Tantalum – Polymer Capacitors

Tantalum capacitors provide high capacitance within small parameters, making it an excellent alternative to the standard ceramic and electrolytic capacitors. In comparison to other types of capacitors the most common advantage of the tantalum capacitor is that it has a high volumetric efficiency meaning it can hold a lot of charge in a smaller space than other types of products. In this article, we will look at the application field and working principle of TCNX476M025R0100 capacitor, an example of a high quality polymer tantalum capacitor.

Application Field

The TCNX476M025R0100 is a Ta-Polymer SMD capacitor made from a solid electrolyte anode with a manganese dioxide solid state electrolyte. It is especially suited for use in consumer electronics, mobile devices and other applications. Its high capacitance and tight voltage tolerance make it the perfect alternative in many situations. It offers a wide operating temperature range, making it suitable for use in even parts of the world with extreme temperature variations. The device is also particularly resistant to temperature and humidity, as well as temperature cycling. This makes it very reliable in demanding environments and ensures maximum product life.

Working Principle

A tantalum capacitor works similarly to a traditional capacitor, holding an electric charge in between its two electrodes to form an electric field. The anode is made from tantalum, which is an excellent conductor. This conductive material provides a robust and reliable electronic device. The cathode is made from manganese dioxide, which is a particular type of electrolyte that helps to boost the capacitance of the device. The capacitance of the device is determined by the size of its electrodes, the distance between the two and the type of electrolyte used. The higher the capacitance, the more charge the device can store. The device is electrically polarized and requires a positive voltage on the anode. The device then stores charge until it is discharged. It is also possible to use it to filter out frequencies and to reduce current variations in circuits.

Conclusion

The TCNX476M025R0100 is an excellent example of a high quality polymer tantalum capacitor due to its high volumetric efficiency, robust construction, and wide operating temperature range. It can be used in applications from consumer electronics to mobile devices. With its high capacitance and tight voltage tolerance, this capacitor is the perfect alternative for any application demanding reliability and long product life.
