T540D687K003BH85057610 are classified as Tantalum - Polymer Capacitors, which are useful electrical components with an extensive application field in various systems, circuits and devices. In essence, Tantalum - Polymer Capacitors are semiconductor devices that act as an electrical bridge between two elements in a circuit and regulate the current. They typically feature a metal investment to insulate the internal components from external factors and can store electrical energy for the purpose of discharging electricity at a later time.

A key application field of Tantalum - Polymer Capacitors is in large-scale data systems such as supercomputers, servers, ATM\'s and routers as they allow for the efficient transfer of large amounts of data. The use of such capacitors in these systems allows for efficient connectors which reduce the physical size of the components and ensure secure connections. Additionally, they find use in portable electronics due to their small size, high energy storage and long life spans.

The working principle of Tantalum - Polymer Capacitors lies in their construction, which relies on a unique design. At the most basic level, the electrical energy is stored in the form of an electrical field created by a special polymer material. This material is usually mounted on a single plate surrounded by an electrolytic solution, which is secured in a solid film called dielectric. This dielectric enables the electrical potential across it to be kept at a consistent level.

The electrical field created by the capacitor stores energy in much the same way as a battery. As the capacitor is filled with electric charge, the potential difference between the electric field created by the special polymer material and the negative charge of the electrons increases. As the electric charge builds up, it induces a higher potential difference between the capacitor plates. The field generated by the capacitor is then able to transfer energy between the two plates.

While being able to store energy and facilitate energy transfer, the working of Tantalum - Polymer Capacitors is not as simple as it seems. Thus, they are not suitable for all applications. For example, they cannot be used in systems that require low voltages as the electric field created by the capacitor would be too low. Similarly, they cannot be used in systems that require rapid discharge of power as the time taken for the capacitor to release its stored energy is relatively long.

In conclusion, Tantalum - Polymer Capacitors are unique components that are used in large-scale data systems and capable of numerous energy storage and transfer operations. While they present numerous advantages, their power storing and discharging capabilities are limited. Despite this, they are still a valuable asset to any electrical device, system or circuit in need of high-performance energy storage and transfer.
