Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are power capacitors used in various electric and electronic circuits. They are widely used in the fields of communication, radio broadcasting, power, measurement, aerospace, etc., and are active components in circuits. The MAL203871479E3 is one of the most commonly used aluminum electrolytic capacitors.

Application Field of MAL203871479E3

The MAL203871479E3 is a common type of aluminum electrolytic capacitor used in many power supply circuits. It is suitable for all kinds of electronic and electrical circuits. Due to its stable performance, high safety performance and reliable operation, it has become the choice of many users. It is widely used in power management systems, industrial control, automatic control, frequency conversion control, railway signaling systems, power inverters, traditional and renewable energies, motor control systems, UPS systems, medical equipment, household appliances, etc.

Working Principle of MAL203871479E3

The MAL203871479E3 aluminum electrolytic capacitor is composed of three layers of aluminum, paper, and electrolyte. The principle of aluminum electrolytic capacitor is similar to that of general capacitor. It is composed of two metal sheets with a certain area. An insulating paper is placed in between, and the inner and outer surfaces of the capacitor are coated with electrolyte. When there is a voltage difference between the two terminals, the positive and negative charges on the two plates are counteracted by the electric field, and the electric energy is stored.

The MAL203871479E3 aluminum electrolytic capacitor is different from the general capacitor in its formation process. First, a thin film of oxide film is formed on the surface of aluminum foil. Then, the paper washer and electrolyte were stacked on the two sides of the aluminum foil. In this way, excellent performance of the aluminum electrolytic capacitor can be achieved. The oxide film on the surface of aluminum foil is an important component, because it can increase its capacitance. And due to its large size, the oxide film is relatively stable, so the performance of aluminum electrolytic capacitor is also stable.

The working principle of MAL203871479E3 aluminum electrolytic capacitor is mainly due to the capacitance of the oxide film on its surface. When a high voltage is applied to its two terminals, electrons rush into the layers of the aluminum foil, forming an electric field, thus realizing the energy storage effect. In the actual application process, the greater the voltage, the greater the amount of charge stored in the capacitor, but at the same time, when a certain voltage is exceeded, the oxide film on the surface of the aluminum foil will burst, causing the capacitor to break down. Therefore, it is very important to choose the appropriate voltage for aluminum electrolytic capacitors according to the actual needs.

Conclusion

The MAL203871479E3 is an aluminum electrolytic capacitor with a wide range of applications, including power managements, industrial control, automatic control, frequency conversion control, railway signalling systems, power inverters, traditional and renewable energies, motor control systems, UPS systems, medical equipment, and household appliances. It is composed of three layers of aluminum, paper, and electrolyte, and its working principle is mainly based on the capacitance of the oxide film on its surface. The oxide film is the key to its large capacitance, and the size of the oxide film determines the performance of the aluminum electrolytic capacitor.
