Tantalum Capacitors

Tantalum capacitors are among the most widely used type of electronic component in consumer goods, medical, industrial and military products. The TPSE108K004R0040 is a type of surface mounted tantalum capacitor manufactured by AVX Corporation, designed for applications requiring high capacitance and low ESR characteristics. In this article, we look at the application fields and working principles of this component.

Application Fields

The TPSE108K004R0040 tantalum capacitor is a surface mount component that is typically used in high-density consumer and industrial applications, such as television sets, telephones, computers, cellular phones, video game consoles, aircraft and aerospace systems, and military equipment. Its small size and high voltage capability make it well suited for these types of applications.

The TPSE108K004R0040 is also gaining popularity in medical applications due to its high capacitance, low ESR and high voltage ratings. It is ideal for use in pacemakers, disposable medical diagnostic test kits and other medical devices. It is also used for medical device power bus structures, high-speed data converters, LED and LCD displays, power conditioning circuits and power factor correction.

Working Principle

The TPSE108K004R0040 is constructed from two electrically conductive layers of tantalum metal separated by a dielectric layer. It works on the principle of dielectric absorption, where an electric charge is stored in the dielectric material when an electric field is applied between the electrodes. This stored energy is then released when the electric field is removed.

The amount of charge stored in the dielectric is determined by the capacitance rating of the device, which is measured in Farads. The tantulum capacitor also has a low ESR (equivalent series resistance) rating, which is typically lower than 5 ohms. This low resistance to current flow allows it to quickly charge and discharge, making it well suited for high- speed digital applications.

Conclusion

The TPSE108K004R0040 is a surface mounted tantalum capacitor manufactured by AVX Corporation. It is designed for applications requiring high capacitance, low ESR and high voltage capability. The capacitor is widely used in consumer and industrial applications such as television sets, cellular phones and medical devices. The capacitor works based on the principle of dielectric absorption, where an electric charge is stored in the dielectric material.
