T491X107K020AT7622 Application Field and Working Principle

T491X107K020AT7622 tantalum capacitors are a type of electrolytic capacitor with an electrolyte of tantalum pentoxide that exhibits excellent stability and reliability. It is mainly used in high-temperature, high-power and high-frequency circuits where a stable, reliable performance is critical. The capacitor consists of two types of materials - a dielectric (electrolytic) material such as tantalum and a conductive material such as aluminum or silver. The two materials are separated by a dielectric layer. When an external voltage is applied to the capacitor, it stores electric energy which is released when the external voltage goes away.

The T491X107K020AT7622 tantalum capacitor is characterized by its small size, low dielectric absorption, long service life, excellent frequency characteristics, low leakage current, and good temperature resistance (from -55°C to +125°C). It is suitable for various circuit applications, such as power supply bypass circuits, switching regulator circuits, and high-powered radios. It is also widely used in aerospace and military equipment.

The working principle of the T491X107K020AT7622 capacitor is based on the physical phenomenon of electrical capacitance. When a voltage is applied across the capacitor, it behaves like a pair of metal plates, where one plate carries a positive charge and the other carries a negative charge, thereby creating an electric field between the two plates. This electric field stores the energy in the form of electrical charge, which is then released as current when the voltage is removed. The capacitor thus behaves like a battery, storing and generating electrical energy depending on the applied voltage.

The capacitor’s capacity is determined by the size of its capacitance, which is mostly determined by the capacitor’s dielectric material and its physical size. The size of the capacitor is also a critical factor in determining its ability to store and supply energy, with larger capacitors having a greater capacity for storing charge.

The T491X107K020AT7622 capacitor is a great choice for high-temperature, high-power and high-frequency uses due to its excellent stability and reliability. Its small size, along with its low dielectric absorption, long service life, excellent frequency characteristics, low leakage current, and good temperature resistance make it an ideal choice for a wide variety of electronic applications.
