Screw Terminal Aluminum Electrolytic Capacitors
ALS36/37, +85°C
Overview
Applications
KEMET's ALS36/37 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.

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.
