Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are polarized capacitors which use tantalum as an electrode. They are used in a variety of applications, including portable electronics, mobile phones, air conditioning units, and automobile systems. Tantalum capacitors are composed of two electrodes, an anode and a cathode, and have an electrolyte, which can be a liquid or solid. They are usually encased in a plastic void.

293D474X0035A2TE3 Working Principle

The mechanisms of tantalum capacitors are similar to those of other capacitors, only their electronic structure is different. This capacitor has two electrodes: the anode and the cathode. As the anode is charged, it attracts electrons to the surface, forming a layer of positively charged ions. At the same time, the cathode attracts electron negative charge. This creates an electronic field between the two electrodes, which is known as the dielectric layer.

This dielectric layer acts as an insulator, meaning that it disallows the electrons from travelling between the anode and the cathode. Further charging of the capacitor increases the dielectric layer, thus increasing the capacitance. When the charges stored in the dielectric layer reach equilibrium, the capacitor will stop charging. Discharging the capacitor will cause the dielectric layer to reduce, thus reducing the capacitance. In this way, the process of charging and discharging the capacitor determines its capacitance.

The 293D474X0035A2TE3 tantalum capacitor offers enhanced levels of performance and reliability. It is a robust device which is well-suited for applications requiring high temperatures and low profiles. Its capacitance range of 3.2-4700µF make it suitable for a variety of applications, making it a popular choice among electronic engineers.
