Buddha's Birthday, the birthday of the Prince Siddhartha Gautama traditionally celebrated in East Asia on the eighth day of the fourth month in the Chinese Lunar Calendar,
The actual day is called Buddha Poomima, also traditionally known as Vaishakh Poomima.
The day marks not only the birth of Shaky amuni Gautam Buddha, but also the day of Enlightenment, and Mahaparinirvana.
But as a gentle effect of West, the event of Birth is given paramount importance.
The event is celebrated by gentle and serene fervor, keeping in mind the very nature of Buddhism.
People, especially women, go to common Viharas to observe a rather longer-than-usxial, full-length Buddhist sutra, as something like a service.
jb Capacitors wish you have a nice Buddha’s Birthday Festival. Contact us: info@jbcapacitors.com if you need any support on Capacitors.

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.
Btw, do not forget to send us the inquiry.
We have special sales for many items. Just feel free to get the most favorable price!

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.

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.
