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 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 Structure of Aluminium Electrolytic Capacitors

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.

We welcome you to order our jb Aluminium Electrolytic Capacitors and anatomy it, if you want to have a more clear understanding of them. Do it yourself will be more fun and meaningful.

jb What's Photoflash Capacitors

A photoflash capacitor is an electrolytic capacitor used in flash cameras, professional flashes, and also in solid-state laser power supplies. Their usual purpose is to briefly power a high-voltage flash tube, used to illuminate a photographic subject or optically pump a laser rod. As flash tubes require very high current for a very short time to operate, photoflash capacitors are designed to supply high discharge current pulses without excessive internal heating.

Photoflash Aluminum Electrolytic Capacitors are very special capacitors and need very high quality and professional  technology. I have friends told me that jb Capacitors Company produce very good quality photoflash electrolytic capacitors. JSU Series--Photo-Flash-Lug-Aluminum-Electrolytic-Capacitors. Here is the datasheet link:http://www.jbcapacitors.com/Aluminum-Electrolytic-Capacitors/JSU-Photo-Flash-Lug-Aluminum-Electrolytic-Capacitor.html

jb Snap-in Aluminum Electrolytic Capacitors used in Motor

jb capacitors company is very strong on Aluminum electrolytic capacitors, including snap-in, screw type and lug type.

Snap-in Aluminum Electrolytic Capacitors is widely used on power supply. If the end product is industrial motor, some customer may requires to add a mica sheet of plastic layer or other non-flammable material between the Aluminum electrolytic body and PCB. As we know, the motor has vibrations, and it keeps running 24 hours, so that the capacitor will be very hot. The piece of plastic layer is used as insulation to prevent the capacitor from shorting itself.
