Working Principle

The working principle of the MAL211631339E3 aluminum electrolytic capacitor is based on Faraday’s law of electrolysis. This law states that when a current passes through an electrolyte, a reaction occurs at the electrodes, producing a charge. In the case of the MAL211631339E3, this reaction causes electrolysis, where the electrolyte undergoes a chemical reaction and a buildup of charge on the electrodes. This buildup of charge creates an electric field that is stored as an electrostatic potential energy within the capacitor.

The electrochemical reaction that occurs in an aluminum electrolytic capacitor is also critical to its operation. In this type of capacitor, two aluminum foils act as the electrodes and are separated by a thin layer of aluminum oxide. The electrolyte, which contains anionic compounds, is typically present between the aluminum foils. When a current is applied to the capacitor, the electrolyte undergoes a reaction and oxidizes the foils, forming a layer of aluminum oxide that has dielectric properties. This layer of oxide acts as the dielectric material, and its thickness is determined by the applied voltage. The electric field created by the buildup of charge causes a displacement of the anions in the electrolyte, resulting in an electric charge across the capacitor. The total capacitance of the MAL211631339E3 is determined by the thickness of this oxide layer.

Conclusion

The MAL211631339E3 aluminum electrolytic capacitor is a popular choice for a wide variety of applications due to its small size, high capacitance, and superior temperature and volumetric efficiency. Its operation is based on Faraday’s law of electrolysis and the electrochemical reaction between the aluminum foils and the electrolyte. Its maximum operating voltage is 450 Volts, its dissipation factor is 0.04, and its maximum ambient temperature range is 85 degrees Celsius. This capacitor is ideal for power supplies, inverters, switching regulators, DC-DC converters, decoupling applications, and other high-frequency applications.
