Screw Terminal Aluminum Electrolytic Capacitors
ALS32/33 Series, +85°C
Overview
Applications
KEMET's ALS32/33 Series of capacitors is designed for industrial
and commercial applications such as switch mode power
supplies (SMPS), uninterruptible power supply (UPS) systems,
variable speed drives, frequency inverters, welding equipment,
and energy storage in pulse discharge applications.
KEMET's ALS32/33 Series of screw terminal capacitors meets
the requirements of the Asian market. This range offers high CV
per unit volume coupled with high ripple currents and long-life
performance.

Polarity Mark
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, maximum torque 2NM. Optional M6 threaded inserts have a maximum torque 4NM.
Maximum torque for stud mounting M8:4NM and M12:8NM.
