jb Tell You The Basic Structure of An Aluminum Electrolytic Capacitor

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)
