Tantalum Capacitors

Tantalum capacitors are highly valued for their reliability and cost-effectiveness across a broad range of applications within the electronics industry. From consumer and portable electronics to clean environments and defense applications, these devices are used to store and supply energy on-demand. The wide range of uses benefits from a variety of packages, voltage ratings, case sizes, capacitance ranges and more. One popular part of the tantalum capacitors family is the T95R226K050LSAS. The following sections will discuss the application field and working principle of this specific tantalum capacitor.

Application Field of T95R226K050LSAS

The application field of the T95R226K050LSAS encompasses a broad range of devices across different areas. Specifically for this part, it is a conductive polymer type that is designed and developed for the high temperature working environment, allowing its use in mobile phone batteries, electric cars, inverters, and other high temperature applications. This type of capacitor combines the features of an electrolytic capacitor with a tantalum oxide as the dielectric instead of aluminum oxide, providing the advantage of higher dielectric strength and lower leakage current.This type of device is also well suited for use in medical equipment and other cleanroom applications, due to its all-solid construction and range of polarized models. Because of its high reliability and robust construction, the T95R226K050LSAS can be easily incorporated into space-constrained designs. It is also well suited for use in automotive applications that may demand more performance and reliability than unipolar polymer capacitors, such as starter-motor or power-inverter solutions.

Working Principle of T95R226K050LSAS

The T95R226K050LSAS is a high-temperature type tantalum capacitor that works on the same principle as standard tantalum capacitors. The sensitive electrodes of this device are made up of a tantalum pentaoxide solid film, which is the tantalaum oxide (Ta2O5) form. The device is polarized, meaning that one side of the device is designed to be positive and the other side must be negative when in operation.When the device is energized, the positive voltage applied to the positive side of the device draws electrons from the negative side. These electrons are held by the oxide, which creates a layer of electrical charge responsible for storing energy. The oxide acts as a dielectric, allowing the charge to be stored and preventing it from flowing out.The stored electrical energy is discharged when the capacitor is de-energized, allowing the electrons to harmoniously travel from the negative side to the positive side. The dielectric prevents the opposite movement of current, maintaining the electrical charge and ultimately maintaining the capacitor\'s operational integrity.

Conclusion

The T95R226K050LSAS is a highly versatile and reliable solution for various applications in the electronics industry. Capable of handling high-temperatures and able to function in cleanroom and medical environments, this tantalum capacitor can offer unmatched performance when incorporated into space-constrained designs or demanding automotive applications. The working principle is the same as that of standard tantalum capacitors, relying on the oxide dielectric layer to maintain the stored electrical energy and keep the capacitor in operational integrity.
