### Replacing Capacitors With Different Values Guide

Capacitance, or capacitance rating, is the amount of energy that can be stored in the capacitor. The higher the capacitance rating, the more energy that can be stored. Generally speaking, you should always replace like-for-like when it comes to capacitors – meaning if your capacitor has a capacitance rating of 10μF, you should …

For most standard motors, a run capacitor will have a "tolerance" specified describing how close to the rated capacitance value that the actual value may be. This will be usually +/- 5 to 10%. For most motors, as long as the actual value is is within the 10% mark of the rated value, you''re in good shape.
