Press-Fit Aluminum Electrolytic Capacitors
ALF80, +105°C
Overview
Applications
The KEMET ALF80 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 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-lifeꢀperformance.ꢀVolumetricꢀefficiencyꢀensuresꢀtheꢀ
maximum capacitance capability in a smaller size.
Typical applications for the ALF80 capacitor include
inverters, frequency converters, motor drives, motor
control, UPS systems, smoothing, energy storage,
alternative energy, charging stations, traction, demanding
power supplies (SMPS), welding, and HVAC.
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
•ꢀ Capabilityꢀtoꢀexchangeꢀcomponentsꢀinꢀtheꢀfield
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
configuration
• Long life, up to 9,000 hours at +105°C (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
