Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that uses aluminum oxide as the dielectric material. It is composed of two aluminum foils, separated by a thin sheet of oxide that is generated and maintained in situ by anodic oxidation of the anode foil. A polarized electrolyte is absorbed by the dielectric oxide layer and forms the second electrode. This type of capacitor is compact and has a high volumetric efficiency.

LQR2G821MSECBB Application Field and Working Principle

The LQR2G821MSECBB is an aluminum electrolytic capacitor that is mainly used for voltage filtering and energy storage applications. It is rated for a rated voltage of 15VDC and has a specified capacitance of 270µF. This capacitor is an axial leaded, non-polarized aluminum electrolytic capacitor with long life and high temperature operation. Its operating temperature range is from -40℃ to +85℃ and its endurance life is 1000 hours at 85℃ and 1700 hours at 105℃.

The working principle of the LQR2G821MSECBB aluminum electrolytic capacitor is simple. When a voltage is applied to the capacitor, the aluminum oxide film acts as a dielectric that allows electric charge to be stored. When an electric current is passed through the capacitor, the aluminum oxide fractures due to the opposing forces of the two electrodes, which enables a higher current to flow. This is the basis of how capacitors works and enables them to perform their main functions.

The LQR2G821MSECBB aluminum electrolytic capacitor offers several advantages over other types of capacitors. It has a low ESR (equivalent series resistance), low self-inductance, low leakage current, and long life. It is also able to handle very high temperatures, which makes it ideal for usage in high voltage applications. Additionally, it is able to handle very high currents and is able to store a large amount of electric charge. It is also much more compact and lightweight than other types of capacitors, making it ideal for use in portable electronics.

As far as disadvantages of the LQR2G821MSECBB aluminum electrolytic capacitor, it has a higher cost than other types of capacitors, and it is not suitable for use in low power applications. Additionally, it has large size and relatively long lead time for manufacturing. It also has a relatively short life cycle compared to other types of capacitors.

In conclusion, the LQR2G821MSECBB aluminum electrolytic capacitor is a great choice for voltage filtering and energy storage applications in high voltage and temperature environments. It offers a variety of advantages over other types of capacitors, but it also has a higher cost and limited lifetime. However, its or wide operating temperature range and its ability to handle very high currents makes it ideal for use in many applications.
