T491B475K020AT is a member of high-performance family of Tantalum Capacitors. Its low ESR and ultra-high capacitance make it suitable for various modern electronic designs. Its unique chemical composition and construction make it suitable for high-temperature, low-leakage, and high-reliability applications. The high-temperature capability combined with a low beta, makes it one of the most desirable capacitors in today\'s electronics market. Its broad range of features and performance also makes it suitable for various applications.

A tantalum capacitor is a type of electrolytic capacitor, which consists of two conductive plates separated by an electrolytic solution made up of a tantalum alkoxide. It is the only type of electrolytic capacitor that has a metal dielectric, which has a significantly higher permittivity than other metal dielectrics. Due to its high temperature stability, low ESR, high operating temperature, and low leakage current, it is widely used for high-temperature and low-leakage applications.

T491B475K020AT for instance has a 72uF/35V rating and a very low ESR (equivalent series resistance) of 0.24 ohms. This makes it suitable for use in high-temperature and high-reliability applications such as automotive, industrial, military, and aerospace applications. It is also suitable for use in computer mainboards, motherboards, server boards, and hard disk drives.

The working principle of Tantalum Capacitors is based on the principle of electrochemical action. The two electrodes are separated by the tantalum electrolyte, and when an electric field is applied across the electrodes, ions from the electrolyte move towards the opposite electrodes and electrolyte eventually moves from one side of the capacitor to the other. This action produces an electric current, which is transported from one terminal to the other. The movement of the electrolyte also generates heat and creates expansion which helps in maintaining the equilibrium of energy.

T491B475K020AT is considered to be the best choice for medium- to high-temperature, long-term, high-precision and high-reliability electronic applications. Its features, including small size and low ESR, make it particularly suitable for applications such as low-voltage power supplies and power bus converters. It is also suitable for use in a variety of automotive, space and military applications, as well as in computers, telecommunications, and consumer electronics. Its wide range of handling and stability make it ideal for powering modern high-end microprocessors.

The construction of the capacitor provides excellent heat dissipation properties. The T491B475K020AT is designed with a capacitor body that is resistant to thermal shock and vibration. This design also helps to reduce the temperature coefficient of capacitance and is effective in conserving energy.

Due to its low ESR and high temperature performance, the T491B475K020AT has become a popular choice for many applications. Its wide range of features, small size, and low ESR makes it ideal for high-precision, long-term, and high-reliability electronic products. Its unique chemical composition and construction make it suitable for a wide range of applications including automotive, space, military, and consumer electronics.
