jb Terminals from Customer for JFX, JSX and Snap-in Aluminum Electrolytic Capacitors in Audio Applications

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.

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.
