BUILDING AN ELECTROLYTIC CAPACITOR

PublishTime：2021-03-15

A capacitor is an electrical component that stores a quantity of electrical charge defined with a linear relationship as:
Usually values are indicated in a smaller unit called micro Farad [μF] that is one million times smaller. An aluminium electrolytic capacitor is composed of one anode of aluminium foil having a dielectric oxidation on its surface, with semiconductor characteristics to prevent the current flow in one direction, and another aluminium foil cathode. There is also an electrolyte impregnated paper layer positioned between the anode and the cathode in order to avoid short circuits. Both the aluminium foils have been etched to obtain active surfaces, increasing their effective area. Aluminium tabs are then connected to the two foils to act as terminals.
When in use the impregnated section is then closed inside an suitable case and sealed with a deck. The matching of thin dielectric and a large surface area allows to create capacitors with exceptional high capacitance per volume.European (CECC) and International standards (IEC) have classified the capacitors in two categories. Electrolytic capacitors for high reliability applications (Long Life Grade): in addition of the possible over anodization (the difference between forming voltage and operating voltage) must generally satisfy high endurance requirements and a careful selection on materials is needed, such efforts are not required for capacitors standard version used for less severe reliability (General Purpose Grade).
The whole manufacturing process requested to build a Kendeil electrolytic capacitor could be reasonably split into the following phases:
● Etching / Forming
● Winding
● Impregnation
● Sealing
● Ageing
● Production Inspections
