Aluminum electrolytic capacitors are widely used in various electrical and electronic fields such as computer, communication, aviation, household appliances, industrial control and so on due to their advantages such as high energy density, small size, large capacity, low price, long life and high performance. EET-UQ2D122KA is one of them. This paper introduces its application field and working principle in detail.

Application areas of EET-UQ2D122KA

EET-UQ2D122KA is a low-ESR, high-capacity aluminum electrolytic capacitor. This capacitor is energy-saving and highly efficient, and is mainly used in computer power supplies, including DC/DC converters, DC ovens, and other equipment. In addition, EET-UQ2D122KA can also be used in notebooks, servers, LCD monitors, amplifiers, and other special electrical applications.

Working principle of EET-UQ2D122KA

EET-UQ2D122KA mainly consists of an aluminum case, electrolyte, cathode and anode, separator and lead-out terminal. The anode is made of pure aluminum foil. The electrolyte used is a manganese nitrate solution based on (protective electrolyte). The electrolyte has high thermal stability and high insulation performance. The separator is made of insulating paper. This paper is soaked with electrolyte and functions as insulation and a barrier to prevent short-circuit between electrodes.

When being electrified, aluminum composition combines with oxygen ions, hydroxyl and impurities to form a porous anode film. The inner layer of the film is the contact area between electrolyte and aluminum sheet. The outer layer is mainly composed of aluminum oxide, which is a capacitor dielectric. The contact area of electrolyte and aluminum sheet itself is very small, its dielectric is very large, and the capacitance of electrolyte also increases.

The electrical field generated on the surface of anodic film will cause positive ions in electrolyte to migrate to the anode. At the same time, negative ions migrate to the cathode side. This is how the current is stored by EET-UQ2D122KA capacitor. When there is no electricity, it can be discharged within a certain time.

In conclusion, EET-UQ2D122KA is an energy-saving and efficient aluminum electrolytic capacitor for computer power supplies. Its working principle is that the anode film is formed in the presence of electric field to achieve the storage of electricity.

With development of technology, the application area of EET-UQ2D122KA continues to expand. Compared with other capacitors, it has the advantages of small size, light weight, stability and high performance. Therefore, it is quite promising in different electronic applications.
