Screw Terminal Aluminum Electrolytic Capacitors
ALS80/81, High CV, +105°C
Overview
Applications
Typical applications for KEMET's ALS80/81 series of
capacitors include alternative energy, smoothing, energy
storage or pulse operation in telecommunication demanding
power supplies, process control, AC motor control, traction,
welding and measuring.
KEMET's ALS80/81 high CV screw terminal capacitors
features the same high ripple currents and long life
characteristics as the ALS70/71 series, but can operate
at higher temperatures. Volumetric efficiency ensures the
maximum capacitance capability in a smaller size. They are
similarly suited for high reliability and long life applications
such as frequency converters, uninterruptible power supply
(UPS) systems, and switch mode power supplies (SMPS).
The extended temperature range allows increased ripple
currents at lower temperatures.
Benefits
• Maximum capacitance capability in a smaller size
• Long life, up to 9,000 hours at +105°C (Vr, Ir applied)
• High ripple current
• Excellent surge voltage capability
• PET sleeve recognized to UL QMTR2, UL No. E358957
• Optimized designs available upon request

Case Polarity
Due to the presence of electrolyte in the capacitor, the aluminum can and stud mounting will essentially be at the same
polarity as the negative terminal. We recommend that the stud and can be insulated (see accessories for insulating nuts).
Terminations
Aluminum inserts with M5 threads as standard, have a maximum torque 2NM. Optional M6 threaded inserts have a
maximum torque 4NM. Maximum torque for stud mounting M8:4NM and M12:8NM.
