Tantalum Capacitors

T495X476K020ASE150, also known as tantalum capacitors, are widely used in a variety of electronic applications, ranging from small cell phones to large computer systems. This capacitors have a number of advantages over other capacitor types, making them well suited for many different applications.

Application Fields

Tantalum capacitors are most commonly used in applications requiring large amounts of power. Examples include power supplies, drive circuits, motor controllers, and audio amplifiers. They are also used in industrial applications, as they are able to handle high current levels when subjected to voltages higher than the maximum operating voltage of the device.

Tantalum capacitors are also frequently used in automotive and aerospace applications. They are capable of providing the high-voltage and current levels necessary for these industries. They are also resistant to shock, vibration, and moisture, making them well-suited for these types of applications.

Tantalum capacitors can also be used in timing circuits, such as those used to control the speed of motors or machines. They are also sometimes used in switching circuits, as they are able to store large amounts of energy and discharge it quickly, making them ideal for this application.

Working Principle

Tantalum capacitors work on the same principle as any other capacitor -- they store energy in an electrical field created by the two plates, one positive and one negative. The plates are separated by a dielectric material, such as tantalum oxide, which increases the capacitance of the capacitor. As the voltage increases, the electrical field between the two plates grows stronger, resulting in more energy being stored in the capacitor.

The current that can be provided or taken from a tantalum capacitor is limited by its size and the material used for its construction. For example, a larger tantalum capacitor will be able to provide higher current levels than a smaller capacitor of the same type. Additionally, the dielectric material used will affect the maximum voltage that the capacitor can handle. For example, tantulum oxide can handle voltages of up to 2000 volts, while other materials, such as aluminum oxide, can handle voltages of up to 16 volts.
