You know that we have JFX and JSX for using in audio equipment. We also have another capacitors that is good in audio equipment field.

JNE is our strong product and popular in making audio application.

It can also present awesome sound performance to you. If you have any interest in our JNE series, you can place a trial order or ask some samples from us.

We may try best to meet your demand. Welcome to send me your exact inquiry or ask for FREE SAMPLES! info@jbcapacitors.com

Our jb Capacitors Company produce E-cap since 1980, with high quality, fast delivery time & very good prices.

Many big distributor and manufacutres buy E-cap from us for long time, below is one of our customer’s good feedback. We would like to share to all of you :

We are buying your E-caps since 2009, and so far we have good track record with them.

We are in the high quality custom power supply business. Most of our products are designed for 30 years operating life. As you noticed, our purchasing quantities steadily increased for your E-capacitors, and we plan to do so.

However, the past taught us to be tedious to collect reliability record on many critical items, mainly E-capacitors.

As said, in the coming year, we will increase our purchases from JP Capacitor, since we are very happy with your service, support and response times.

Please check our products link: http://www.jbcapacitors.com/Aluminum-Electrolytic-Capacitors/ and send us more E-cap inquiries. We’re always ready to give full support for you.

Our JFX & JSX series are spoke highly by our customers, in their test our quality is very reliable and sound result is very good. 

We did many tests to the capacitors supplied by your company, in order to check both sound result and reliability.
Both capacitors JFX Premium and JSX Superior have shown good reliability characteristics and passed our tests well. 
When we did sound tests, the capacitors of the JFX Premium serie was very good, and can compete with the famous capacitors made by the company MUNDORF. 

The electrolytic capacitors have shown a good reliability as well, and quite good sound result. From our tests, we found that the JNK serie was superior to the JNG series.

From Silvia - Laboratorio Audio snc

We are looking forward to receive your request of capacitors for quote.
We can provide very flexible MOQ for customer to test the market at the beginning. 
We can provide reliable quality and competitive price.
We can provide free samples to show our high quality. 

We not only produce these audio capacitors, but also provide many other kinds of capacitors with very good prices and short delivery, reliable quality and good customer service.

Send us your request please, you will receive very satisfied offer from us.

Today we introduce the Main Methods of Testing E-cap Lifetime. 

Usually we have two methods for testing lifetime, please find more detail information as below:

1. Normal testing: (Periodic sampling is conducted every four months)
The environment temperature test: 20 ℃~25 ℃     
Relative humidity: 45%-75%    
Relative air pressure: 86kpa-106 kpa 
Inspection items: High temperature 105 ℃ storage 3000 Hours      
High temperature life test the durability:  3000 Hours 

For above test, we have exact equipment for testing, after testing, the real test data can prove the product of real lifetime. 

2. Destructive testing: (do the regular sampling inspection every 2 months)
Put the capacitors in the oven, the temperature raise 10 degrees (for example: if the capacitors' oringinal temperature is 105 ℃, it needs rise to 115 ℃). 
let current go through (should be the capacitor's current),  then the capacitors' lifetime will decay half. (it means, 3000 Hours becomes 1500 hours), after testing 63 days, will take out capacitors and see if it can still work or not.

Elektrolitik kondansatorlerde dielektrik madde olarak asit borik eriyigi ya da borakslı elektrolitler bulunur. İletken levhalar ise aluminyum ya da tantalyum plakalardır. Elektrolitik kondansatorler, kutuplu ya da kutupsuz olarak uretilirler. Kutuplu olan kondansatorler DC devrelere baglanırken artı ve eksi uclara dikkat edilmelidir. Yanlıs yapılan baglantılarda anotta bulunan oksit tabakası metal yuzeyi kısa devre edip, yuksek ısı olusumuna ve kondansatorun patlamasına yol acabilir.

Elektrolitik kondansatorler sıvılı tip ve kuru tip olarak ikiye ayrılır. Sıvılı tip elektrolitik kondansatorler sadece DC devrelerde kullanılabilen, pozitif levha olarak aluminyum barındıran kondansatorlerdir. 
Bu tip kondansatorlere DC akım uygulandıgında, pozitif levha üzerinde yalıtkan bir oksit tabakası oluşarak dielektrik gibi davranır. Olusan bu tabaka cok ince oldugundan kondansatorun kapasitesi yuksek olur. Kuru tip elektrolitik kondansatorlerde ise elektrolitik sıvı yerine boraks eriyigi emdirilmis kagıt ya da bez kullanılır.

Elektrolitik kondansatorlerde bulunan elektrolitik sıvısı asırı sıcak nedeniyle zamanla kurumaya basladıgından, kondansatorun kapasite degeri dusebilir ve bu durum hassas devrelerin calısma sisteminde arızalara neden olabilir.

Basic construction:
1, Two pieces of foils interleaved with an absorbent paper build up the key element of an Aluminium Electrolytic Capacitor, and all these materials should be wound tightly into a cylinder shape
2, The positive foil, or the anode foil are all made from pure aluminium foil. The aluminium oxide dielectric has been formed electrolytically on the surface.. 
3, The foil has been etched to make the effective surface area more larger, and the area of the anode is usually 30–100 times larger than the plan area of the foil.

Figure: How dielectric structure works in an Aluminium Electrolytic Capacitor ?
4, The other plate is a combination of high-absorption paper impregnated with an electrolyte, in contact with a cathode foil. 
5, The electrolyte is there to make good contact with the anode, by permeating its etched structure, and also to repair any flaws in the oxide layer when the capacitor is polarised. 
6, The function of the aluminium cathode foil is to reduce the series resistance of the capacitor by making contact with the paper over a wide area.
