Overview

The KEMET ALF20 Press-Fit capacitors eliminate the

need for solder, and therefore, the associated production

and quality issues. They are the next evolution of snap-in

capacitors, providing reliable electrical contact and the

same vibration performance as soldered snap-in terminals.

The ALF20 offers high voltages up to 600 VDC, high ripple

currents, good surge voltage capability, and a very long life

performance.

Applications

The KEMET ALF20 capacitors are ideally suited for

industrial and commercial applications, demanding high

reliability and long life expectancy. Typical applications

include frequency converters, advanced energy storage

systems, and switch mode power supplies (SMPS).

Press-Fit Aluminum Electrolytic Capacitors – ALF20, +85ºC Shelf Life The capacitance, ESR and impedance of a capacitor will not change significantly after extended storage periods, however, the leakage current will very slowly increase. KEMET products are particularly stable and allow a shelf life in excess of three years at 40°C. See sectional specification under each product for specific data.

Press-Fit Aluminum Electrolytic Capacitors – ALF20, +85ºC MEAN TIME BETWEEN FAILURES The mean time between failures (MTBF) is simply the inverse of the failure rate. MTBF = 1/λ Failure Rate early failures wear out operational life Time The failure rate is derived from our periodic test results. The failure rate (λR) is, therefore, only given at test temperature for life tests. An estimation is also given at 40°C.

Press-Fit Aluminum Electrolytic Capacitors – ALF20, +85ºC Mechanical Data Polarity & Reversed Voltage Aluminium electrolytic capacitors manufactured for use in DC applications contain an anode foil and a cathode foil. As such, they are polarized devices and must be connected with the +ve to the anode foil and the -ve to the cathode foil.

Press-Fit Aluminum Electrolytic Capacitors – ALF20, +85ºC Construction Data The manufacturing process begins with the anode foil being electrochemically etched to increase the surface area and then “formed” to produce the aluminum oxide layer. Both the anode and cathode foils are then interleaved with absorbent paper and wound into a cylinder. During the winding process, aluminum tabs are attached to each foil to provide the electrical contact.
