Aluminum electrolytic capacitors are capacitors that use an oxide layer on a pure aluminum sheet as the dielectric. They are made to store and release energy using an applied electric field to charge a thin anode layer of aluminum foil with a high amount of chemical energy. The oxide layer is a thin coating of a material that resists electrical current. The capacitance of this collision-loaded capacitor is much higher than that of any other type of capacitor, including ceramic, paper, and tantalum capacitors.

EKMH161VNN391MR20T is an aluminum electrolytic capacitor that is suitable for use in a variety of applications. It is a non-polarized capacitor, meaning that either one of the two connections can be used as the ground or positive voltage. The EKMH161VNN391MR20T is also a high-temperature type capacitor, meaning it is made to withstand and function in high temperatures without loss of performance or life. This capacitor features a capacity of 220µF/ 500Vdc and a maximum operating temperature of 135°C.

The application field and working principle of EKMH161VNN391MR20T stem from the fact that it is an aluminum electrolytic capacitor. Its main applications center around power supplies and filtering applications. In power supplies, aluminum electrolytic capacitors are used to store and release energy on a recurring cycle as required by the application. This relevancy of energy helps power supplies to achieve their desired output levels. Filtering applications, on the other hand, rely on aluminum electrolytic capacitors to condition electrical signals to meet certain applications’ needs. In this instance, the capacitor acts as an AC filter, and can reduce noise and other distortions in the signal.

The technical working principle of EKMH161VNN391MR20T is based on its aluminum electrolytic construction. As discussed earlier, an oxidized aluminum foil and an electrolytic solution are sandwiched between two sheets of aluminum foil. When a voltage is applied across this capacitor, an electric field is created that induces the oxidation of the aluminum sheet on the anode side. This oxidation layer undergoes a chemical reaction with the electrolyte solution, which creates a surface charge. When the electric field is reversed, the surface charge attracts a second charge in the opposite direction, creating a potential difference between the two charges. This potential difference is then stored in the dielectric layer, acting as the energy storage(i.e capacitance) for the capacitor.

EKMH161VNN391MR20T is an aluminum electrolytic capacitor that is suitable for a variety of applications, such as power supply, filtering, and other high-temperature applications. Its technical working principle is based on the anodic oxide layer created on the aluminum sheet, as well as the reversing electric field that attracts charges in opposite directions and creates a potential difference in the dielectric layer. As such, the EKMH161VNN391MR20T is an effective and reliable energy storage solution for a variety of applications.
