Aluminum electrolytic capacitors are widely used in electronic circuits due to their high capacitance and low price. MAL211816152E3 is one of the most popular aluminum electrolytic capacitors available today. In this article, we will discuss the application fields and working principle of MAL211816152E3.

MAL211816152E3 is a radial aluminum electrolytic capacitor, and its maximum capacitance value is 1.5F. Its rated voltage is 6.3V, and its maximum surge voltage is 10V. It has a temperature range of -55°C to +105°C, and a life of 3000 hours. The main applications of MAL211816152E3 are for filtering, combining, blocking, and decoupling signals in general purpose electronic circuits.

At the core of MAL211816152E3 is a sealed dielectric made of aluminum oxide. This dielectric is formed by anodizing aluminum foil in an electrolyte solution. During the anodization process, the aluminum molecules are broken down into the oxide layer. This oxide layer acts as an insulator between two metal plates, forming a capacitor.

In order to provide the required capacitance, two aluminum foils are stacked together in an alternating fashion and then sealed in a hermetically sealed can. The can is then filled with an electrolyte solution. The electrolyte solution performs two important functions. First, it acts as a medium for conducting the electrical current flow between the two metal plates. Secondly, it acts as an additional insulator, further increasing the capacitance.

The working principle of MAL211816152E3 is based on the dielectric properties of the aluminum oxide. As a voltage is applied across the two metal plates, electrons are attracted to the positive plate and repulsed from the negative plate. This creates an electric field between the metal plates, which is capable of storing energy. As the voltage across the plates increases, the electric field also increases, resulting in a higher capacitance.

In summary, MAL211816152E3 is an aluminum electrolytic capacitor with a maximum capacitance of 1.5F. Its primary applications are for filtering, combining, blocking, and decoupling signals in general purpose electronic circuits. Its working principle is based on the dielectric properties of the aluminum oxide. By controlling the voltage across the two metal plates, different levels of capacitance can be achieved.
