Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are essential components in electrical engineering, as they are widely used in various applications due to their relatively small size and high capacitance. They are typically constructed with two aluminum foils with an oxide film on the surface as the dielectric medium. The UKT1HR22MDD1TA is one such type of aluminum electrolytic capacitor, which is characterized by its long life, high temperature resistance, and low ESR.

Application Field of UKT1HR22MDD1TA

The UKT1HR22MDD1TA aluminum electrolytic capacitor is used in a variety of applications, ranging from computers, communications equipment, and industrial machinery to appliances and automotive electronics. This capacitor is designed for use in both high-temperature and high-current applications, and its high temperature capability makes it suitable for use in environments with temperatures up to 105°C.

In addition, this capacitor has been designed to ensure a long product life. It is certified to meet the JISC-2215 and IEC 60384-21 specifications for certain parameters, and its rated lifetime of 2000 hours allows it to be used in long-term applications such as automotive power supplies.

Working Principle of UKT1HR22MDD1TA

The UKT1HR22MDD1TA aluminum electrolytic capacitor consists of two aluminum foils separated by a layer of oxide film. This oxide film acts as the dielectric medium, and it is formed by an electrochemical process. In this process, the two aluminum foils are separated and then coated with a solution containing an electrolyte. A polarizing voltage is then applied to the two aluminum foils, which causes an oxidizing current to flow through the electrolyte. This current creates a film of oxide on the aluminum surfaces, which acts as the dielectric layer.

The dielectric strength of the oxide film determines the capacitance of the UKT1HR22MDD1TA and is determined by the area and thickness of the oxide film. The capacitance of the capacitor increases with increasing area and thickness, and so does the leakage current.

The UKT1HR22MDD1TA offers excellent capabilities and high reliability for a wide range of applications. Its long life, high temperature resistance, and low ESR make it ideal for use in high-temperature, high-current applications. In addition, its rated lifetime of 2000 hours is more than enough for many long-term and heavy-duty applications.
