Except for a few surface-mount technology (SMT) aluminum electrolytic capacitor types with solid electrolyte systems, an aluminum electrolytic capacitor consists of a wound capacitor element, impregnated with liquid electrolyte, connected to terminals and sealed in a can.
In non-polar aluminum electrolytic capacitors and motor-start aluminum electrolyte capacitors a second anode foil substitutes for the cathode foil to achieve a non-polar capacitor in a single case. These figures show typical constructions of the non-surface-mount aluminum electrolytic capacitors.
Aluminum electrolytic capacitor construction delivers colossal capacitance because etching the foils can increase surface area more than 100 times and the aluminum-oxide dielectric is less than a micrometer thick. Thus the resulting capacitor has very large plate area and the plates are intensely close together.
Other types of aluminum electrolytic capacitors not cov-ered include the obsolete wet types without separator mem-branes, “hybrid” aluminum electrolytic capacitors containing both polymer and liquid electrolyte components and sol-id-polymer electrolytic capacitors.
The best method is by cold-welding of the tabs to the foils with tab locations microprocessor controlled during winding so that the capacitor element’s inductance can be less than 2 nH. The older method of attachment is by staking, a process of punching the tab through the foil and folding down the punched metal.
Aluminum electrolytic capacitors contain materials which can catch fire and support combustion when contacted by flames. Flammable parts include plastic parts, insulating sleeves, paper, and the electrolytes. Most capacitors will pass the needle-flame test requirements of UL 94V-O and not support combustion to the requirements of Category B or C.
