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.

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.

2, The Can or Case, witch is made of aluminum material.

3, The Sleeve. usually insulating sleeve is made by PVC or PET material and with different colors. The most common color is black.

4, The Terminal. For snap in type, the terminal usually are two pins. But still with different lead out portion types, like wire, chips, screws. 

5, The Sealing Materail . Rubber stopper (EPDM rubber, butyl rubber), lug cover (needle cover, U-shaped lug cover), screw the cover (cover phenolic resin, polyphenylene sulfide resin Cover)

jb Aluminium-Elektrolytkondensatoren

Wie jeder andere Kondensator auch, besteht der Aluminium-Elektrolytkondensator aus zwei Belägen (Kondensatorplatten) und einem dazwischenliegenden Dielektrikum. 

Der wesentliche Unterschied ist, dass nur ein Belag aus Metall, einer Aluminiumfolie, besteht. Der andere Belag ist der Elektrolyt, eine elektrisch leitende Flüssigkeit (Säure), die in der Regel mit einem saugfähigen Material (z. B. Papier) getränkt ist. Das Dielektrikum zwischen den Belägen ist eine dünne Oxidschicht, die sich auf der Oberfläche der Aluminiumfolie (Al2O3) befindet. Sie wird durch Formierung hergestellt. Der Vorteil der Oxidschicht ist ihre hohe Spannungsfestigkeit. Auch bei einer sehr dünnen Schicht.
Zur Kontaktierung der elektrolytischen Schicht dient eine weitere Aluminiumfolie, die fälschlicherweise häufig als zweiter Belag verstanden wird.

Aluminium-Elektrolytkondensatoren sind Wickelkondensatoren, die es in Becherform mit radialen und axialen Anschlüssen gibt. Außerdem gibt es noch SMD-Elektrolytkondensatoren in Chip-Bauform.

Anwendung findet der Aluminium-Elektrolytkondensator als Ladekondensator im Gleichstromkreis z. B. in Gleichrichterschaltungen und zur Entkopplung elektronischer Baugruppen.
Die Funktion eines Elkos kann man am besten mit einem Widerstandsmessgerät überprüfen. Bei einem funktionsfähigen Elko steigt der Widerstandswert am Messgerät langsam bis unendlich an.
