Keywords: JFW X2, jb MPX/MKP X2

jb MPX/MKP Class X2-MPX Safety Standard Capacitor is mainly used for power input L/N dredging for EMI suppression, and the input port used in parallel.

The most common use of the JFW AC-Capacitors Suppression Capacitors Class X2 AC 310V is anti-electromagnetic interference, suitable for high frequency,DC, AC, coupled, cross-pulse circuit, for example white goods, home appliance etc.

In addition, jb JFW Safety Film Capacitors can withstand the impact of overpressure, and it also has excellent capabilities of flame resistance and moisture resistance.

Compare with other capacitors, JFW Radial Class X2 310VAC Capacitor is very stable, it is less affected by the voltage.

JFW monthly output is about 20KKpcs per month now, and delivery time is about 4~5 weeks.

The capacitance of JCV series aluminum electrolytic capacitors is defined by the surface of the aluminum anode foil. This surface is maximized by special etching processes, giving these capacitors the highest volumetric capacitance of all capacitor technologies and thus an attractive cost per capacitance ratio. jb capacitors chip types aluminum electrolytic capacitors feature outstanding ripple current capabilities, very long-term reliability, 105℃ Long Life, Low Impedance, and Lead Free Reflow Soldering.

Aluminum electrolytic capacitors (electrolyte) are widely used in power supply applications requiring high capacitance in energy-dense, small-volume packages having very low equivalent series resistance (ESR). For JCV chip type Aluminum electrolytic capacitors, are found in many applications such as power supplies and computer motherboards. These capacitors are used when a large capacitance is required and leakage current is not an important factor.

jb Capacitors manufactures X2 Metallized Polypropylene Film Capacitor, which also named Interference Suppression Capacitors or X2 Safety Capacitors. It is the strongest series in our plastic film capacitors.

jb JFZ-X2 Safety Capacitor, has VDE, ENEC, UL and cUL approvals. 

Application: 
As an across-the-line type noise suppression capacitor, and suitable.
Grid power supply of electronic instruments and electronic equipment, switch, contacts produces a 
spark discharge sites.
Electric tools, lighting, hair dryers, water heaters and other household electrical appliances.

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.
