T540B107M004DH87107280 is a form of tantalum-polymer capacitor and is a surface-mountable electrochemical capacitor. This type of capacitors can store relatively large amounts of electrical energy, but are only suitable for low voltage applications and should not exceed the rated voltage of 4.5 V. Tantalum-polymer capacitors offer a number of advantages over ceramic capacitors and are commonly used in applications such as pulse handling, power supplies and signal processing.

Tantalum-polymer capacitors have a liquid electrochemical process in their construction which results in high capacitance and ESR ratings. The capacitance of the polymer is determined by the resistance of the material and its total capacity or surface area exposed to the electrolyte ions. The metallic tantalum core provides energy when required and helps maintain stability in the electrical system. Compared to ceramic capacitors, tantalum polymer-capacitors can give up to ten times better electrical performance for smaller size and same capacitance.

Much of the performance of this type of capacitors is dependent on the workmanship of the assembly and the overall quality of the components used in their construction. To ensure consistent quality and a long life, all capacitors should be appropriately screened and tested. In addition, careful attention must be paid to the rate of increase in temperature during operation and the maximum temperature rating should not be exceeded.

The working principle of tantalum-polymer capacitors is based on a combination of Tantalum and polymers in their construction. When a voltage is applied, the polymers in the capacitor expand and cause a higher capacitance, while the electrical resistance of the organic electrolyte is increased. The increased capacitance is the result of the increased charge created by the polymer expansion. At the same time, the electric field from the applied voltage causes an electric current to be induced in the capacitor, which is transported by the ions in the liquid electrolyte.

The electrons in the liquid electrolyte travel through the networks of the metallic tantalum core, driven by the electric field of the applied voltage. During the process, the electrons lose kinetic energy resulting in the production of heat, which further increases the capacitance of the capacitor. Meanwhile, the ionic wave produced by the motion of the electrons creates an electromagnetic field which results in a higher performance of the capacitor.

The large capacitance of tantalum-polymer capacitors makes them an ideal choice for energy storage applications, pulse handling, power supplies and signal processing. The ability to quickly store and deliver a large amount of energy makes them well suited for low-voltage applications. In addition, their small size and low-cost makes them well-suited for use in the automotive, medical and military electronics industries.

Tantalum-polymer capacitors offer unique advantages over other capacitor types, including better electrical performance, higher reliability, smaller size, lower cost and longer life. Most types of polymer capacitors offer better performance in smaller packages than their ceramic counterparts. By combining a high-capacity electrode with a low-resistance organic electrolyte, polymer capacitors deliver a high capacitance rating with excellent stability and reliability.
