jb Elektrolitik Kondansatör

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.

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.
