Tantalum capacitors are electronic passive components composed of tantalum and manganese dioxide, which are fabricated and maintained in the form of a solid-state capacitor which has some advantages over the other types of capacitors, such as their higher density, reliability, and cost effectiveness. The F971A475KAA is a tantalum capacitor in the form of a radial dipped capacitor. The capacitance ranges from 1μF to 100μF and it has a voltage rating of 16V to 20V. The operating temperature ranges from -55℃ to +125℃.

Application Field of F971A475KAA

The F971A475KAA tantalum capacitor is specifically designed for applications where miniature sizes are required. This capacitor is used in computer and storage devices, TVs, large LCD TVs, car audio systems, video players, medical instruments and equipment, military equipment, cell phones, portable audio and video systems and other consumer electronics.

Specifically, the F971A475KAA can be used in applications such as filtering, signal bypassing, and energy/power storage. It is used for signal bypassing in digital computers, as it is much more reliable than ceramic capacitors. Its filtering function is also necessary for switching power supplies and electronic circuitry, as it provides stable impedance characteristics. As for energy/power storage, the capacitance combined with high temperature stability ensures the safety of electrical systems.

Working Principle of F971A475KAA

Tantalum capacitors are made up of two electrodes: a tantalum anode (positive electrode) and a manganese dioxide cathode (negative electrode). The capacitor has a layer of insulating material in between them which when energized, allow electric charges to move back and forth between the electrodes. When connected in a circuit, they act as a storage device, storing and releasing electric charges.

The F971A475KAA works similarly to other types of capacitors, where an electric current is drawn from one of the electrodes to the other. The amount of current drawn depends on the amount of capacitance present. This is determined by the size of the electrodes and the type of insulating material. The capacitance is also affected by the temperature, as higher temperatures result in higher capacitance.

The F971A475KAA capacitor also has a low effective series resistance (ESR) and high dielectric strength. This ensures that the capacitor can handle large amounts of current with minimal losses. The low ESR also ensures high-performance and stability, as well as improved circuit performance.

Summary

The F971A475KAA capacitor is a radial dipped tantalum capacitor that has a capacitance ranging from 1µF to 100µF, and a voltage rating of 16V to 20V. Its temperature range is -55℃ to +125℃.
