Aluminum electrolytic capacitors are widely used in various electric appliances, digital and communication products as important components due to their advantages, such as large capacitance, high voltage, small size, low cost and long life.MAL202115222E3 is a kind of aluminum electrolytic capacitor with its own unique advantages, and its application field and working principle will be introduced in this paper.

Application Field of MAL202115222E3

MAL202115222E3 can be widely used in various fields due to its own advantages. In wireless communication and system processing field, its excellent frequency characteristic makes it can be used in various high-frequency communication equipment, such as mobile phones and base stations. In addition, frequency divider and filter can be applied in various frequency control and signal processing occasions due to its low temperature coefficient and low equivalent serial resistance.

In addition, the excellent surge voltage and ripple current characteristics of the MAL202115222E3 make it suitable for use in the switching power supply. The use of such capacitors can significantly reduce the output voltage ripple of power supplies and reduce power supply noise, making them an important part of switching power supplies.

In the equipment for aerospace and military electronic devices, MAL202115222E3 is also very popular due to its large improvement in high temperature, low temperature and vibration resistance. By using high-quality aluminum electrolytic capacitors, it can guarantee the stability and safety of the system under severe conditions.

Working Principle of MAL202115222E3

MAL202115222E3 is an aluminum electrolytic capacitor with a positive polar plate made of an aluminum foil that has been oxidized and etched. A rectangular capacitor element is formed on the inner and outer surfaces of the aluminum foil, and then wound with several layers, and finally sealed and sealed with a special dielectric liquid, forming an aluminum electrolytic capacitor.

When the MAL202115222E3 is in operation, the current flowing through it is divided into two paths. The first path is through the capacitor element of the aluminum foil. Because the capacitor element is covered with dielectric liquid and the space is very small, it is almost a dead place and the current flowing through it is very small, so it almost doesn’t take part in the capacitance operation. The second path is the polar electrolyte liquid. Since the dielectric liquid has a relatively large capacitance, most of the current flows through it. The electric field generated by the polar electrolyte liquid makes the aluminum foil begin to form a capacitor element.

So the working principle of MAL202115222E3 is very simple, it holds the characteristics of a large capacitor, its equivalent series resistance and equivalent series inductance are low, the frequency response is wide, and its voltage resistance is also excellent. With these advantages, the MAL202115222E3 is widely used in various application fields.
