Dingfeng Capacitor---How long should my Run Capacitor last?

Q:  How long should my Run Capacitor last?

A:  The mid point for a good quality aftermarket run cap (one that didn't come with your motor) would be 30,00-60,00 running hours. Factory installed motor run caps sometimes have a designed lifespan of much less that this. In highly competitive industries where every part can have a significant impact on cost, or where a motor's intended use would likely be intermittent and infrequent, a lower grade of capacitor may be selected with a design life of as little as 1000 hours. Additionally, all of the factors from the section above (causes of failure) may dramatically modify the reasonable expected life of a capacitor.
