The working principle of the T491C476K020AT is based on the electrostatic field generated between two conductive plates. The two plates are separated by a dielectric material, typically a tantalum pentoxide film, and are held tightly together with an electrolytic solution. When a voltage is applied, the surface of the plates become polarised, forming an electric field around them. This creates an electrostatic field in the dielectric that stores the energy and releases it when the voltage is removed.

The T491C476K020AT has excellent temperature stability and is capable of withstanding high temperatures up to 125°C without compromising its performance. It is also highly resistant to electromagnetic interference and vibration, making it suitable for use in extreme conditions. Additionally, the T491C476K020AT is a relatively low profile capacitor, making it suitable for use in space-constrained applications.

The T491C476K020AT is an excellent choice for high performance, high temperature applications. It offers superior reliability and performance, as well as outstanding temperature stability. Its low profile and high resistance to EMI and vibration make it a valuable tool in many demanding environments. It is ideal for use in automotive, power management, audio, communications and industrial applications where reliability and performance are paramount.
