Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that uses an aluminum foil as its anode and a paper or ceramic dielectric as its medium. Its construction is similar to that of an electrolytic cell, and the outer terminals can be seen as the two electrodes that keep the plates separated. These capacitors offer a high capacitance for a given volume and are one of the most common types of capacitors used. The operating voltage of these capacitors is generally low and the amount of current it can handle is limited.

Application Field and Working Principle of the 420KXF120MEFC30X20 Aluminum Electrolytic Capacitor

The 420KXF120MEFC30X20 aluminum electrolytic capacitor is suitable for applications where low-loss, high ripple current capacity and a high-capacitance for a given size are desired. Its main uses are in audio, switching power supplies, personal computers, automotive electronics, power line filtering, and industrial control systems. The working principle of the 420KXF120MEFC30X20 is relatively simple. It operates using the basic principles behind a capacitance and a leakage current. When a voltage is applied across its plates, electrons travel through the dielectric medium and store electric potential energy. The capacitance of the capacitor is determined by the amount of electric potential energy stored in the capacitor. The leakage current is relatively low because of the higher resistance value of the dielectric medium, thus restricting the amount of charge that can enter or exit the plates.
