Tantalum - Polymer Capacitors

Tantalum-polymer capacitors are, essentially, a combination of the features of the two different types of capacitors – good electrical characteristics of tantalum capacitors and low cost and low profile feature of polymer capacitors. The T540D337K004BH8605 capacitor is one of these tantalum-polymer capacitors and belongs to the agreement of KEMET capacitors.

Application Field of T540D337K004BH8605

The T540D337K004BH8605 capacitor, along with having many other applications, is mostly used in the commercial and military electronics of low profile applications. Its very small dimensions and low parasitic inductance make it ideal for energy storage and pulse power applications. Its lead-free terminations also make it a perfect choice for many of the safety and environmental requirements that are needed in some of these applications.

T540D337K004BH8605 capacitor is often used in the fields of telecommunication, medical electronics, automotive electronics, aerospace, industrial electronics and maritime electronics, instrumentation and various power supply options in the wider range. Because of its low ESR and C0G temperature characteristic, the T540D337K004BH8605 capacitor often finds use in high temperature applications where no other capacitor can be used.

Working Principle of T540D337K004BH8605

The T540D337K004BH8605 capacitor works on the concept of electrical energy storage and uses Faraday’s law of induction to function in its most effective way. It utilizes the dielectric material between its electrodes to store the electrical energy, where the electrical charge is stored on the inner surface of the electrodes. This electrical energy is then released when the opposite charges appear at the terminals of the capacitor.

The dielectric material between the electrodes of the capacitor prevents this energy from being discharged at an unsafe or undesirable rate. This process of energy storage-and-release happens in a fraction of a nano-seconds and this makes the capacitor to perform its primary function such as filtering, coupling, storing, buffer and conditioning of the electrical signals in the most efficient manner.

The capacitance of the capacitor is determined by the area of the two electrodes and the distance between them. In order to reduce the capacitance of the capacitor, the distance between the electrodes is increased, and for increasing the capacitance, the distance between the electrodes is reduced. This is an important parameter in the designing of any electronic system and is determined according to the application that is intended for use.

Conclusion

The T540D337K004BH8605 capacitor is a tantalum-polymer capacitor that is used for many applications related to telecommunication, medical electronics, automotive electronics, aerospace, industrial electronics and maritime electronics, instrumentation and various power supplies. The working principle of this capacitor is based on Faraday’s law of induction using the dielectric material between two electrodes. The capacitance of the capacitor is determined by the area of the two electrodes and the distance between them. This capacitor is especially known for its usage in low profile applications and its lead-free terminations make it an ideal choice for many of the safety and environmental requirements needed in these applications.
