What is a Tantalum Capacitor?

A Tantalum capacitor, also referred to as a Ta-Cap is a type of passive component which is used in many areas of electronics. It is a non-polarized device with a higher specific electrical resistance than other types of capacitor, meaning it is capable of storing a greater amount of energy. Tantalum capacitors are used in a variety of applications, primarily as an energy source, such as in audio and computer applications. The T491D226K020AT4659 tantalum capacitor is a type of tantalum capacitor with a size of 4.7 x 6.3mm, with a rated voltage of 20 Volts.

T491D226K020AT4659 Application Fields

The T491D226K020AT4659 tantalum capacitor is primarily used in low-frequency, low-power applications, such as in clocks, sensors and switch-mode power-supply circuits. This type of capacitor is also popular in audio and data-processing circuits, such as for audio filters, signal conditioning and noise reduction.T491D226K020AT4659 can also be used in power management, where it works with other components to help regulate power and voltage. In high-voltage applications, it can help protect components from voltage surges, and in low-voltage signals, it can help reinforce weak signals by storing energy and releasing it in pulses.

T491D226K020AT4659 Working Principle

Like all capacitors, the T491D226K020AT4659 works by storing electrical energy on two flat surfaces, separated by a non-conductive dielectric. When a voltage is applied to the terminals, the electric charge accumulates on the surfaces, creating an electric field between them. This electric field generates an electrostatic capacitance, and thus it is able to store energy between the two plates. When this stored energy is released, it generates a current in the circuit which can be used for any desired purpose. T491D226K020AT4659 is a non-polarized device, meaning that the amount of energy stored on both surfaces is equal, and the voltage between them is constant. As such, it is able to provide a steady and reliable supply of energy over a long period of time.

Conclusion

T491D226K020AT4659 is a type of non-polarized tantalum capacitor which is primarily used in low-frequency, low-power applications. It has a higher specific electrical resistance than other types of capacitor, meaning it is capable of storing and releasing energy more efficiently. As such, it is commonly used in audio and data-processing circuits, as well as power management, surge protection and signal reinforcement. The T491D226K020AT4659 works by creating an electric field between two flat surfaces, thereby creating an electrostatic capacitance and enabling it to store energy as electrical charges. When this stored energy is released, it generates a current in the circuit which can be used for any desired purpose.
