Film capacitors: Compact Motor Run Capacitors

TDK-EPC, a group company of the TDK Corporation, presents the EPCOS MotorCap™ DM series of highly compact motor run capacitors. The space-saving version is implemented in a new housing technology in which the capacitor windings are directly molded in plastic. This allows a significant reduction in capacitor dimensions: they are now between 24 x 43mm and 29 x 43mm (diameter x length). This corresponds to a volume reduction of up to 44 percent compared with conventional capacitors. In addition, the types of the MotorCap™ DM series are distinguished by their hermetically sealed housing. The new capacitors are designed for 250VAC with capacitances of 10 to 15 μF and for 450VAC with capacitances of 1.2 to 6μF. Their operating life is specified as 10,000 hours over the entire temperature range from -25 to +85°C. All types of the MotorCap™ DM series are available in safety classes P0 and P2 and are UL-approved. Their capacitor windings are self-healing. The components are available with fast-on terminals (B32318A*, B32358A*) or wire terminals (B32317A*, B32357A*). Capacitors of the new series are suitable for use in household appliances such as washing machines, dishwashers and refrigerators as well as in compressors, air-conditioners, pumps or awning drives. They can also be used as output filters of UPS installations. www.epcos.com/motorrun
