Tantalum - Polymer Capacitors have become increasingly popular in the electronics industry due to their advantages such as volumetric efficiency, low ESR and high capacitance. The T550B687M008AT4250 is a type of tantalum-polymer capacitor commonly used in a variety of electronic applications.

General Overview

The T550B687M008AT4250 has a rated voltage of 10 Volts, a capacitance of 8.7uF, and an ESR (Equivilent Series Resistance) of 0.4 ohms. It is available in package sizes of 4.2mm x 5.0mm x 5.0mm, and a wide variety of terminal types. It has a temperature range of -55C to +125C.

Application Field

The T550B687M008AT4250 tantalum-polymer capacitors are most commonly used in high frequency and RF (Radio Frequency) applications. It is particularly well-suited for use in power conditioning and storage, filtering circuits, and as high-speed clock buffers. It is also suitable for blending with other types of capacitors to reduce ESR in high-noise environments.

Working Principle

The T550B687M008AT4250 is a tantalum-polymer capacitor, which means it is made from a combination of tantalum and plastic polymer material. The combination of these materials gives the capacitor its capacitance, voltage rating, and stable characteristics.

Tantalum-polymer capacitors consist of three main components; the anode, the dielectric layer, and the cathode. The anode and cathode are both composed of tantalum metal, while the dielectric layer is composed of an inert organic polymer material. When charge is applied to the capacitor, it creates a electrostatic field, which forms an insulating barrier between the anode and the cathode. This insulator then stores the electrical charge, allowing the capacitor to maintain its capacitance and voltage rating.

Conclusion

In conclusion, the T550B687M008AT4250 tantalum-polymer capacitor is an excellent choice for applications requiring high frequency and RF performance. Its low ESR and high capacity make it an ideal choice for power conditioning and storage, filtering circuits, clock buffering, and high-noise environments. The combination of tantalum and polymer materials creates a robust capacitor capable of handling extreme temperatures and a wide range of conditions.
