Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most common types of capacitor used in a variety of electronic applications. They consist of two aluminium foil plates, separated by a paper or plastic dielectric, immersed in an electrolyte. Their design ensures an insulated component between the two plates with a low resistance to current flow and a high capacity for energy storage. Aluminum electrolytic capacitors are well suited for applications that require low equivalent series resistance (ESR) and high capacitance.

Features and Benefits of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors offer several advantages over other types of capacitors, such as ceramic or tantalum capacitors. The most striking feature of aluminum electrolytic capacitors is their relatively high capacitance when compared to other types of capacitors. In addition, they have a longer lifespan when compared to other types of capacitors, often providing up to twice the amount of service life. This is achieved through the capacitor’s construction, which helps to keep the surface of the aluminium plate from oxidizing and breaking down over time. Aluminum electrolytic capacitors are also known for their affordability and ease of installation, allowing for quick, easy integration into existing circuit designs.

LNR1E684MSE Application Field and Working Principle

The LNR1E684MSE is an aluminum electrolytic capacitor manufactured by AVX Corporation. It has a capacitance of 6.8uF and an operating temperature range of -40°C to +105°C. Its maximum voltage is 6.3V DC. It has a standard ESR of 0.25 ohm and is RoHS compliant. The working principle of the LNR1E684MSE is virtually the same as any other aluminum electrolytic capacitor. As previously mentioned, it has two aluminum foils separated by a dielectric material. The metal plates act as the two capacitor plates, and the dielectric material (in this case either paper or plastic) functions as an insulator between them. When a voltage is applied across the capacitor, it causes the metal to become electrostatically charged, and the dielectric material is polarised. This creates a potential difference between the two metal plates and acts as an energy storage device. The greater the potential difference (i.e. the larger the voltage applied), the greater the capacitance of the capacitor.

Conclusion

The LNR1E684MSE from AVX Corporation is a high-quality aluminum electrolytic capacitor that provides a reliable energy storage device for a variety of applications. Its 6.8uF capacitance and low ESR make it an ideal choice for applications requiring strong energy storage and high capacitance for a relatively low price. As aluminum electrolytic capacitors are an extremely common type of capacitor used in a wide variety of electronic applications, the LNR1E684MSE is an excellent choice for use in those applications.
