Today we see a tube amplifier from our customer, its configuration is really amazing.
There are some of products, which he use in this products. what about you? welcome to send to us your inquiry for the capacitors.
We can provide you excellent service, professional support.

JFGD axial flat MKP film capacitor: 1.5uF 630V
105’C Radial electrolytic capacitors 470UF 63V
105’C Snap-in electrolytic capacitors, 400V
JFL polypropylene film capacitors 0.22UF 630V 

jb capacitors company have a successful exhibition at Moscow CHIPEXPO last week. 
We receive many visits at the exhibition, customers are very interested in our samples. Catalogues and our special small gifts. 
We are very glad to meet our customers face to face. Wish we have more fruitful cooperation in future.
jb capacitors company will keep giving the fullest support for all our customers.

Our audio film capacitors are middle-high level, which loved by high-end audio makers.
They can bring out unbeatable sound performance, also awesome audio experience.

Many manufacturers of loudspeaker and amplifier bought audio film capacitors from us.
We have pretty high reputation of in Europe, there are many distributors of ours.

You will have more confidence after seeing our test reviews from our customers all over the world!
Welcome to send us your request and have samples tested!

November is coming means winter is also coming. Halloween is not far, do you have any plan to scare the children who will come to Trick-or-treat?
In Asia, not every kid plays trick-or-treat. But they can enjoy the decoration in school. Filled with pumpkin and evil witches, looks really creepy. 

Have fun and hope you will have an impressive Halloween. 

Do you hear about RC unit Capacitor? A kind of components which installed by a capacitor and a resistor as a unit.

So why do need to make such type of component? It’s quite common for us to see the resistor and capacitor is used in one circuit,
RC circuits are really cool because instead of a steady flow of current, an RC circuit is one in which the current varies over time.
If you ride your bike to work or school you know that you'll be safer when you wear a helmet with a flashing light on it. 
But what you may not know is that the light flashes because of an RC circuit! 
The duration of the flash is determined by the resistance and the capacitance in that circuit. 
For example, a small capacitance would produce a quicker flash, whereas a larger capacitance would produce a slower flash.

Chip EXPO 2017

Booth No.: B17

Date: Oct 31 - Nov 2nd, 2017

Address:"Expocentre" Moscow Russia

How time files, China is going to celebrate the traditional Mid Autumn Festival in lunar month August 15th.
To all over the world, the moon shines brighter and rounder. 
At that night, many Chinese families will gather together to eat mooncakes while appreciate the bright moon.
Herewith an interesting story for you.

Sincerely,  jb Capacitors Compmay wish you a wonderful and happy Mid-Autumn Festival.  Thank you.

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.
