Capacitors are rated in microfarad (mf) and provide the surge of excess voltage to start motors or for running it. These can be used for either 110 or 220 volt motors.
Generically speaking the higher mf are more suitable for 115V application (example 20 and higher)
Check rating of yours mf rating before ordering, different motors have different ratings/capacitor
