jb Tell You the Main Methods of Testing E-Caps Lifetim

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.

jb Elektrolitik Kondansatör

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.
