Tantalum Capacitors: F721C476MRC Application Field and Working Principle

Tantalum capacitors, also known as conformal coated tantalum capacitors, are a type of capacitors with a construction based on tantalum metal, an element from the periodic table. Capacitors are electrical components designed to store electric energy, releasing it when the current. These capacitors are used in virtually all types of electronic equipment due to its size, high capacitance and low loss. Part of their appeal is their small size and light weight, making them perfect for applications in which space or weight are an issue.The F721C476MRC is a type of conformal coated tantalum capacitor. This specific device is a surface-mounted electrolytic capacitor with an anode-to-cathode voltage of 4 VDC. It has a capacitance of 47µF and a low ESR of 40 mOhms. Its temperature range is from -55 to 125 degrees Celcius. The F721C476MRC is mainly used in applications that require a high-reliability and low-profile solution, such as in portable electronics like cell phonesGPS systems, personal digital assistants (PDAs)MP3 players, and others.The working principle of the F721C476MRC is based on two dissimilar conductive layers, the anode and the cathode, separated by an insulator. When a voltage is applied, the electric charge is accumulated between the two electrodes, resulting in an electric field. The capacitance is a measure of the amount of electric charge that can be stored between the two electrodes of the capacitor. As the applied voltage increases or decreases, the discharge or charge of electric charge can be controlled.The F721C476MRC features a conformal coating that provides protection from dust and contaminants and to help prevent the release of gas from the capacitor’s internal elements. This helps to extend its operational life and reliability. Additionally, it has high capacitance density, allowing for a small size even when relatively large capacitances are required for the application.The F721C476MRC is also capable of withstanding extreme environmental conditions such as exposure to shock, vibrations, ambient temperatures and humidity. As such, it can handle the rigorous demands of some industrial and military applications. It is also RoHS compliant and offers excellent thermal, voltage and aging stability.In conclusion, the F721C476MRC is a surface-mount tantalum capacitor offering considerable advantages over other types of capacitors. Its features make it ideally suited for use in portable, military, and industrial applications. Its working principle is based on the accumulation of electric charge between an anode and a cathode, and its conformal coating provides additional protection against the elements. The F721C476MPR is a reliable and dependable device, making it a popular choice among users.
