jb E-cap Receive Good Feedback from Customer

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.

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.

jb Class X2 MKP Film Capacitors For Capacitive Divider Typical Circuit

After years of study, jb finally successfully developed a new series of capacitors for capacitive divider. 
X2 capacitors are used not only for EMI suppression, after upgraded, they are also suitable for voltage dividers in capacitive power supplies – for example, those of smart energy meters.

This kind of capacitor is specifically designed for applications in serial with the 100~240Vac MAIN.
Such as a small power LED driver module, small household electrical appliances control panel (electric kettle, electric cooker, coffee machine, hair straightener etc.), 
thermostat, replace the transformer. Also widely used in LC resonant, high frequency high current situation.
