Tantalum capacitors are one of the most widely used types of capacitors in the electronics industry. Their capacitance is high, and they can withstand a wide range of temperatures, allowing them to be used in a variety of applications. The F931D475MAA is a popular tantalum capacitor for such applications.

The F931D475MAA is a solid-state electrolytic capacitor with a voltage rating of 6.3V. It is available in many sizes, from 0805 (imperial or metric) to 1206 (metric only). The capacitance range is from 0.1µF to 47µF. It features a voltage dependent failure rate of less than 0.01% per thousand hours (at its rated voltage). It also has a very low equivalent series resistance (ESR) of 0.2Ω. As with most tantalum capacitors, the F931D475MAA is constructed with solid tantalum as the anode material, which makes it quite reliable and stable.

The F931D475MAA is primarily used in low voltage power supplies, where it can be used to filter out voltage spikes and prevent damage to sensitive circuitry. The high capacitance makes it suitable for energy storage and storage of power when needed. The low ESR ensures that the voltage stored is rapidly discharged, which is beneficial in power supplies.

The working principle of the F931D475MAA is essentially the same as any other tantalum capacitor. When voltage is applied to the capacitor, ions from the anode material form a "double layer" between the capacitor plates. This causes the plates to become electrically charged and thus store energy. When the voltage is removed, the ions migrate back to their original positions and the stored energy is released.

The F931D475MAA is a popular choice for many electronic applications due to its high capacitance, low ESR, and voltage-dependent failure rate. It is well-suited to low-voltage supplies and is often used in the filtering of voltage spikes. Its reliable, robust construction ensures a long service life.
