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.

During the Lantern Festival, people will try to solve the puzzles on the lanterns and eat yuanxiao (glutinous rice ball). 

Best wishes to all of our jb Capacitors Company partners.

jb Capacitors manufactures and markets Aluminum Electrolytic Capacitors, including Snap-in Type 
Aluminum Electrolytic Capacitors, Screw Type Aluminum Electrolytic Capacitors, Lug Type Aluminum 
Electrolytic Capacitors and Leaded Radial Aluminum Electrolytic Capacitors , also SMD Aluminum Electrolytic Capacitors.

Today we would like to share with the the basic structure of  jb Snap-in Type Aluminum Electrolytic Capacitors. 

1, The most important part is the Core , or called as element. 
Aluminum electrolytic capacitor winding core is made of aluminum foil anode, electrolytic paper, aluminum foil cathode , electrolytic paper, totally made four layers overlap;

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)
