The MSC Series is a range of AC electrolytic capacitors. These capacitors are most often used to provide the torque necessary to start AC motors and in other intermittent AC applications.
Vertical mounting of the capacitor with the terminals up is recommended. However, horizontal mounting is acceptable providing the vent is located in the up position. Vertical mounting with the terminals down is not recommended because the capacitor life may be reduced and the operation of the pressure relief vent impaired.
Solvent residues on the capacitors after cleaning may penetrate the seal and cause internal corrosion resulting in shortened life. Alcohol or water detergent cleaning is not usually harmful but halogenated cleaning solvents are not recommended and should be avoided.
Because the watt-second value of these capacitors is high, precautions should be taken during the testing of these devices. Discharge resistors should be specified when there is a possibility of a residual charge left on the capacitor or to protect contacts. Mis-application, such as exceeding the design limits or applying continuos AC voltage, may result in destruction or explosion of capacitors.
