T491D106K050AT2478 is a type of tantalum capacitor. It belongs to the group of polarized capacitors, along with aluminum electrolytic capacitors, and is most notably used in the power supply smoothing and filtration applications.

In the electric equipment, the tantalum capacitor has to bear the switching pulse energy stress, and has the characteristics of high voltage strength, good pulse endurance, low loss, good temperature stability, wide frequency response range and so on. Thus, these capacitors are used in a variety of electronic equipment, such as DVD player, rectifiers, high-frequency oscilloscopes, satellite television systems, and even the Mars Rover.

Generally, it consists of a tantalum pellet connected between two pins, serving as electrodes with oxide dielectric layer, and covered with a rigid epoxy. The case is filled with a liquid electrolyte, named manganese dioxide, providing the required electric conductivity from anode to cathode.

The scope of the T491D106K050AT2478 application fields includes determining circuit impedance, filtering in a signal or AC power line, adjusting and controlling the electric current in a circuit, and supplying power for a system. It also functions as noise reduction in audio applications, protecting electronic components from voltage transients, and providing energy storage.

In terms of working mechanism, the T491D106K050AT2478 is a capacitors that stores the electric potential energy and forms a charge separation across its plates. The amount of charge that can be held is dependant on the capacitance value, the dielectric material, and the area and separation between the plates. The charge separation across the plates alters the electric field, allowing current to flow where it would not otherwise.

In order to run, this capacitor needs two external stable voltage sources. Firstly, the charges are added to the capacitor by an external source to create a potential difference between the two plates and build up a charge in the plate. The amount of charge held in the capacitor\'s plates decreases as the external source is removed. As the capacitor reaches full charge, the chances of current flow reduces until there is no current flowing.

T491D106K050AT2478 tantalum capacitors are proving to be very useful devices in the modern electrical engineering. It has a wide range of applications in various kinds of electronic systems and circuit protection. This type of capacitor is impressive for its robustness, as well as its high voltage strength, and its excellent ability to filter signals and AC power lines.
