Aluminum Electrolytic Capacitors

Introduction

Aluminum electrolytic capacitors are electronic components used to store electrical charge and are widely used in electrical and electronic systems. They feature an electrolyte made of a substance such as an aluminum oxide film which serves as an insulating and charge storing layer between two metal plates. They are general purpose capacitors and are used mainly in the filtering and decoupling circuits.

LNR1K683MSE Application Field and Working Principle

The LNR1K683MSE is an aluminum electrolytic capacitor from Nichicon. It has a capacitance value of 6.8uF and a voltage rating of 25V. The LNR1K683MSE is widely used in various applications ranging from power supplies, automobiles, sound equipment, home appliances, measurement and test equipment, Medical devices, and others. The working principle of the LNR1K683MSE is based on the Faraday’s Law of Electrolytic Capacitance. According to this law, the capacitance, C of the capacitor is determined by the following formula: C = ε A/dWhere, ε= dielectric constant of the insulator/electrolyteA = surface area of the plates d = distance between the two platesWhen a voltage is applied to the plates of the capacitor, un-ionized molecules in the electrolyte become ionized due to the high electric field. This reduces their dielectric strength and increases their electrical conductivity. As a result, a strong electric field is set up between the plates and the capacitance increases. This applied voltage is then stored between the plates of the capacitor.

Conclusion

The LNR1K683MSE aluminum electrolytic capacitor is a widely used device for various applications. Due to its high capacitance value and voltage rating, it is suitable for a wide range of applications. It is used mainly in power supplies, automobiles, sound equipment, home appliances, measurement and test equipment, medical devices, and others. Its working principle is based on Faraday’s Law of Electrolytic Capacitance and it can store electric charge when a voltage is applied to its two metal plates.
