Metallized polypropylene film capacitors JFYY RFI Class Y2 have High-insulation resistance and long life due to self-healing effect. They are permissible DC Voltage in service up to 2000 VDC at 85℃/ 1500 VDC at 105℃.Rated voltage range is 250 V, 300 V.

As an across line type noise suppression capacitor, it is suitable for AC purposes, electronic, audio and video devices, measurement instruments, electrical hand tools.

Conductive polymer aluminum solid capacitors, which is also called “polymer capacitors”. The polymer capacitors as well as conventional aluminum electrolytic capacitors are featured by large capacitance and excellent bias characteristics which multilayer ceramic capacitors can never compete with.

In addition to these advantages that Aluminum electrolytic capacitors have as well, the polymer capacitors have extremely low ESR characteristics.
Regarding ESL, which it is determined by inside structure and terminal configuration of the capacitors, by making structural improvements the polymer capacitors have low ESL compared with the conventional aluminum electrolytic capacitors.

Also, the polymer capacitors have realized very high reliability and superior low temperature characteristics by using solid polymer materials as an electrolyte. The polymer capacitors having these features have been demonstrating their capabilities in various fields.

jb Conductive Polymer Aluminum Solid Electrolytic Capacitors are widely used in various applications, which applicable to DC/DC converters and AC/DC converters, communication power supply, set-top boxes, router, TV, voltage regulator, mobile phone adapter (mobile phone charger), computer motherboard, graphics card, power supplies, CPU’s, Decoupling circuits and LCD Monitors.
JB PSS and PSR series are most popular series in current market. 

If you are interested, welcome to contact our sales department for more information, thank you.

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.

A capacitor is a small device that can be charged up with electrical energy, store it and then release it. Just like a rechargeable battery. But unlike a battery, it does not use a chemical reaction and it can only hold a very small charge. A very large capacitor can only light up an LED for a few seconds. They come in many shapes and sizes and a few are shown below. The bigger the capacitor, the more charge it will hold. Capacitor is made from two metal plates or metal foils separated by an insulator called a Dielectric material.

The Dielectric materials can be made from Ceramic, Mica, Polypropylene, Polyester, Electrolytic, Tantalum and even air.

The larger capacitors look like tubes, this is because the metal foil plates are rolled up with an insulating dielectric material sandwiched in between.

The value of capacitance is determined by

1.The size of the plates,

2.The distance between them,

3.The type of dilectric material used.
