Tantalum Capacitors

The T4ZA474K020CRLB4900 is a tantalum capacitor that is used for many industrial applications. This type of capacitor is a good choice for many high-current, low-voltage applications. It is an efficient way to store energy in a small form factor. This article will discuss the application field and working principle of the T4ZA474K020CRLB4900.

Application

Tantalum capacitors are used in a variety of applications due to their high capacity, low leakage, and small size. This type of capacitor is particularly useful in high-current, low-voltage applications such as those found in computer motherboards, portable electronics, cell phones, and other components where space is a premium. It is also used in many large-scale electronic projects, such as military radar systems, as it can easily store a high amount of energy in a small package.

Working Principle

The T4ZA474K020CRLB4900 is a type of polymer tantalum capacitor. This type of capacitor consists of two layers of an electrolyte, an anode and a cathode. The anode is made of the tantalum material, while the electrolyte and cathode are usually made of manganese dioxide. The capacitance of this type of capacitor is determined by the combined surface area of the anode and cathode. These two layers are separated by thin-film insulation.

The capacitor is charged by applying a certain amount of voltage across the two layers. The voltage causes ions to flow from the anode to the cathode, resulting in a charge buildup. The anode is held at a negative potential and the cathode is held at a higher positive potential. This results in a charge buildup across the two layers that can then be used to store energy.

Conclusion

The T4ZA474K020CRLB4900 is a polymer tantalum capacitor that is used in various high-current, low-voltage applications. Its efficient design enables it to store large amounts of energy in a small package. This type of capacitor is well-suited for computer motherboards, portable devices, and other space-restricted components. Its working principle involves applying a voltage across the two layers, resulting in a charge buildup that can then be used to store energy.
