Tantalum Capacitors

Tantalum capacitors (also known as Ta-cap) are widely used in electronic circuit boards due to their stability, reliability, and performance. T491D476K016AT4280 is a type of tantalum capacitors, which is designed to meet specific requirements. This article will discuss its application field and working principle.

Application Field

T491D476K016AT4280 tantalum capacitors are mainly used in communication network and power electronics. It is a great choice for applications that require wetted surface area, high capacitance, and low voltage. It is also suitable for such subject fields as telecommunication, aerospace and automotive industries. In addition, it can be used in power supplies, filters, mobile devices, signal control and etc.

Working Principle

The working principle of T491D476K016AT4280 relies on the same electrical principles as other capacitors. Generally, it works on the principle of electrostatic capacitance, which means the capacitor stores electrical energy in an electrical field set up between two conductive plates separated by a nonconductive dielectric material. The dielectric is usually tantalum, but other materials are available. When a voltage is applied to the capacitors, the charged particles within the dielectric cause the plates to become oppositely charges, creating an electrical field. Because of this field and the material between the plates, electrons are able to flow between the plates, allowing the capacitor to store energy.

Conclusion

T491D476K016AT4280 is a type of tantalum capacitors, which is mainly used in applications in communication network, power electronics and other related fields. It works on electrostatic capacitance principles and relies on the setup between two conductive plates separated by a nonconductive dielectric material. Ultimately, it is an effective solution for achieving a stable, reliable, and performant circuit board.
