Working Principle

An aluminum electrolytic capacitor works by using the anode aluminum foil, cathode electrolyte, and separators. This combination of these allows the capacitor to store electric charges. The separators are made up of paper or plastic film that separates the anode and cathode.

The aluminum foil anode is exposed to the electrolyte and it is also etched, providing numerous small metal oxide surfaces and electrolyte penetrates over this surface. As an electrical potential is applied across the two electrodes, a capacitor is formed. This capacitor stores the electric charge, and the number of electrons that can be stored is determined by the size of the surface area. The electrolyte is responsible for the dielectric material in a typical aluminum electrolytic capacitor and the electrolyte must remain liquid and not freeze.

The thickness of the surface oxide layer of the aluminum foil is determined by the capacitance and it can range from 2-100 nm. The higher the capacitance, the thicker the oxide layer. The voltage rating of the capacitor is determined by the thickness of the oxide layer, which will expand and become thinner when increased amounts of electric charges are present.

Conclusion

The ELXY630ELL100MEB5D aluminum electrolytic capacitor is an ideal choice for a variety of applications due its high capacitance, high current capability, and wide temperature range. The working principle of the capacitor involves the anode aluminum foil, electrolyte, and separators, which allow the capacitor to store electric charge.
