Working Principle

Tantalum - polymer capacitors have a working principle that is similar to that of traditional electrolytic capacitors. They use a dielectric material, such as Tantalum, as the base material for the capacitor. A polymer layer is then applied to the two electrodes, forming an electrochemical cell. When the capacitor is powered, an electric current is passed through the tantalum layer, causing a chemical reaction that forms a crystal lattice in the dielectric. This crystal lattice creates a barrier that prevents charge from passing through, resulting in the capacitor storing energy.

The F381A475MMA capacitor offers a number of features that make it well suited for use in high frequency switching and power supply applications. It has a high capacitance rating, providing excellent capacitive energy storage capabilities. It also has an ultra-low ESR value, which ensures that the capacitor is able to dissipate heat efficiently and perform with minimal power losses. Finally, its low equivalent series resistance (ESR) also contributes to an improved power supply ripple control characteristics.
