AC Motor Start Aluminum Electrolytic Capacitors MS/MD, +60C/+70C Overview Applications KEMET s MS/MD Series of aluminum electrolytic KEMET s MS/MD capacitors are a range of aluminium capacitors are designed for intermittent duty only and electrolytic capacitors specifically designed for AC capable of withstanding the AC voltage applied to the operation which helps to start the motor by providing a motor during starting. The capacitor construction is leading current to the auxiliary winding. The capacitor is comprised of either double anode or O-style (double anode not permanently connected to the winding of the motor and and floating cathode) windings, which are housed in a is usually switched off automatically after starting. molded plastic case. KEMET s MD Series is VDE approved to IEC 602522 for the defined ratings.

Valid for intermediate capacitance. Values in increments of 1 F between 30 F and 100 F, and in increments of 5 F between 100 F and 125 F. Approved duty cycles relate to 50 Hz, as per section 3.1.12.2 of IEC602522 operation at 60 Hz is also approved if the relative operation time is reduced by 20%. For example a 50 Hz duty cycle with ED = 1.7% is also approved for 60 Hz with ED = 1.36%.
