Tantalum - Polymer Capacitors

T540D227M004BH86057280 capacitors are part of the family of tantalum-polymer capacitors (also known as Tan-Poly capacitors). These capacitors feature superior voltage characteristics, low temperature coefficient of capacitance (also known as “low ESR”), high reliability and low leakage current, making them suitable for high-end applications.

Application Field

Tan-Poly capacitors, such as the T540D227M004BH86057280 capacitors, are suitable for a wide range of applications, especially in the fields of electronic communication, computer science, and industrial control systems. In addition, they are often used in power supplies, circuit protection, and low noise applications. Thanks to their low temperature coefficient of capacitance and low leakage current, they are a popular choice for voltage-sensing circuits, as they are able to maintain stable voltage under high temperature modes.

Working Principle

T540D227M004BH86057280 capacitors use tantalum and polymer materials to construct an electrolytic capacitor. The construction is similar to a conventional electrolytic capacitor. It consists of two plates separated by an insulator, which is the electrolyte, and the plates are made of tantalum and polymer impregnated paper. The tantalum plate serves as the anode, while the polymer plate serves as the cathode. The electrolyte serves as the medium for the charge exchange between the electrodes.When a voltage is applied across the plates, a current flows between them, resulting in a charge accumulation on the plates. This charge accumulation increases the capacitance of the device. The capacitance of the T540D227M004BH86057280 capacitor is relatively high and this makes it suitable for a wide range of applications.Additionally, the tantalum-polymer material used in the construction of this device exhibits very low temperature coefficient of capacitance and very low leakage current. As a result, it is able to maintain stable voltage levels even when operating under high temperature conditions.

Conclusion

T540D227M004BH86057280 capacitors are part of the family of tantalum-polymer capacitors. They feature superior voltage characteristics, low temperature coefficient of capacitance, high reliability, and low leakage current which makes them suitable for high-end applications. These capacitors can be used in a wide range of applications, particularly in the fields of electronic communication, computer science, and industrial control systems. Due to their low temperature coefficient and low leakage current, they are also popular for voltage-sensing circuits.
