Introduction to Tantalum - Polymer Capacitors

Tantalum-polymer capacitors are a type of electrical component commonly used in the design and manufacture of a wide range of electronic devices. They are utilized due to their beneficial qualities such as low ESR, good capacitance stability and excellent temperature stability. As such, they are a vital part of ensuring circuit designs are reliable and perform efficiently over a range of ambient temperatures and operating conditions.

T540D476K020AH8605 – Overview

The T540D476K020AH8605 is a tantalum-polymer capacitor surface-mount, which is rated for a capacitance of 47 μF, a voltage of 6.3 VDC and an ESR of 0.056 Ohms at a temperature of up to 125 °C. These parameters are well suited for applications requiring extreme reliability, such as military applications and medical devices.

Application field

T540D476K020AH8605 is suitable for applications such as switching power supplies, automated test equipment, space-constrained applications, and any other applications that need high capacitance in a low footprint. It can also be used as an output filter or bulk storage capacitor within DC-DC converters and DC-AC inverters. In general, it is used for applications where low ESR and high ripple current is required.

Working Principle

Tantalum-polymer capacitors are constructed from stacks of tantalum-oxide dielectric layers and a polymer-based electrolyte which isolates the dielectric layers. During operation, a voltage is applied between the two plates of the capacitor, creating a polarized electric field. This electric field will store electrostatic energy and generates a dielectric loss depending on the thickness of the dielectric layers. The capacitance of tantalum-polymer capacitors is defined mainly by the number of dielectric layers and the applied voltage.

Conclusion

The T540D476K020AH8605 tantalum-polymer capacitor is suitable for a wide range of applications due to its small size, high capacitance, and low ESR. Specifically, it is ideal for space-constrained applications, medical devices, and military applications. It functions by creating an electric field between two plates of the capacitor, using an electrolyte to create a polarizing effect. This creates an electric field and stores electrostatic energy which supports excellent capacitance performance.
