Environmental and Application Factors Beyond the electrical specifications, the physical environment where the motor operates can influence capacitor selection. High ambient temperatures can degrade the dielectric material inside capacitors, leading to a loss of capacitance over time.

Voltage Rating The capacitor's voltage must be equal to or greater than the motor's voltage rating. Operating a motor with a capacitor that has too high or too low a µF rating can cause the windings to overheat.
These capacitors have lower capacitance values, generally ranging from 4 to 20 µF, but they are built to withstand continuous operation at higher voltages, often 370V or 440V AC. An incorrect value, whether too high or too low, can lead to reduced efficiency, excessive heat, and ultimately, premature failure of the motor windings.

Selecting the correct motor capacitor size is one of the most critical decisions for ensuring the reliable operation of single-phase electric motors. Conversely, a capacitor that is too large can overheat the windings due to excessive current, significantly reducing the motor's lifespan.
