Tantalum Capacitors

Tantalum capacitors are specialized capacitors consisting of a tantalum material as the electrode with an electrolyte. They are similar to aluminum electrolytic capacitors in terms of electrical characteristics and are used in situations requiring higher stability, higher working voltage and lower leakage current.

The TLJA227M004R1100 Series is a surface mount, high temperature, applied field aluminum polymer capacitor. It is an ideal solution for a variety of applications. This series provides good stability and low ESR.

Application field

The TLJA227M004R1100 series are widely used in many industries and applications, such as in the automotive industry for electronic components in EMI/RFI filtering, power supply, voltage regulators, DC-DC converters, LED lighting, industrial control, switching power supply, aviation, medical electronics, telecommunication base station, energy storage fields, etc.

Working Principle

A tantalum capacitor consists of an anode, an electrolytic material (solid or liquid), and a cathode. In operation, the material between the anode and the cathode will resist the flow of electrons between them, causing a capacitance. The amount of capacitance will depend on the size and shape of the capacitor, as well as on the dielectric material used.

Tantalum capacitors typically have a higher ESR (equivalent series resistance) than aluminum electrolytic capacitors. This is largely due to their lower self-inductance, which results in a higher current ripple for a given frequency. But the benefits in terms of size, weight and stability offset this disadvantage.

Due to its low ESR, the TLJA227M004R1100 series provide good stability over time and high current handling capability. They are also capable of operating at high temperature, up to 300°C. This makes them ideal for applications where a high degree of accuracy and stability is required.

Conclusion

The TLJA227M004R1100 series is a surface mount, high temperature, applied field aluminum polymer capacitor. It is an ideal solution for a variety of applications, such as automotive, industrial, aviation, medical electronics and energy storage fields. This series provides good stability and low ESR and is capable of operating at high temperature, up to 300°C.
