Press-Fit Aluminum Electrolytic Capacitors ALF70, +85C Overview Applications The KEMET ALF70 Press-Fit capacitors eliminate the Typical applications for the ALF70 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 ALF70 High CV Press-Fit capacitors offer high performance and reliability in a wide range of case sizes and voltage ratings (up to 630 V), featuring high ripple currents and long-life performance. 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 ALF70 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 , I applied) Long life, up to 18,000 hours at +85C (V R R 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 ALF70 C 132 KP 600 Series Termination Capacitance Code (F) Size Code Rated Voltage (VDC) Press-Fit Type See Termination Table First two digits See Dimension Table 040 = 40 400 = 400 Aluminum Electrolytic r e p r e s e n t s i g n i fi c a n t 063 = 63 450 = 450 fi g u r e s .
