T491V156M025AT is one of a type of tantalum capacitors. Tantalum capacitors are also called solid electrolytic capacitors. They are considered to be superior to ceramic capacitors as they have high temperature stability and high capacitance for their size. They are commonly used in high voltage applications, such as in high voltage DC-DC converters, power supplies, and other high voltage circuits.

T491V156M025AT is a type of radial leaded tantalum capacitor. They are designed for surface mount applications and have a low profile package. The capacitance of this type of capacitor is 156 μF at 25 VDC. It has a maximum operating temperature of 125°C, a maximum ripple current of 1.2 A rms, and an endurance rating of 5000 hours at rated voltage and temperature.

The working principle of a tantalum capacitor is based on the oxidation-reduction property of tantalum. In this process, when a charge is applied to the capacitor, the metal oxide layer on the surface of the tantalum acts as an electrolyte and forms a dielectric layer between the plate and the surface. This movement of charge creates a capacitance between the two plates. As a result, it stores the electric charge in the form of an electric field.

T491V156M025AT capacitors are used in many electronic applications. These applications include power supply decoupling, filter circuits, high-frequency switching, switching regulating, and voltage boosting. They are also used in analog circuit designs such as pulse circuits and filter designs, and for interference suppression and bin in power grids.

The use of tantalum capacitors as components in electronic applications has increased significantly in recent years. This is due to their ability to store greater amounts of charge in a small package. They also offer excellent frequency response and temperature stability. This makes them ideal for use in high-temperature and rapid-update electronic applications.

Tantalum capacitors can be manufactured in both axial and radial configurations. The package size varies from medium to large to accommodate different applications. Tantalum capacitors are highly reliable and are suitable for volume production. They also offer a wide range of temperature characteristics and voltage ranges.
