Introduction

Aluminum Electrolytic Capacitors (EKXJ201ELL271MU40S) are components that are widely used in electrical and electronic circuits. They are available in a wide range of sizes and values and are used for a variety of purposes. In this article, we will discuss the application field and working principle of the EKXJ201ELL271MU40S aluminum electrolytic capacitor.

Application Field

Aluminum electrolytic capacitors with EKXJ201ELL271MU40S designations are typically used in the automotive and industrial markets. They are typically found in circuits where high values of capacitance are required. Of specific interest are applications calling for low equivalent series resistance (ESR). This type of capacitor is also found in high-quality audio systems where high capacitance values and low ESR are essential for proper operation.

Working Principle

The operation of an aluminum electrolytic capacitor is based on the principle of electrochemical double-layer capacitors (EDLC). The construction consists of an anode (anode) formed from aluminum foil and a cathode (cathode) comprising a permeable paper film soaked in an electrolyte. A thin film of oxide, known as insulating dielectric, is formed on the aluminum foil when it passes through an oxide-forming process. When a voltage is applied, the oxide layer absorbs the charge, forming an electric double layer and thus allowing the capacitor to store electrical energy.In order for the capacitor to operate properly, the oxide layer must remain intact and be able to withstand the voltage applied. To ensure this, the electrolyte must be selected to meet the desired voltage and temperature requirements.

Conclusion

In conclusion, aluminum electrolytic capacitors with EKXJ201ELL271MU40S designations are widely used in automotive and industrial applications. They are used to store electrical energy with the help of an insulating dielectric oxide layer and an electrolyte. Careful selection of the electrolyte is necessary to ensure the oxide layer is able to withstand the voltage applied and provide the desired performance.
