Aluminum Electrolytic Capacitors: 25WA4700MEFCGC18X25 Application Field and Working Principle

Aluminum electrolytic capacitors are devices that store energy in the form of electrical charge, and they use aluminum or tantalum as electrolytes, thus making them efficient and widely used in various electronic applications. The 25WA4700MEFCGC18X25 is one of the popular aluminum electrolytic capacitors used today in high voltage applications. It is mainly used as a reverse voltage bypass capacitor in electronic circuits for voltage protection and other applications. This article discusses the application field and working principle of the aluminum electrolytic capacitor 25WA4700MEFCGC18X25.

Application Field of 25WA4700MEFCGC18X25

These aluminum electrolytic capacitors are mainly used as a reverse voltage bypass capacitor in circuits. The 25WA4700MEFCGC18X25 capacitor has an operating voltage up to 1500V, a capacitance of 4700μF, and a Capacitance Tolerance of 18%. This makes it ideal for high voltage application, mainly in industrial, automotive, and military applications, such as wide voltage range power supplies, solar systems, and scale motors. The capacitor also has enhanced surge current capabilities, ensuring the protected circuits remain operational even under high surge current conditions.

Working Principle of 25WA4700MEFCGC18X25

The working principle of aluminum electrolytic capacitors is based on Faraday\'s law of electrolysis. The capacitor consists of a stack of two conducting aluminum foils separated by an electrolyte medium. One of these aluminum foils is the anode, and the other is the cathode. When a voltage is applied across the foils, electric charge is stored on the foils, separated by the electrolyte. Thus, the capacitor acts like a battery, storing electric charge and releasing it when needed.

The 25WA4700MEFCGC18X25 capacitor has a stacked structure and contains an electrolyte layer that acts as an insulator between the two conducting aluminum foils. The anode is made of an highly conductive aluminum foil which is covered with an insulating organic material. The cathode is made of a metal oxide layer that acts as the second dielectric. When a voltage is applied across the terminals, electrons from the outer oxide layer combine with the electrolyte and move to the inner aluminum foil. This creates a charge on the inner foil that acts as the capacitor’s storage. In this way, the capacitor stores the electric charge and releases it when needed.

Conclusion

The 25WA4700MEFCGC18X25 aluminum electrolytic capacitor is an efficient and widely used capacitor in industrial, automotive, and military applications. It is mainly used as a reverse voltage bypass capacitor in circuits for voltage protection and other applications. It is designed with a high voltage rating up to 1500V and a capacitance of 4700μF. The combination of these two factors makes it ideal for high voltage applications such as wide voltage range power supplies, solar systems, and scale motors. The working principle of the capacitor is based on Faraday\'s law of electrolysis and involves the use of an electrolyte medium that acts as an insulator between two conducting aluminum foils that store the electric charge.
