The EPCOS MotorCap DM (direct mold) Series of motor run capacitors is implemented in a new housing technology in which the capacitor windings are directly molded in plastic, allowing a reduction in capacitor dimensions to between 24 mm x 43 mm and 29mm x 43 mm (diameter x length). This corresponds to a volume reduction of up to 44 percent compared with conventional capacitors, according to the company In addition, types in the MotorCap DM series are distinguished by their hermetically sealed housing. The new capacitors are designed for 250 V AC with capacitances of 10 uF to 15 µF and for 450 V AC with capacitances of 1.2 uFto 6 µF. Their operating life is specified as 10,000 hours over the entire temperature range from -25 to +85 C. Capacitors in this 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.
