Tantalum - Polymer Capacitors

Introduction

Tantalum - Polymer Capacitors, or TPCs, are a class of electrolytic capacitors. They combine the advantages of traditional tantalum capacitors with the superior endurance of tantalum polymer capacitors, making them an ideal choice for many high-performance applications. The T540D336K0AT8505 is a specific TPC model manufactured by Kemet. Its features and applications make it an ideal choice for many users.

Features

The T540D336K0AT8505 offers a long list of features that make it stand out from other TPC models. It has a working voltage range of 16V to 50V, depending on the application, with a rated ripple current of 25mA. Its maximum capacitance is 0.33F, with a maximum ESR of 0.033 ohms. It also offers a capacitance tolerance of +/-10%, a surge current rating of 250mA, and a maximum aging rate of 5%.

Applications

The T540D336K0AT8505 is an ideal choice for a wide range of applications due to its superior performance characteristics. It is suited for high-power audio and video systems, medical diagnostic equipment, and precision instrumentation. Additionally, it can be used in automotive applications such as power steering control units and fuel injection systems. It is also ideal for battery-backed memory protection, power supply regulation, and filtering circuits.

Working Principle

Like all capacitors, the T540D336K0AT8505 works by storing energy in an electric field. This occurs when two inert metal plates are placed in a dielectric material, such as a plastic or ceramic coating. When an electric current is applied to the capacitor, electrons move between the two plates, creating a charge that builds up in the electric field. This stored energy is then released as the capacitor is discharged.In the case of the T540D336K0AT8505, the capacitor is made of a tantalum chip surrounded by a solid polymer dielectric material. This design ensures higher reliability and longer life than many other types of capacitors, due to the polymer trapping charges in the electric field and the ability of the tantalum chips to better withstand temperature variations and vibrations.

Advantages of Tantalum - Polymer Capacitors

The T540D336K0AT8505 offers many advantages to designers, including high reliability, low ESR, long life, and a wide range of applications. Its construction from tantalum and polymer materials help to ensure its longer life and excellent performance. It also requires minimal maintenance, making it ideal for long-term use. Finally, its design ensures increased safety and reliability compared to other types of capacitors.

Conclusion

The T540D336K0AT8505 is an excellent choice for designers and engineers looking for high-performance capacitors. Its features and construction make it well suited for a wide range of applications, including automotive, audio, video, medical, and instrumentation. Additionally, its long life, high reliability, and low ESR make it an extremely reliable and safe choice for many users.
