Tantalum Capacitors

Tantalum capacitors are one of the most common type of capacitors used in electronics today and are named for their main electrolyte material; tantalum. They are much smaller than their electrolytic counterparts and are used for a variety of applications such as filtering and noise suppression, AC-to-DC conversion, timing delays and stabilization of oscillators.

The most common design for a tantalum capacitor is a cylindrical metal can with two leads. Inside the can is a wrapped tantalum metal pellet coated in conductive oxide. The capacitor is filled with liquid electrolyte, which serves as the medium of energy flow. When charged, further oxide is formed and it covers the metal pellet, forming a dielectric layer and creating a strong pseudo film.

The particular capacitor model in question is the 298D107X06R3P2T. This is a miniaturized, solid tantalum capacitor with a high capacitance (47µF), low equivalent series resistance (8.2 mO) and an operation temperature range from -55 to +125 °C. It is designed for both through-hole and surface mount applications with a size of 2.5 x 2.1mm.

The main application for the 298D107X06R3P2T capacitor is decoupling and energy storage. When used in decoupling technology, they act as miniature energy reservoirs, helping to reduce noise and power supply voltage fluctuations on the connected circuits. While in energy storage, it supplies rapid energy to the system, allowing it to reach the desired operating state quickly.

The working principle of the 298D107X06R3P2T capacitor is based on the standard capacitor principles of charge exchange. When a voltage is supplied, charges build up on the capacitor and an electric field develops between the plates. As charges accumulate, the voltage across the capacitor reaches its saturation point and the electric field dissipates.

In conclusion, the 298D107X06R3P2T capacitor belongs to the class of tantalum capacitors and it is mainly used for decoupling and energy storage. It is designed for both through-hole and surface mount applications. The working principle of the device is based on the standard capacitor principals of charge exchange and follows the behavior of all capacitors.
