Tantalum capacitors are an important subcategory of electrolytic capacitors. They are constructed from tantalum metal and usually covered with an insulating coating. Tantalum capacitors are much smaller in size than standard electrolytic capacitors, making them ideal for use in miniature electronic devices. Additionally, they have very low ESR (equivalent series resistance) which makes them very efficient in a large range of operating temperatures.

The model T520V227M2R5ASE012 is part of the tantalum – polymer capacitor family. It consists of two electrodes, with optical separation between them. The capacitance of a T520V227M2R5ASE012 capacitor is measured in farads, and its rated value can range from 220uF with a 6.3V voltage. The ESR for this capacitor is less than 0.750 ohms at 25°C. Moreover, the lifetime at rated voltage and temperature is more than 2000 hours.

The main application fields of the model T520V227M2R5ASE012 tantalum-polymer capacitors are automotive and industrial circuits, asthey are able to handle high temperatures, electrical stresses, and outgassing. Some of their common uses include decoupling, filtering, and for bypassing.

A schematic representation of the operating principle of a T520V227M2R5ASE012 is pictured below. It is a layered structure consisting of a tantalum-conductive polymer composite, the dielectric (insulating) layer, and the two electrodes connecting the capacitor to the circuit. When a voltage is applied across the two electrodes, a charge is stored in the tantalum-polymer composite layer, inducing a positive electric field between the two electrodes.

When a sudden change in voltage is applied, the current or charge is then transferred between the two electrodes. This process is known as capacitance, and it is what a capacitor does when it stores or releases charge. The magnitude of the charge stored within the capacitor can be determined by the equations below, where C = Capacitance and V = voltage:

C = (A·d)/k

V = Q/C

Due to their small size, high capacity, high stability, and efficiency in extreme temperatures, the tantalum-polymer capacitors are widely used in many electrical and electronic products.
