Tantalum - Polymer Capacitors

TCJY227M004R0025 is a high-end prepared capacitor, which belongs to the category of tantalum-polymer capacitors. This type of capacitor has many advantages and is becoming increasingly popular in capacitive designs. This article will discuss the application field and working principle of TCJY227M004R0025.

Application Field

TCJY227M004R0025 mainly applies to high frequency, high temperature and medium frequency loads. Its high frequency performance is prominent and its temperature tolerance is superior. Its superior environmental characteristics make it suitable for various types of electronic equipment, particularly in the fields of communication, navigation systems, and radar systems. Moreover, its high performance level also makes it suitable for high frequency circuit design.

Moreover, it can also be used in low power applications. It has low leakage current, low dielectric absorption, excellent thermal stability and high capacitance stability, which makes it suitable for low power and low frequency applications. Additionally, its ultra-small packing size and good solderability make it suitable for diversified products.

Working Principle

The core of TCJY227M004R0025 is a tantalum anode and a polymer cathode. In the anode tantalum oxide film is chemically converted into a thin film on the surface, thus forming an oxide thickness of only a few nanometers (1 nanometer = 0.001 micrometer); the cathode is applied with organic materials synthesized by polymerization technology.

When the capacitor is operated, the anode is connected to one side of the power source and the cathode is connected to the other side of the power source which is ground. Electrons in the anode oxide film and the potential difference form a corresponding electric field between the oxide film and the cathode, while the electric field between the oxide film and the cathode is attenuated and adjusted by the material of the cathode, thus forming a capacitor.

With the combination of tantalum and polymer, the pitfalls of traditional electrolytic capacitors can be satisfactorily solved. Firstly, due to the shallow thickness of the oxide film, the loss of material from electrolyte corrosion during the operation has been avoided. Secondly, due to the provision of the polymer layer, with its excellent insulation and stability, the capacitance remains consistent when the temperature and frequency varies.

Conclusion

In conclusion, TCJY227M004R0025 is a type of tantalum-polymer capacitor which is suitable for high temperature and medium frequency loads. Its high frequency performance and temperature tolerance are both superior, and its small size and good solderability make it suitable for low power and low frequency applications. The working principle of TCJY227M004R0025 involves the combination of a tantalum anode and a polymer cathode to form a capacitor. Through its combination with tantalum and polymer, it is possible to solve the problems of traditional electrolytic capacitors.
