Aluminum Electrolytic Capacitors are capacitors that use an oxide film of aluminum foil as an insulating layer, with a paper or metal separator to prevent its oxidization. They are the most commonly used type of capacitor due to their low cost, high power capacity, and higher temperature and voltage ratings. The EEU-ED2E820S capacitor is a type of surface-mount aluminum electrolytic capacitor that offers a wide range of features and benefits.

The EEU-ED2E820S is available in a range of capacitance values ranging from 0.47uF to 100uF, with tolerance range of ±20%. It has a maximum operating temperature of +105°C, and a Rated Voltage of 6.3V. The capacitor is also specified for short-term operating voltage of 10V, with a temperature life of 2000 hours at room temperature. This makes it ideal for use in a variety of applications.

The capacitor is widely used in automotive and entertainment equipment, as well as other high performance applications. It is often used for applications that require high ripple current, such as power supplies used in light-emitting diode (LED) lighting, mobile phones, and computers. It is also suitable for power tools, cameras, and audio amplifiers. With its wide capacitance range and high temperature rating, it is suitable for applications where large capacitance values and high temperature ratings are required.

The working principle of aluminum electrolytic capacitors is based on Faraday’s law of electrolysis. When an electric current is passed through an electrolytic solution containing metallic ions, an electrolytic current is produced based on the differences in potential between the positive and negative electrodes. This leads to the formation of metallic films on the surface of electrode, in the case of the EEU-ED2E820S, aluminum oxide films. The electric charge stored in these films creates a capacitive effect, and this is what is used to store and release electrical energy in a controlled way.

The oxide films also act as a protective layer for the aluminum foil, helping to prevent it from oxidation. This helps to ensure that the capacitor can maintain its capacitance even in high temperature and humidity environments. The EEU-ED2E820S is rated at a life expectancy of up to 2000 hours under normal temperature and operating conditions, so it can be relied upon to deliver reliable performance, even in demanding applications.

In conclusion, the EEU-ED2E820S capacitor is a reliable and robust aluminum electrolytic capacitor with a wide range of features and benefits. It is suitable for a variety of applications, and its high temperature and voltage ratings make it well-suited for use in high performance systems. Its capacitance range and long-life expectancy make it an excellent choice for a variety of projects.
