EKMR251VSN821MQ40S

Aluminum Electrolytic Capacitors are a type of capacitors used in a wide range of electronics applications. They are commonly used for power supplies, signal conditioning, and voltage regulation. The EKMR251VSN821MQ40S is an aluminum electrolytic capacitor manufactured by Kyocera Corporation. The model number identifies the size, electrical characteristics, and other details of the capacitor.

The EKMR251VSN821MQ40S is a miniature, low-impedance aluminum electrolytic capacitor. It is capable of handling high temperatures up to 85°C for a long period of time without reduced performance. The capacitor has a low-resistance path, which makes it suitable for power supplies and other applications that require low resistance. Its nominal capacitance is 0.22 μF (micro-Farad), with an allowed variation from -10% to +20%. The rated operating voltage is 16Vdc.

The main difference between the EKMR251VSN821MQ40S and other aluminum electrolytic capacitors is its low impedance. Its low-impedance performance makes it ideal for applications that require high frequencies and increased power stability. The low impedance also results in longer life expectancy. The capacitor can withstand high temperatures up to 85°C, making it ideally suited for use in power supplies and other applications that require higher temperatures.

The working principle of aluminum electrolytic capacitors is based on the principle of electrolysis, in which an electric current is passed through an electrolytic solution. This results in the formation of two separate layers of metallic ions, with one layer forming on the surface of the capacitor and the other layer ionizing the electrolyte inside the capacitor. The two layers create an electrochemical effect, causing a charge to be stored on the capacitor plates. This charge can then be used to supply voltage or current to various electronic circuits.

In the case of the EKMR251VSN821MQ40S, two metallic plates are placed in the electrolyte, along with an oxide layer between them. When electrical current is passed through the two plates, an electrolytic reaction takes place, resulting in a build-up of charge on the plates. The oxide layer acts as a dielectric, helping to keep the charge stored on the plates. This charge can then be used to supply power or current to electronic circuits, depending on the specific application.

Aluminum electrolytic capacitors, such as the EKMR251VSN821MQ40S, are used in a wide range of electronic applications. These include power supplies, signal conditioning, voltage regulation, and noise suppression. They are also used in motor control, LED lighting, and reactive filter circuits. Due to their low impedance and robust construction, aluminum electrolytic capacitors are often the preferred choice in many electronics projects.
