Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (also known as aluminum electrolytic variable capacitors) are the most commonly used type of capacitors, widely used in various types of electronic equipment.EEL-1EA220WAR, also known as a "Super Capacitor", is a new type of ultra-small-size aluminum electrolytic variable capacitor specifically designed for use in high-frequency switching power supply applications.

Applications

EEL-1EA220WAR capacitors can be used in high-frequency switching power supply circuits, step-up and step-down circuits, etc., to meet the requirements of fast charging and discharging.In addition, due to its small size and large capacity up to 220uF, EEL-1EA220WAR capacitors can be generally used in vibration-resistant, anti-interference, and power saving applications.

Working Principle

EEL-1EA220WAR capacitors use the principle of electrolysis to store and release electric charge.Aluminum electrolytic capacitors consist of electrodes, a dielectric layer consisting of aluminum oxide deposited on the aluminum foil, and electrolyte.The capacitor\'s anode and cathode are two pieces of aluminum foil that are etched and crimped to form a capacitor. During the etching process, microscopic pores are formed in the aluminum foil that act as channels for the electrolyte to infiltrate the aluminum oxide layer. When a voltage is applied across the anode and the cathode, an electric field is created across the dielectric layer. This electric field repels the negative ions of the electrolyte, allowing positive ions to pass through to form an electrical bridge between the anode and the cathode. This electrical connection allows electric charge to be stored in the capacitor and then released when the voltage is reversed upon discharge.

Conclusion

EEL-1EA220WAR capacitors are an ultra-small-size aluminum electrolytic variable capacitor specifically designed for use in high-frequency switching power supply applications.It can be used in a variety of applications such as vibration-resistant, anti-interference, high-frequency switching power supply, and power saving. The working principle of these capacitors is based on the principle of electrolysis and is composed of a dielectric aluminum oxide film, electrodes and electrolyte, which allows electric charge to be stored and then released when the voltage is reversed upon discharge.
