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.
Highlights
- Low DF
- Protected with a pressure sensitive interrupter
- Small size and light weight
- UL E71645
- CSA 219950
- Air conditioning and refrigeration applications
- Power factor correction
- Motors

The service life objective for this series is 60,000 hours of
operating life with a 94% survival rate when operated at
full voltage, 60 Hz, and rated ambient temperature. AC ca-
pacitors are frequently used at voltages and ambient tem-
peratures other than rated conditions. Service life may be
estimated under specific conditions of temperature and
voltage by using the curves as shown below and to the
right.
Service Life Objective
Capacitance vs. Temperature
The Capacitance vs. Temperature curve may be used to determine
the capacitance change as a function of temperature. Capacitance
varies by no more than ±3% over the operating temperature range.
