T491B226M010ZTZV18 Application Field and Working PrincipleTantalum capacitors, or commonly known as tantalum electrolytic capacitors, are a type of capacitor that contains a tantalum metal as the anode material, with an oxide-based electrolyte serving as the cathode. They are highly reliable and offer excellent electrical characteristics, such as high capacitance, low leakage current, low dielectric absorption, and low ESR. As a result, they are commonly used across a wide range of applications, including in communication networks, automotive electronics, medical devices, consumer electronics, and industrial control systems.The T491B226M010ZTZV18 is a popular tantalum capacitor produced by a major manufacturer in Taiwan. It is a 22µF, 10V capacitor that is used in various electrical applications. It is constructed with a metallic case, with a ceramic disc and electrolytic material inside it. The T491B226M010ZTZV18 utilizes a two-layer anode construction, which increases its reliability and reduces failure rates.The T491B226M010ZTZV18’s working principle is based on the principle of capacitance. Capacitance is the measure of how much electric charge a device is capable of storing. A capacitor consists of two conducting plates separated by an insulating material. When a voltage is applied to the capacitor, an electric field forms between the two plates, causing electrons to be attracted to one plate and repelled from the other. This produces a capacitance value between the two plates, which is measured in Farads. The T491B226M010ZTZV18 works by creating an electric field within its two-layer anode construction. This electric field causes a charge to be stored in the capacitor and signals to be quickly transferred between the plates. The amount of stored charge is determined by the capacitor’s capacitance value, which in this case is 22µF. The 10V voltage rating of the T491B226M010ZTZV18 indicates its maximum operating voltage, which is the maximum voltage it can handle before its internal components are damaged.The T491B226M010ZTZV18 capacitor is typically used to filter out high frequency signals, which is known as bypassing or decoupling. It is also used in applications such as high voltage power supplies and sources, signal conditioning circuits, energy storage systems, motor controllers, and high voltage AC power transmission systems.In summary, the T491B226M010ZTZV18 is a highly reliable tantalum capacitor that is based on the principle of capacitance. It works by creating an electric field within its two-layer anode construction and can be used to filter out high frequency signals. The T491B226M010ZTZV18 is popularly used in various electrical applications, such as high voltage power supplies and sources, signal conditioning circuits, energy storage systems, motor controllers, and high voltage AC power transmission systems.
