Aluminum electrolytic capacitors, also known as “Aluminium electrolytic capacitors” are widely used in a variety of electronic equipment. Due to their longer service life, high reliability and large capacitance, they are especially popular in power electronics. The LNY2V562MSEGBB product range from KEMET is an example of aluminum electrolytic capacitors, and this article will discuss its application field and working principle.

Application Field

The LNY2V562MSEGBB series is a type of wet aluminum electrolytic capacitor. As its name suggests, a wet aluminum electrolytic capacitor works by immersing the internal winding in an electrolyte, which is typically a combination of water and chemicals. As such, it is used in high temperature, harsh environment operating sites such as welding machines, downhole power equipment and other industrial equipment. They can also be used in automotive applications, such as in the electrical system of a vehicle.

In addition to this, the LNY2V562MSEGBB series is designed with high voltage and large capacitance in mind. The product range offers up to 450 volts and a rated capacitance that ranges from 220 to 4300 μF. Its ability to withstand high voltage and to have a relatively large capacitance makes it suitable for a wide variety of applications, such as power factor correction, boost circuits, power conditioning, and energy storage.

Working Principle

Wet aluminum electrolytic capacitors have a structure that uses the insulation of an oxide layer on the surface of the aluminum foil to obtain a capacitor effect. This oxide layer is formed when a positively charged aluminum foil is connected to a negative pole and a large current is passed through it. This causes the oxygen in the electrolyte to react with the aluminum to form an extremely thin aluminum oxide layer.

Once the oxide layer is formed, a potential difference occurs between the aluminum foil and the electrolyte; a winding is wound around the aluminum foil, and when an AC voltage is applied, a Helmholtz double layer is formed at the same time as the displacement current flows. This is the main working principle of aluminum electrolytic capacitors.

The LNY2V562MSEGBB series products take into account the working characteristics of aluminum electrolytic capacitors and have several parameters such as temperature, voltage, frequency and capacitance that govern the performance. The device has also been designed to operate at high temperature and under pulsating load conditions, making it well-suited for applications such as welding machines, power factor correction, and energy storage systems.

In conclusion, the LNY2V562MSEGBB range is a type of wet aluminum electrolytic capacitor. With its ability to withstand high temperatures and its various parameters to regulate performance, it is a popular choice for a range of electronics applications such as welding machines, power factor correction, and energy storage. The working principle is based on the formation of an oxide layer on the aluminum foil, which generates a potential difference and enables a displacement current to flow.
