A motor run capacitor is used to continuously adjust current or phase shift to a motor’s windings in an effort to optimise the motors torque and efficiency performance. 
All run capacitors are designed for continuous duty, and as a result, have a much lower failure rate than start capacitors.

Main Feature:
Motor run capacitors utilize low-loss Metallized polypropylene Zinc aluminum film for dielectric. 
The motor run capacitors are encapsulated with resin and housed in a self-extinguishing plastic case which allows for superior reliability and a high mechanical shock and vibration strength. 

The motor run capacitors is ideal for start and run applications in single-phase asynchronous motors and general A.C. applications at industrial frequencies. 

The motor run capacitor is small in bulk, has long life-span and good self-healing characteristic. 

The motor run capacitor is widely used as the start up and running capacitor that is special for micro water pump, cleaning machine, washing machine, and single-phase water pump motor.

We received the capacitors from you and all cartons are ok, thank you.
First of all I want to thank you for the samples and gifts that you sent, I appreciate your kindness.
I checked all models of motor capacitors to see if they have the right capacity value.
The models between 10u and 80u have the right capacity, many models have 2-3% bigger capacity than rated, this is very good.
For example, 30uF has in fact 31uF.

The problem is with the models 100uF and 120uF.
100uF has in fact around 91uF; 120uF has in fact around 101uF

I would like to know why these models have such a low capacity.
I didn't expect to have such differences, I consider jb Capacitors to be a big factory with good quality.
It is important to know, I hope that next time we can find a solution to make these models with the rated capacity.

jb Capacitors Response: Thursday, July 13, 2015 12:45 PM
Before goods leaving our factory, we did all necessary electrical performance test & inspect, totally 3 times.
we made a JFS-15 100uF capacitor test with HF2618 instrument, a professional instrument for capacitance test.

Customer Sent: Thursday, July 16, 2015 5:48 PM
I am very glad to tell you that we tested the motor capacitors 100u and 120u with an oscilloscope that can also measure capacitance and the result is positive, the capacitors have indeed around 100u and 120u.
There is no problem to measure capacitors less than 100u with this general multimeter 9205, but for bigger capacitors we need indeed to use a professional instrument.
So I am glad that there is no problem with these capacitors from you. We are planning our next order very soon.http://www.jbcapacitors.com/
