MAL205753151E3

Aluminum Electrolytic Capacitors are widely used in various electrical and electronic devices as passive components, such as signal coupling and filtering. Among them, MAL205753151E3, a kind of radial aluminum electrolytic capacitor, features a rated capacitance of 8.3mF, rated voltage of 10V, and a floating inner sleeve as a connection terminal. In this article, the application of the product and its working principle will be discussed.

Application Field

MAL205753151E3 has a wide range of applications. For instance, it is often used to prevent interference and filter signals. Thus, it can be applied in radio or television set equipment, communication equipment, remote-control apparatus, digital products and AC/DC adapters, in order to reduce noise and effectively operate the communication or transmission process.

In addition, due to its function of energy storage, the product can also be used as a start-up energy support in some electronic machinery, such as motor drives, gate drivers, servo systems, and automatic motors.

Furthermore, it can also be implemented in precision instruments, such as thermostats, humidity monitors, and multimeters, in order to buffer the voltage within certain range and provide more reliable performance.

Working Principle

The working principle of MAL205753151E3 can be explained through a constructional perspective. The product is composed of a roll of aluminum foil strip with etched grooves, which acts as one electrode, and a separator paper, which is soaked with an electrolytic solution, that acts as the other electrode. The roll is then tightly rolled inside the cathode can with low moisture content material, which acts as insulating material.

When both ends of a capacitive element are connected to a DC power supply, an electrical separation process takes place, resulting in the formation of an electric field. The electric field transports anions from the electrolytic solution to metal plate, while cations move in an opposite direction. The anions will electrolyse on the plate and form a solid-state conductive film.

With the formation of the film, an electrical capacitor would be generated, with one plate connecting to the DC power, and the other plate connecting to the electrolyte. Also, as the charged electric fields expand, the distance between the plates increases, reducing the capacitance output.

Conclusion

MAL205753151E3, as an aluminum electrolytic capacitor, has a wide range of applications, such as signal coupling and filtering, energy storage, and precision instrument buffering. Its working principle can be explained through a constructional perspective, based on the electric field generated by a DC power.
