Aluminum electrolytic capacitors, also known as electrolytic capacitors, generally refer to capacitors made of an anode of aluminum foil, oxidized to form a porous insulating layer, and coated with a solid electrolyte. They are widely used in the fields of radio and communication, electrical engineering, and industrial control due to their small size, large capacitance, and low price. Today, aluminum electrolytic capacitors have become the indispensable component in many industrial production lines and their application fields have been greatly expanded.

The UPW2C2R2MED1TD aluminum electrolytic capacitor, with its rated voltage of 2 V and a rated ripple current value of 2 mA, is a so-called low resistance and low impedance aluminum electrolytic capacitor. It is mainly used in electronic circuits requiring low temperature drift voltage and low impedance with extremely low ESR. Moreover, due to its capacitor shell made of stainless steel plates, it is not prone to be corroded by moisture and dust, making it suitable for special occasions, including wet and dusty production sites.

The working principle of UPW2C2R2MED1TD aluminum electrolytic capacitor lies in the nature of the oxide layer formed on the aluminum foil via an anodic oxidation process. During this process, oxygen molecules are released from the anode and penetrate into the interior of the oxide layer repeatedly, creating a large number of oxygen vacancies. These oxygen vacancies have an anisotropic distribution, thereby forming an electric field in the oxide layer. In the meantime, an anion-conductive path is created through the electric field, allowing electrons to move freely. When a voltage is applied, the anions in the electrolyte are attracted by the electric field and further stored at the surface of the anode. In this way, the UPW2C2R2MED1TD aluminum electrolytic capacitor can be used as a ‘condenser’ for electricity as it capacitates electrical charges on the two plates in opposite directions.

In summary, UPW2C2R2MED1TD aluminum electrolytic capacitors are mainly used in electronic circuits requiring a rated voltage of 2V and a rated ripple current value of 2mA. Due to its capacitor shell made of stainless steel plates and its low temperature drift voltage and low impedance with extremely low ESR, UPW2C2R2MED1TD aluminum electrolytic capacitor is ideal for special production sites that are wet or have a high dust concentration. Its working principle lies in the properties of the oxide layer formed on the aluminum foil, which exhibits an electric field, forming an anion-conductive path that allows electrons to move freely and allowing the capacitor to store electrical charges on the two plates.
