It can be used to provide filtering for oscillators and pulse waveforms, and its low equivalent series resistance makes it suitable for use in high-speed circuits.

Working Principle

The TAJA684K020HNJ is a surface mount tantalum capacitor, which uses a solid, thin tantalum wire as the capacitor’s electrodes. The wires are encased in a conductive layer of tantalum pentoxide, which acts as the dielectric material. When the capacitor is connected to an electric field, the tantalum wire will draw the electric charge and create an electric field within the capacitor. This electric field stores the energy as an electric field within the oxide layer. When a current is applied to the capacitor, the charge stored in the oxide layer will discharge, resulting in a current flow. The capacitor can then be recharged by passing a current in the opposite direction, or by disconnecting the capacitor and allowing the charge to re-establish itself.

Conclusion

The TAJA684K020HNJ is a surface mount tantalum capacitor from KEMET that provides reliable performance in a wide range of applications. It has a low ESR (Equivalent Series Resistance) of 8mΩ and a high capacitance of 6.8μF, making it suitable for use in high-performance electronic circuits.
