Aluminum electrolytic capacitors are a type of capacitor that makes use of an electrolyte to store and release an electrical charge. They are commonly used in consumer electronics, automotive, and other industrial applications. The EET-UQ2D821HA is an aluminum electrolytic capacitor found in many consumer electronics, particularly those with low-frequency digital signal processing (DSP). In this article, we will discuss the application field and working principle of the EET-UQ2D821HA.

Application Fields

The EET-UQ2D821HA is a surface-mount device, meant to be used in locations where space is at a premium. It is commonly used in consumer electronics, particularly those with DSP. Additionally, it is often used in automotive and industrial applications due to its high temperature range and long-term stability. The device has a low equivalent series resistance (ESR) and high capacitance size, making it particularly useful for power supplies and other higher power applications. Additionally, the device has a wide operating temperature range, making it suitable for a variety of environmental conditions.

Working Principle

Aluminum electrolytic capacitors make use of an electrolyte to store and release electrical charge. In the case of the EET-UQ2D821HA, the device consists of two aluminum foils surrounded by a thin layer of an electrolyte such as sodium hydroxide. An electric charge is applied to the capacitor plates which causes the electrolyte to become ionized. This creates a system of positive and negative ions that are attracted to the respective capacitor plates. This creates an electric field between the two plates, allowing the device to store and release electrical energy. When the charge is released, the ions recombine to form neutral molecules which then recombine with the electrolyte.

The EET-UQ2D821HA has several advantages over other aluminum electrolytic capacitors. Firstly, it has a very low ESR which allows for better power supplies and better device stability. Secondly, it has a higher capacitance size which allows for higher capacity devices. Thirdly, the device has a wide operating temperature range which allows for use in a variety of environmental conditions. Lastly, the device has excellent long-term stability which makes it reliable for a variety of applications.

Conclusion

In conclusion, the EET-UQ2D821HA is an aluminum electrolytic capacitor with a wide range of applications. It is commonly used in consumer electronics, automotive, and industrial applications. It has a low ESR, high capacitance size, wide operating temperature range, and excellent long-term stability. These features make it an ideal device for a variety of applications.
