In the field of electronic engineering, aluminum electrolytic capacitors, often referred to as electrolytic capacitors, are essential components in numerous electronic devices, such as TVs, laptops, phones, and other appliances. The two main types of electrolytic capacitors are aluminum electrolytic capacitors and tantalum electrolytic capacitors. In this article, we’re going to focus on the 200USC680MEFC25X30 aluminum electrolytic capacitor and its application field and working principle.

What is an aluminum electrolytic capacitor?

An aluminum electrolytic capacitor is a component device consisting of two aluminum foils, one of which is an anode with an etched surface, and an ion-permeable membrane (also known as a separator) as the dielectric. Electrolytic capacitors are polarised, meaning that there is a difference in potential between the positive and negative terminals. The aluminum electrolytic capacitor can also be referred to as an al-cap for short.

What is the application field of the 200USC680MEFC25X30 aluminum electrolytic capacitor?

The 200USC680MEFC25X30 aluminum electrolytic capacitor is an electrolytic capacitor designed for high-frequency switching power supplies, as well as LED power supplies and high-reliability requirements applications. It has a capacitance of 680microfarads, a rated voltage of 200volts, and an ESR of 30 milliohms. The size of the 200USC680MEFC25X30 aluminum electrolytic capacitor measures 25mm x 30mm.

What is the working principle of an aluminum electrolytic capacitor?

The working principle of an aluminum electrolytic capacitor is based on the physical characteristics of electrolytes. When an electric field of sufficient magnitude is applied between the electrodes of an electrolytic capacitor, a current flows in the electrolyte, forming an electrical double layer on the surface of the catalyst particles. This double layer structure is used to store electrical energy, forming a capacitor.

Because the thin oxide film formed on the surface of the anode has a much higher dielectric constant than air, the electric energy stored per unit volume is relatively high compared with other types of capacitors. This is the reason why electrolytic capacitors are mainly used for high-capacity applications. Additionally, the small size and low cost of electrolytic capacitors make them suitable for applications where a large number of capacitors are necessary.

Conclusion

The 200USC680MEFC25X30 aluminum electrolytic capacitor is an important component in many electronic devices, due to its compact size and high efficiency. Its application field includes high-frequency switching power supplies, LED power supplies, and high-reliability requirements systems. The working principle of the aluminum electrolytic capacitor is based on the physical characteristics of electrolytes, in which an electric current forms a double layer on the surface of the anode, thus storing electrical energy to form a capacitor.
