Tantalum-polymer capacitors are conductive constructional elements with high performance properties. Their increase in popularity in recent times has been driven by their ability to provide reliable, small form factor solutions for the electronics industry. The T540D227K004CH85057280 is one such device, designed for applications that require higher capacitance, lower leakage current and lower equivalent series resistance (ESR), allowing for higher voltages and faster charging times. In this article, we shall examine the application field and working principle of the T540D227K004CH85057280.

Application Field

The T540D227K004CH85057280 is primarily designed for use in applications where high power density is required. Such applications include electric vehicles, medical devices, industrial automation, power conversion, and state-of-the-art military systems.

The device is ideal for high-temperature and harsh environment applications, such as aviation systems, where reliable and lightweight solutions are necessary. Its impressive form factor also renders it suitable for mobile phone circuitry, where space is at a premium.

Working Principle

Tantalum-polymer capacitors are constructed according to a unique hybrid technology. This technology involves a layering of semiconductor dielectric layer, along with an embedded tantalum wire mesh, which are separated by a polymer layer.

This form of capacitor consists of two overlapping films that are separated by a polymer insulation layer. One film consists of a semiconductor material, while the other film is made of conductive material, commonly tantalum. When a potential difference is applied on the capacitor, an electric field is formed due to the semiconductor and conductive films, which results in an electromotive force being created. This electric field causes ions to move from one side of the layer to the other, which creates a charge. This electric field is then used to generate a voltage across the device.

The T540D227K004CH85057280 consists of a thickness of 0.40 mm with a maximum working voltage of 6.3V. It has a capacitance of 2200uF, a leakage current of 0.02uA and an ESR of 0.87mohm. All of these features combine to make it perfect for use in applications requiring high power density.

Conclusion

In conclusion, the T540D227K004CH85057280 is a reliable device, designed for applications that require higher capacitance, lower leakage current and lower equivalent series resistance (ESR). It is mainly used in applications where high power density is required and is exceptionally suitable for mobile phone circuitry, electric vehicles, and medical devices. Its working principle involves two overlapping films that are separated by a polymer insulation layer, one of which is made of semiconductor material, and the other of conductive material. This creates an electric field between the two, which is used to generate a voltage across the device.
