Tantalum capacitors are advanced electronic components used in wide range of electronic circuits to increase the overall functionality of these circuits. The T491E477M010AT capacitor is a good example of such a component. This paper aims to discuss the application field and working principle of the T491E477M010AT capacitor.

A high capacitance device, the T491E477M010AT capacitor is a polymeric leaded tantalum device with a maximum capacitance rating of 4700μF (micro-farads). This device has a maximum operating temperature of 85°C, no derating required at elevated temperatures, and isdesigned to operated at voltage ratings of 3V, 6.3V, 10V, 16V, 25V and 35V, as well as a Lower ESR (Equivalent Series Resistance) of 500 mΩ. This capacitor is suitable for use in applications such as audio-video equipment, medical equipment and communications systems.

In terms of working principle, the T491E477M010AT capacitor is simply an electronic component that stores electrical charge in the form of electrical field. It does this by having two conducting electrodes (usually made of metal or metal oxide) separated by an insulating material, known as a “dielectric”. When one electrode, known as the “positive” electrode, has a higher positive potential than the other electrode, known as the “negative” electrode, the electron will flow from one electrode to the other, and the capacitor is said to be charged.

The mechanism by which the capacitor acts to store electrical energy is based on the physical principle of “capacitance”. In a capacitor, the electric field established between two conductors is the source of the energy stored, and this must be equal to the capacitance of the capacitor multiplied by the voltage. The capacitance of a capacitor is defined as the combination of the distance between the two conductors and the dielectric material between them. The capacitance is directly proportional to the plate area and inversely proportional to the distance between the two conductors.

The capacitance of the T491E477M010AT capacitor is determined by its size, the thickness and type of dielectric material used, and the distance between the two conductors. The thick dielectric material used in this capacitor provides a large level of capacitance, thus making it suitable for applications such as high-frequency switching power supply systems, DC-DC converter systems, and for power supply decoupling applications.

In conclusion, the T491E477M010AT capacitor is a highly efficient advanced electronic component designed to increase the overall efficiency of electronic circuits by providing a high level of capacitance. Its wide range of application fields and its robust design make it an excellent choice for a variety of applications. Furthermore, the device’s operational principle is based on the physical principle of “capacitance”, which states that the electric field established between two conductors is the source of the energy stored and is determined by the capacitance of the capacitor, plate area and distance between the two conductors.
