Tantalum Capacitors

Tantalum capacitors are parts with a high-capacitance, low-ESL, long-life and good stability. They are widely used in different scenarios, including automotive, communication, industry and consumer electronics. In this article, we will take the 293D684X0025B2TE3 capacitor as an example to show its application field and working principle.

The 293D684X0025B2TE3 tantalum capacitor is a surface-mountable capacitor with a voltage rating of 25 Volts and an upper temperature rating of 125°C. It features a high capacitance-to-volume and a high-temperature range performance. With its reliable performance and low ESL, it is mainly used in circuits with high frequency and current power, such as motor control, power supply, and amplifiers. Furthermore, the small size of the capacitor makes it suitable for small, space-constrained projects.

The working principle of the 293D684X0025B2TE3 tantalum capacitor is based on a dielectric interface between two metal surfaces. The metal surfaces are usually formed from tantalum as it has a high electrical resistivity. When a voltage is applied to the tantalum layer, an electric current is generated which causes the electrical charges to accumulate at the dielectric interface, forming an electric field which stores energy. These electric fields act as energy sources and store energy to the capacitor.

In conclusion, the 293D684X0025B2TE3 is a reliable, low-ESL tantalum capacitor suitable for a wide range of applications. It features a high-capacitance and a high-temperature range performance that makes it ideal for circuit applications with high frequency and current power, such as motor control, power supply, and amplifiers. Moreover, its small size makes it suitable for small, space-constrained projects. Its working principle relies on the combination of an electric current generated by the tantalum metal surface and an electric field formed by the electric charges at the dielectric interface to charge and store energy.
