Tantalum Capacitors

A tantalum capacitor is an electrolytic capacitor, a component of electronic circuits, that consists of a pellet of tantalum on which a very thin layer of oxide is formed. The oxide layer serves as a dielectric, which stores electric charge. On each side of the pellet is an electrode, supplied with electric current, to which a positive and/or negative voltage can be applied. The electric fields generated by the electrodes interact with electric charges stored in the oxide layer. This way the capacitance of the capacitor is enforced.

They are also used in voltage regulator modules and in communications systems, including base-stations, outdoor antennas, and radio transceiver units.

Working Principle

The T491A475K006AT7280 capacitor uses the same basic principles as other tantalum capacitors, namely the creation of a charge-storing oxide layer. The positive and negative pole of the capacitor are connected to the respective dots indicated on the casing. When voltage is applied to the capacitor\'s electrodes, the electric field generated causes an electric charge to be stored in the oxide layer, building up a charge differential between the two poles. This charge difference can be increased or decreased by altering the voltage applied to the electrodes. When current needs to be supplied, the capacitor discharges its stored charge, allowing an electric current to flow between the two poles.

Conclusion

The T491A475K006AT7280 is a high-capacity, low-void-type tantalum capacitor designed for use in applications requiring reliable and accurate charge storage. It is used in a variety of portable communication and medical devices, as well as in voltage regulator modules and communications systems. The capacitor functions by creating a charge-storing oxide layer between its positive and negative pole, which allows an electric current to flow when the stored charge is discharged.
