Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, offer a range of advantages to their users. They provide excellent reliability and stability, are small and lightweight, and are able to withstand high temperatures. The TAP476K020HSB is a tantalum capacitor with a solid electrolyte for use as an Application Specific Industrial Capacitor (ASIC). In this article, we discuss the application field and working principle of the TAP476K020HSB.

Application Field

The TAP476K020HSB is designed for use in high reliability industrial control applications. It is primarily used to filter and store energy in components such as power supplies, inverters, and rectifiers. It also provides a buffering function to help regulate voltage levels. Its small size and low thermal resistance make it well suited to embedded applications where space and energy efficiency is of paramount importance.

Working Principle

Tantalum capacitors are essentially two metal plates separated by an insulating dielectric material. When an electric field is applied, an opposite electrostatic field is produced which attracts the mobile electrons and ions towards the oppositely charged plate. As the charge builds up on the plates, the capacitance increases, storing energy between them.

For the TAP476K020HSB, two tantalum anodes are separated by a solid electrolyte. This electrolyte helps regulate the movement of the ions between the anodes. As charge builds up, it provides a buffering effect which helps maintain voltage levels between the two plates. The capacitance of this unit is rated at 4.76 μF with a voltage rating of 20V.

Conclusion

The TAP476K020HSB is a high-reliability industrial capacitor which is well suited for embedded applications where high temperature stability, small size, and low thermal resistance are necessary. It uses two tantalum anodes separated by a solid electrolyte, which helps to store and regulate electrical charges. The capacitance value is 4.76 μF while the voltage rating is 20V.
