Type MPF, AC Motor Run Capacitors
Oval and Round, Oil Filled, 70 ºC, Metallized Polypropylene Capacitors
Type MPF AC metallized polypropylene film dielectric capacitors
offer a reliable option for alternating current applications. All
devices are oil filled in metal cases with 4-prong quick disconnect
terminals for easy assembly. These capacitors pack high
capacitance and voltage capabilities into a small, light-weight
package. The MPF is internally protected for fail-safe operation.
These capacitors have extremely low DF that is ideal for AC motor-
run applications.
