jb Class X2 Metallized Polypropylene Film Capacitor Up to 310VAC --- JFZ

Do you know what is the best seller in jb Capacitor Company? You will say plastic film capacitors, right? Yes, you are definitely right.
But the most strong series in our plastic film capacitors is Class X2 Film Capacitor JFV.
In year 2015, we will launch a new series that is the sister series with JFV, we call it JFZ. Both of them are produced by jb Capacitor Company.

Both of them get individual UL, cUL, VDE, ENEC approval.  
Class X2 JFV UL file Number : E344970 , ENEC-VDE  file Number : 40035534 
Class X2 JFZ UL file Number : E344970,  ENEC-VDE  file Number : 40041888

But In some regards, JFZ is a upgraded level compared with JFV.
JFV Passive flammability category is Class C, JFZ Passive flammability category is Class B.
However, in order to give best support to customers, our JFZ price even can compete with JFV. 

Below is the basic information of our JFZ Class X2 Metallized Polypropylene Film Capacitor 310VAC.

From: Sergei
Dear May, 
We did tests as well with jb Capacitors from our foreigner colleagues, and we found that quality is very good, and one more thing--they Looks Nice which is also important!
So we decided to send you our order to see your proposition for full list, including items we asked you earlier, we will do this order at this time. 
Best Regards,

jb Capacitors Motor-Start-Capacitor

Start capacitors above 20 microfarads (µF) are always non-polarized Aluminum Electrolyic Capacitors with non solid electrolyte and therefore they are only applicable for the short motor starting time.

Start capacitors briefly increase motor starting torque and allow a motor to be cycled on and off rapidly. Start capacitors have ratings above 70 microfarads (µF), with four major voltage classifications: 125 V, 165V, 250 V, and 330 V. A start capacitor stays in the circuit long enough to rapidly bring the motor to 3/4 of full speed and is then taken out of the circuit, such as by a centrifugal switch that releases at that speed. The motor after that runs more efficiently with a run capacitor.

jb Tell You How to Test A Capacitor with An Ohmeter

You can use your multimeter as an ohmmeter to test the capacitor.

1) Discharge the capacitor by shortening its leads. that is - use a wire and connect the leads of the capacitor together. this will discharge it.
2) Put your multimeter in the high ranges 10k-1m
3) Connect multimeter to capacitor leads(observe the polarity if electrolytic). at soon as the leads make contact, the meter will swing near zero. it will then move slowly toward infinity. finally the meter would come to be infinite ohms because the capacitor is being charged by the battery of the multimeter.
4) If the capacitor is bad, it will go to zero ohms and remain there. this is called a shortened capacitor
5) In the case of an open capacitor there will be no ohmmeter indication.
6) Some capacitors have a low dielectric leakage. you will know this if the ohmmeter comes to rest at a point lower than infinite. test a known good capacitor of the same type to be sure.

This test works for large capacitors. Tiny capacitors can only be checked with a capacitance meter, or by using them in an AC circuit and checking for variation from calculated voltage drop.
Pls. focus on jb most strong series:  JFB--MKT (Metallized Polyester ) Film Capacitors &JFV--X2 MKP (Metallized Polypropylene) Film Capacitors.
