Aluminum electrolytic capacitors are a wide-ranging and important type of capacitor, ideal for applications requiring high capacitance values in a small size. Many aluminum electrolytic capacitors are marked with the letters "ETA" and numbers, such as ETA128M6R3AG6AA, which indicates to consumers and engineers the type, specifications and performance of the device. In this article, we will focus on the application and working principles of the aluminum electrolytic capacitors with ETA to explore the key features of this device.

Application field of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors with ETA are mostly used in power electronics and DC power regulation circuits, due to their low ESR and high ripple current rating. In addition, aluminum electrolytic capacitors with ETA can be used in the following applications:

• LED Lighting
• Infotainment Systems
• Communication Networks
• Power Supplies
• Power Management Solutions
• Portable Electrification Products

Working Principle of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors with ETA consists of a series of layers of aluminum foil, a thin nylon separator, and an electrolyte solution housed in a capacitor can. When exposed to a DC voltage, the electrolyte solution and the aluminum foil form an electric double layer. This double layer holds a charge for a certain period of time, depending on the capacitance of the device and the strength of the electric field. In other words, the higher the capacitance, the higher the charge held, and the greater the electric field. The capacitance of the aluminum electrolytic capacitors with ETA is determined by three variables: the area of the two aluminum foils, the distance between them, and the permittivity of the electrolyte solution between them.

The aluminum electrolytic capacitors with ETA also have a wide tolerance range, usually between -20% to +100%. This means that the device can operate effectively over a wide range of voltage, current, and temperature. In addition, due to the fact that aluminum electrolytic capacitors with ETA can be constructed with large capacitor plates and thick electrolyte, they are capable of handling higher ripple currents and can be used in high-frequency applications.

Conclusion

Aluminum electrolytic capacitors with ETA are a popular and reliable type of capacitor that are used in many industrial applications. They offer high capacitance values in a small size and have a wide tolerance range, making them an ideal choice for applications needing a reliable device. Additionally, aluminum electrolytic capacitors with ETA can handle high ripple currents and can be used for high-frequency applications. All these features make aluminum electrolytic capacitors with ETA an ideal choice for power electronics and DC power regulation circuits.
