminate the Typical applications for the ALF80 capacitor include need for solder, and therefore, the associated production inverters, frequency converters, motor drives, motor and quality issues. They are the next evolution of snap- control, UPS systems, smoothing, energy storage, in capacitors, providing reliable electrical contact and alternative energy, charging stations, traction, demanding the same vibration performance as soldered snap-in power supplies (SMPS), welding, and HVAC. terminals. The ALF80 High CV capacitors offer high performance and reliability in a wide range of case sizes and voltage ratings featuring high ripple currents and long-life per formance. Volumetric efficiency ensures the maximum capacitance capability in a smaller size. 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 In addition to solving the solder issues, the ALF80 Press-Fit offers: Maximum capacitance capability 35, 40, 45, and 50 mm diameters with 4 or 5 pin c on fi g u r a tion Long life, up to 9,000 hours at +105C (Vr, Ir applied) High ripple current Excellent surge voltage capability PET sleeve and Lexan disc are recognized to UL: QMTR2, UL No. E358957 (Other options available upon request) Optimized designs available upon request Part Number System ALF80 C 331 DF 500 Series Termination Capacitance Code (F) Size Code Rated Voltage (VDC) Press-Fit Type See Termination Table First two digits See Dimension Table 025 = 25 250 = 250 Aluminum Electrolytic r e p r e s e n t s i g n i fi c a n t 040 = 40 350 = 350 fi g u r e s .
