Capacitor Construction and Working Principle

The basic construction of the 50USC4700MEFCSN30X25 aluminum electrolytic capacitor contains two pieces of aluminum foil with an oxide layer on their surfaces to form a dielectric barrier. The plates are wound together with a separator and soaked in an electrolyte solution. On one plate is a layer of insulator that is protected by a sleeve. The solution between the plates is the electrolyte and forms a small amount of capacitance. The outside of the capacitor is then sealed, usually in an epoxy case and the outside terminals are connected to the plates.

The basic working principle of the 50USC4700MEFCSN30X25 aluminum electrolytic capacitor is that of a conventional capacitor. When a potential is applied to the capacitor, the electric field across the dielectric layer creates a charge on the plates. The amount of charge depends on the size of the plates and the tension of the electric field. This charge creates a potential difference across the plates that creates a current through the electrolyte. This current gives a momentary gain in the amount of charge stored in the capacitor.
