These Run Capacitors are designed specifically for Appliances , Motors , HVAC Equipment , Compressor , Office Equipment and Other Applications where Run capacitors are used in conjunction with Permanent Split capacitor type motors and/or compressors. Standard configurations of single round, single oval, double round, and double oval are also available (sold separately). These capacitors use a special film that allows the manufacturing process to create smaller capacitors and still have a long life performance even though the parts are much smaller. These capacitors are on the leading edge of capacitor design and the smaller case products will match or exceed the reliability of the previous designs.
