Polypropylene films down to about 1.9 μm are commercially available. Over time, a tailor made technology evolved for the production of capacitor-grade polypropylene resins. These are now produced in special polymerization plants where catalyst residues from the polymerization process are deactivated and removed from the polymer [3].
The 5MPA SERIES represents an excellent solution for AC motor run applications where high PWM and other feedback currents are present on top of line frequency. The 5MPA is superior to other brands. This is due to its unique high current and frequency response terminations, plus a dry film construction. Additional Information

Film capacitors are made out of two pieces of plastic film covered with metallic electrodes, wound into a cylindrical shaped winding, with terminals attached, and then encapsulated. In general, film capacitors are not polarized, so the two terminals are interchangeable. There are two different types of plastic film capacitors, made with two different electrode configurations:
