In addition, it has a long shelf life and a high resistance to corrosion.

Due to its small size, the T491B475M016ZT is primarily used in applications that require a very small form factor. Moreover, it can operate at very high frequencies and is often used in high-frequency circuits. Its low profile allows for easy insertion into densely packed and shielded circuitry.

Working Principle of the T491B475M016ZT

T491B475M016ZT uses a solid electrolyte capacitor, which means that it doesn\'t require a wet electrolyte for its operation. It operates as a capacitor with two metal plates that are separated by an insulating material that is called the dielectric. The dielectric material between the two metal plates is MnO2. The capacitor’s terminals are the two plates, one of which is attached to a metal end cap.

An electric field is created inside the capacitor when an external voltage is applied. This electric field creates a surface layer of electrons that sets up the current flow by establishing an electric circuit. Since the capacitor’s terminals are electrically connected, it is now possible to conduct an alternating current, with one terminal being positive and the other negative. This alternating current is what provides the capacitance of the capacitor.

In addition, when the external voltage is changed, the electric field around the capacitor is also changed, resulting in a change in capacitance. This ability to change the capacitance makes the capacitor ideal for use in various electronic applications, such as frequency control, signal filtering, and memory storage.

Applications of the T491B475M016ZT

Due to its small size and low ESR, the T491B475M016ZT is often used in high-frequency applications. It is typically used in applications requiring very high-speed data transmission, such as DSL, Wi-Fi and Bluetooth. It is also used in audio and video applications, as it has excellent temperature stability and noise suppression. It is also used in memory storage applications, as it is capable of storing energy even in the presence of fluctuations in voltage, thereby avoiding data loss.

The T491B475M016ZT is a reliable and well-performing capacitor that is ideal for use in high-frequency and high-density electronic equipment. Its small size and low ESR make it suitable for many different applications and is a popular choice for many engineers thanks to its reliability and long shelf life.
