Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in various electronic and electrical equipment. The EKXG351ELL100MJ20S (hereafter referred to as the capacitor) is a popular model in the aluminum electrolytic capacitor family. This article will discuss the application field and working principle of the capacitor.

Application Field

The EKXG351ELL100MJ20S is primarily used in consumer electronics and industrial equipment. It is applied to different kinds of switching power supplies and DC power supplies to filter voltage ripple, such as TVs, recorders, computers and other electronic equipment. Capacitors of this type can help to reduce the noise in audio circuits, and are often used in other consumer products such as refrigerators, air conditioners, microwave ovens, and electronic heaters. The capacitor also provides a range of applications for large-scale industrial equipment, such as air compressors, pumps, motors, lathes, and other electrical machinery.

Working Principle

The working principle of the capacitors is based on the idea of oppositely charged objects attracting one another. The EKXG351ELL100MJ20S is composed of two pieces of conductive aluminum foil and a layer of dielectric paper in between. The dielectric paper impregnated with electrolyte saturates both foil plates. When an electric potential is applied to the contacts, one of the foil plates collects a positive charge, while the other collects a negative charge. This creates an electric field between the conductive plates and results in a capacitance.

The dielectric paper helps to improve the capacitance and to increase stability. A passivated aluminum oxide layer formed on the surface of the aluminum foil helps to reduce leakage. The electrolytic capacitors use a hydrogen gas to provide humidity and protection, which keeps the surface of the aluminum oxide layer clean and maintains stability.

The anode, dielectric layer and cathode form a parallel plate capacitor, which is the core capacitor structure inside the EKXG351ELL100MJ20S package. The wire connections on the capacitor are connected to the anode and cathode terminals, then the capacitor becomes an electronic component that can be used for many different electronic applications.

Performance

The EKXG351ELL100MJ20S capacitor has strong performance characteristics. Its working voltage is 100V, and its ripple current is 20 times greater than its capacitance, offering good volume performance. The operating temperature range is -25°C ~ +105°C, suitable for a variety of environments. In addition, this capacitor has a longer life of around 2000 hours at 105°C, with a ESR rating of 0.465 Ohm.

The EKXG351ELL100MJ20S also has a number of safety features for overload protection. During overload conditions, the current flowing through the capacitor will be limited, preventing it from becoming overloaded and damaging other connected parts. Additionally, it has a self-healing structure and is capable of withstanding up to 1000 volts. This ensures that the capacitor works reliably and that it is safe to use in all types of high voltage applications.

Conclusion

In conclusion, the EKXG351ELL100MJ20S aluminum electrolytic capacitor is widely used in many applications, and its performance is strong and reliable. It offers temperature ranges up to 105°C, 2000 hours of life and ESR ratings of 0.465 ohms. Its safety features and overload protection make it an ideal choice for a variety of applications in consumer electronics and industrial equipment.
