Working Principle

MLP111M450EK1D aluminum electrolytic capacitors work on the principle of electrolysis. An electrolytic solution is used to form a thin film of metal oxide on an oxidized aluminum anode. Through electrolysis, a very thin oxide layer is formed on the aluminum anode of the capacitor. This oxide layer acts as a dielectric insulator, separating the anode from the cathode. This oxide layer and the electrolytic solution form an extremely thin dielectric layer with a very small value of dielectric constant. This layer is extremely thin, yet still relatively strong, and it allows electric charge to flow but restricts electric current from passing.

The electrodes of an aluminum electrolytic capacitor are usually made of solid aluminum foil as the anode and electrical grade paper as the cathode. The paper acts as the dielectric, while the aluminum oxide layer acts as an insulator. The electrical grade paper is saturated with an electrolyte solution, usually a mixture of ammonium bicarbonate and boric acid, and the electrolyte solution is then sealed with a dielectric material such as mica or polyester. This helps maintain the electrical properties of the capacitor.

In conclusion, MLP111M450EK1D aluminum electrolytic capacitors are widely used for filter, bypass, decoupling, and coupling applications in a range of industries. The capacitor is made of aluminum foil, electrical grade paper, and an electrolyte solution, and works on the principle of electrolysis. This type of capacitor has a high capacitance, low ESR, and a long lifespan.
