T491A225M020ZT capacitors are polymer tantalum capacitors. They are used primarily in communication devices, but can also be used in other electronic circuits such as automotive, industrial, and medical applications. Tantalum capacitors are named after their main component, Tantalum, which has excellent electrical and thermal properties.Although they are very small, they can store energy and thus are heavily used in many electronic circuit designs.

How Do Tantalum Capacitors Work?

A tantalum capacitor is composed of an anode (positive electrode), a cathode (negative electrode), and an electrolyte (dielectric). The anode is typically made from tantalum, while the cathode is either manganese dioxide (MnO2) or metal oxide. The capacitor works by storing electrical charge between two metal plates separated by an inert material or dielectric. When voltage is applied to the plates, an electric field is established in the dielectric, and it stores energy.

The capacitor charges up when it is connected to the power source. As it charges, electrons flow from the anode into the cathode, forming a build-up of charge on the anode side. This creates an electric field in the dielectric that holds the charge until the capacitor is discharged. When it is discharged, the electrons return to the anode and the capacitor is ready to be recharged.
