Tantalum capacitors are specialized capacitors that offer the combination of high capacitance per unit volume, high reliability and low equivalent series resistance, making them useful in a wide variety of applications. The TAJA475K016UNJ series of tantalum capacitors is designed to offer even higher levels of performance while still providing great levels of reliability. This article will look at the application fields and working principles of the TAJA475K016UNJ series, as well as its features.

Application fields

The TAJA475K016UNJ series of tantalum capacitors is an advanced option for applications which require higher levels of reliability and performance. These capacitors can be used in a wide range of industrial, automotive and aerospace applications. The capacitors are suitable for general-purpose military and commercial use, and are suitable for operation in temperatures between -55°C and 105°C. They are particularly useful in high-temperature applications, as they exhibit a high thermal and electrical stability. This makes them ideal for use in applications such as high-side current sensing in automotive power applications.

Working Principle

The TAJA475K016UNJ series of capacitors are multi-layer capacitors which use an anode made from a solid electrolyte such as tantalum pentoxide. This anode is coated with an electrically conductive material, such as silver, which forms an ionic bridge between the anode and the cathode. Since the anode is made from a non-conductive material, the current must flow through the bridge in order to reach the anode and for charge to be transferred.

The working principle of the TAJA475K016UNJ series is based on the concept of double-layer capacitance. In this system, the anode and cathode are separated by a dielectric layer, and when a voltage is applied to the capacitor, charge accumulates on both the anode and cathode. This charge is then released when the voltage is removed, and the capacitor is said to have a double-layer capacitance.

Features

The TAJA475K016UNJ series of capacitors offers several features which make them suitable for high-performance applications. These features include a rated voltage of 16V, a capacitance range of 47 to 470μF, and a tolerance of ±10%. The capacitors are also RoHS compliant, and feature an enhanced protective coating for reliable operation in harsh environments. In addition, the capacitors are also suitable for automotive applications, and offer very low internal resistance even at high temperatures.

Overall, the TAJA475K016UNJ series of tantalum capacitors offers excellent levels of performance and reliability for a wide range of applications. The capacitors offer a very high capacitance-to-volume ratio, making them ideal for high-density applications. The capacitors are also designed to offer superior performance in high-temperature applications, and are RoHS compliant.

Conclusion

The TAJA475K016UNJ series of tantalum capacitors is an advanced option for applications which require higher levels of reliability and performance. The capacitors offer a very high capacitance-to-volume ratio and low internal resistance, making them ideal for high-density applications. In addition, the capacitors are also suitable for automotive applications, and offer very low internal resistance even at high temperatures. Overall, the TAJA475K016UNJ series of capacitors is an excellent choice for a wide range of applications.
