Introduction

Aluminum electrolytic capacitors (or ALCs) are widely used in many applications, such as in power supplies, in consumer electronics, and in industrial equipment, and they are available in a variety of different form factors and capacitance values. The UES1A221MPM1TD is a distinctive type of ALC that is suitable for use in higher voltage applications such as those found in automotive, telecommunications, and medical industries.

Application Field

The UES1A221MPM1TD is specifically designed for applications that require higher voltage performance than offered by standard ALCs. It can handle peak voltage of up to 25V and a maximum continuous voltage of 21V, making it well-suited to environments where present and future voltage needs may exceed the maximum rating of off-the-shelf ALCs. It is ideal for use in applications such as automotive, telecommunications, and medical industries, where higher performance capacitor solutions are required.

The UES1A221MPM1TD is also well-suited to power supply applications, as it is designed to handle ripple current of 2A without undue strain on its components. It is also able to operate at temperatures as high as 105°C, making it an excellent choice for applications that must operate at higher temperatures than standard ALCs can handle.

Working Principle

Aluminum electrolytic capacitors operate by using an electrolytic solution to store an electrical charge. This charge is stored between two layers of aluminum oxide, formed on the surface of two plates of conductive aluminum. The capacitance of the device is determined by the area of the plates, the type of oxide coating, and the size and nature of the electrolyte used. The electrolyte also allows ions to move between the two oxide layers, allowing for the storage of energy.

The UES1A221MPM1TD is constructed with a hermetically sealed, organic-polymer-type electrolyte. This structure ensures that the capacitor is less prone to leakage current and widely considered to be one of the most reliable types of ALCs available today. Additionally, the electrolyte is designed to have a low dielectric absorption coefficient, giving the capacitor a good temperature stability rating.

Conclusion

The UES1A221MPM1TD is an excellent option for applications that require higher voltage performance than offered by standard ALCs. It has good temperature stability, low leakage current, and can operate in temperatures up to 105°C. With these features, it is an ideal choice for automotive, telecommunications, medical, and power supply applications.
