AC Motor Start Aluminum Electrolytic Capacitors MS/MD Series, +60C/+70C Overview Applications KEMET s MS/MD Series of aluminum electrolytic capacitors are KEMET s MS/MD Series is a range of aluminium electrolytic designed for itermittent duty only and capable of withstanding capacitors specifically designed for AC operation which helps the AC voltage applied to the motor during starting. The to start the motor by providing a leading current to the auxiliary capacitor construction is comprised of either double anode or winding. The capacitor is not permanently connected to the O-style (double anode and floating cathode) windings, which winding of the motor and is usually switched off automatically are housed in a molded plastic case. KEMET s MD Series is after starting. VDE approved to IEC 60252-2 for the defined ratings. Benefits Intermittent AC motor starting 6.3 mm double amp tags (quick connect types) VDE approved to IEC 602522 Part Number System 080 MS 12 AA M A 1 STD Capacitance Code Manufacturing Capacitance Rating Voltage (VAC) Size Code Terminal Code Version (F) Style Tolerance Example: MS = Motor start 12 = 120 See Dimension M = Molded case A = -0% +25% 1 = Double amp STD = Standard 080 = 80 F single rating 22 = 220 Table K = 10% tag 120 = 120 F MD = Motor start 26 = 260 dual rating One world.
