Tantalum Capacitors

Tantalum capacitors are components that store and release electrical energy. This type of capacitor is made from tantalum, an element that has a high electrical resistance or capacitance. Tantalum capacitors have several applications across diverse fields, and the one under consideration here is the 893D476X06R3D2TE3. This paper will discuss its application field and working principle.

Application Field

The 893D476X06R3D2TE3 tantalum capacitor is most commonly used in audio and communication devices such as radios, TVs, and amplifiers. It is also preferred in automotive applications like power supplies, alternators, and engines. These capacitors can also be used in power tools, electric vehicles, and in medical equipment.

The 893D476X06R3D2TE3 tantalum capacitor is preferred in these applications because of its ability to deliver high levels of pulse current in a small package. It has a very low equivalent series resistance (ESR) and can be used in high-speed switching and linear applications due to its low dissipation factor.

Working Principle

The 893D476X06R3D2TE3 tantalum capacitor is an electrolytic type capacitor with an anode made from a solid tantalum rod and a cathode made from its oxide film. The anode is positive while the cathode is negative. The capacitor consists of three main parts including the electrolyte, cathode, and anode. The assembly is then connected to an electrolyte. When an external voltage is applied, ions from the electrolyte are attracted to the anode of the capacitor and form an electric double layer.

This electric double layer comprises a positively charged layer of cations which adheres to the anode while the negatively charged layer of anions adheres to the electrolyte. The ions provide a high capacitance and allow the electric current to flow through the capacitor. The capacitor’s capacitance value is determined by the size of the electrode area and the amount of electrolyte used.

In the 893D476X06R3D2TE3 tantalum capacitor, the anode and cathode layers of the electric double layer form a thin layer of tantalum pentoxide. The capacitor is very stable with a high tolerance and is also capable of delivering high amounts of pulses. The total capacitance value is marked on the capacitor and is typically in the order of picofarads (pF).

Conclusion

The 893D476X06R3D2TE3 tantalum capacitor is a component designed for storing and releasing electrical energy. It has a wide range of applications in audio and communication devices, automotive applications, and medical equipment. Its working principle involves the formation of an electric double layer made up of cations and anions, which allow electric current to flow through the capacitor. It is a very stable device with a high tolerance, and it is capable of delivering high amounts of pulses.
