Tantalum capacitors are a type of capacitor that use tantalum as an anode. As with any other capacitor, it consists of two conducting plates (an anode and a cathode) separated by an insulating material known as dielectric. Tantalum capacitors are distinct from aluminum electrolytic capacitors as they have an anode made of tantalum. They also consist of a dry tantalum material, often manganese dioxide, sandwiched between the anode and cathode.

The T540B476K006BH86107610 capacitor is a surface mount, molded tantalum capacitor with capacitance rating of 47µF, voltage rating of 3V, and dissipation coefficient of 0.12W/°C. Its operating temperature ranges between -55°C to 125°C.

The major application field of the T540B476K006BH86107610 capacitor is in computer and medical electronics, where it is commonly used as a bypass capacitor. Bypass capacitors are used in circuits to reduce the power dissipation while the capacitor is in standby mode. The capacitor can also be used in battery chargers, automotive electronics, power supplies and communications equipment. Additionally, it may be used in high pulse applications such as laser-based technologies.

Tantalum polymer capacitors also have a much lower reverse leakage current than their tantalum electrolytic counterpart. This feature makes them well suited for low power and low voltage applications, such as RF auxiliary circuits, battery charging circuits and switching converters. Moreover, their reduced ESR (equivalent series resistance) also make them better fit for high frequency and high ripple current operations.

The working principle of a tantalum capacitor is exactly the same as any other capacitor. It produces capacitance by storing electrical charge on its plates, which are then separated by a dielectric material. This capacitance will be dependent on the shape of the capacitor, the size of its plates, and the material used for the dielectric. By varying the size and material of the dielectric a capacitor with a specific capacitance rating can be designed.

The T540B476K006BH86107610 capacitor also contains an organic polymer dielectric, making it a tantalum "polymer" capacitor. It also has a voltage rating of 3V, compared to 10V for non-polymer varieties, which makes it suitable for low voltage applications. It is one of the most popular types of surface mount tantalum capacitors available.

In conclusion, the T540B476K006BH86107610 capacitor is a surface mount, molded tantalum capacitor with capacitance rating of 47µF, voltage rating of 3V, and dissipation coefficient of 0.12W/°C. It may be used as a bypass capacitor in computer and medical electronics, low power and low voltage applications, high pulse applications and high frequency and high ripple current operations as it has a lower reverse leakage current than its tantalum electrolytic counterpart.
