Tantalum capacitors are an important type of electrolytic capacitor. They are highly reliable and are often used in military and telecommunication applications because of their low ESR (Equivalent Series Resistance) and high capacitance. The TRJC106K020RRJ is a popular tantalum capacitor that is commonly used for bypass and decoupling capacitors in a variety of circuits.

Physical Construction

Tantalum capacitors are constructed from a solid tantalum metal powder core with a coating of oxide on its surface. The core is either left un-electrolyzed or is electrolyzed with manganese dioxide. The capacitor is then sealed with a rubber or epoxy casing. The metal layers of the capacitor act as the anode and the oxide film acts as the dielectric. An outer metallized layer is typically applied for protection against environmental, mechanical and chemical stresses and is also used for heatsinking.

Working Principle

Tantalum capacitors operate on the principle of capacitance. When a voltage is applied to a capacitor, the electric field created between the two plates attracts the charge carriers, such as electrons, and stores energy. When the voltage is removed, the charge carriers repel each other and the energy is released. This charge and discharge cycle is the basis on which tantalum capacitors work.
