Tantalum Capacitors and the F971A476MNC Application Field and Working Principle

Tantalum capacitors are an important class of electro-chemical capacitors, and they can be found in many applications. The main purpose of a tantalum capacitor is to provide a low cost, high frequency storage device using a electro-chemical mechanism. The F971A476MNC is a flagship capacitor from Murata, a renowned capacitor manufacturer.

General Principle of Operation

A tantalum capacitor is basically a solid electrolytic capacitor that consists of two structurally and electrically distinct electrodes. One of the electrodes is a solid electrolytic element made from tantalum and the other is a liquid electrolyte filled with electrolytic solution. This solution acts as an electrical conductor between the two electrodes. When a voltage is applied to the capacitor, an electric field is created across its surface. This electric field causes current to flow through the electrolytic solution, creating an exchange of ions between the electrodes. This exchange of ions is what provides the capacitor with its electrical properties.

F971A476MNC Application

The F971A476MNC capacitor is a highly reliable device, having a rated voltage of 4.7V and a capacitance of 4.7uF. It is a surface mount device, which makes it ideal in applications where space is a critical factor, such as in portable electronics. It is also designed to be highly resistant to humidity and temperature changes, making it an ideal choice for applications in extreme temperatures.

Working Principle

The working principle of the F971A476MNC is similar to other tantalum capacitors. When a voltage is applied to the device, ions from the liquid electrolyte move from one electrode to the other, thus forming a dielectric layer between them. This dielectric layer increases the capacitance of the device, thus allowing it to store a charge and act as a capacitor. As the charge is stored, the impedance of the device decreases, allowing more current to flow. The F971A476MNC is capable of operating in temperatures ranging from -55 to +85 °C and can be used in a variety of high frequency applications up to 100MHz, providing a high frequency storage device for applications where size and cost are a critical factor.

Conclusion

The F971A476MNC is an excellent choice for applications that require high frequency storage and temperature stability. Its low cost and small size makes it an ideal choice for applications where space and cost are critical factors. Its robust construction and high frequency operation make it an ideal choice for a wide range of applications, from consumer electronics to industrial applications.
