Press-Fit Aluminum Electrolytic Capacitors
ALF40, +105°C
Overview
Applications
TheꢀKEMETꢀALF40ꢀpress-fitꢀcapacitorsꢀeliminateꢀtheꢀ
need for solder, 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. These
capacitors cover a wide range of case sizes and voltage
ratings. The ALF40 offers high voltages up to 500 VDC,
high ripple currents, good surge voltage capability, and a
very long life performance. Rated operating temperature
is 105°C.
TheꢀALF40ꢀpress-fitꢀcapacitorsꢀareꢀsuitedꢀforꢀhighꢀ
reliability and long life applications, such as frequency
converters, solar inverters, advanced energy storage
systems, and switch mode power supplies (SMPS). The
extended temperature range allows increased ripple
currents at lower temperatures.
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
