Tantalum Capacitors

T494B156M010AT is a type of tantalum capacitor which is composed of a metallic tantalum anode lead, a manganese dioxide cathode lead, and an electrolyte of solid or gel. Although it is the smallest number of components among other types of capacitors, it still features a wide range of advantages such as high capacitance, low equivalent series resistance (ESR), and low leakage current.

Application Field

T494B156M010AT is a popular choice for electronic applications such as telecommunications and consumer electronic products, because it is small and relatively inexpensive. Tantalum capacitors are renowned for their high volumetric efficiency, making them a particularly attractive option for applications where space is limited. In addition, they are favored when low levels of leakage current and high capacitance are needed in order to limit current, smoothen pulsations, and provide coupling. Other fields where T494B156M010AT is used includes automotive, aerospace and military, and medical.

Working Principle

Tantalum capacitors use tantalum metal as the anode, manganese dioxide as the cathode, and electrolytic solution or gel for the dielectric. When voltage is applied, an electric field is present between the anode and cathode. The dielectric ensures that electrons reverberate between the two and increases the energy storing capacity. This essentially allows the capacitor to remain charged over time, even after the voltage is removed.In every capacitor, there is a certain amount of current leakage that occurs as ions travel through the dielectric. In some circumstances, for critical applications, such as in medical equipment or automotive safety systems, low leakage capacitors are necessary. If the leakage current is too high, the capacitor may not be reliable in the application.In addition, since the capacitors react to the changes in voltage, they are also used in filter circuits which provide voltage regulation, as well as in oscillators (used in timing circuits), and resonant circuits (used in radios, receivers, and other transmission devices).T494B156M010AT is an example of a high-performance capacitor and is especially suitable for consumer electronics and telecommunications. It has a higher voltage rating, a smaller size, and a faster charging time than standard tantalum capacitors. It also has a lower equivalent series resistance (ESR) for better current flow and lower inductance for better high-frequency performance.

Conclusion

T494B156M010AT tantalum capacitors are among the most reliable components for a variety of applications, from consumer electronics and telecommunications, to automotive and military. Although these capacitors have a low number of components, their advantages include high capacitance, low ESR, and low leakage current. This makes them a great choice for critical applications where voltage must remain constant, as well as for any application that requires small size and low cost.
