Tantalum capacitors are electronic components that are widely used in electronic circuit designs and electronic appliances. In particular, the application of this type of capacitor has become more important in digital applications due to its low parasitic capacitance and low inductance. This application field and working principle of the capacitor with the code 173D473X0035UWE3 is discussed in this article.

Introduction

Tantalum capacitors are non-polarised capacitors that are generally made of a solid tantalum base metal, with a thin dielectric oxide layer. These capacitors have unique characteristics due to their high specific capacitance/volume ratio,high voltage-temperature stability,and their ability to work with low-frequency signals. Due to their excellent electrical characteristics, these capacitors are commonly found in the telephony, military and aerospace, automotive, medical and industrial markets. Moreover, these capacitors are suitable for applications at temperatures ranging from -55°C to +125°C.

The Construction of Tantalum Capacitors

The code 173D473X0035UWE3 is a type of tantalum capacitor that is made from a solid tantalum base with a dielectric oxide layer that consists of either tantalum pentoxide (Ta2O5) or niobium pentoxide (Nb2O5). These capacitors are constructed in the same way that all other tantalum capacitors are built. The construction of a tantalum capacitor consists of a solid tantalum base, typically with a thin ply of tantalum pentoxide (Ta2O5) or niobium pentoxide (Nb2O5) dielectric oxide layer. The dielectric oxide layer is covered by a second electrode, which is a combination of a metallic layer and a positive layer of either manganese dioxide (MnO2) or silver. The second electrode serves to increase the capacitance of the capacitor.

Application Field and Working Principle

Tantalum capacitors with the code 173D473X0035UWE3 are generally used in high capacitance/low voltage general purpose applications. Generally, these capacitors are applied in situations which require high signal integrity and low parasitic capacitance. These capacitors are used in applications that require low ESR, such as in amplifiers and filters. Furthermore, these capacitors can be used in applications where the temperature range is low, as the dielectric oxide layer remains stable and maintains its electrical properties even when the temperature changes.

The working principle of these capacitors is very similar to other types of tantalum capacitors. The two electrodes provide a space in between, where an electric field can be generated. The charge build-up on each of the electrodes creates an electric potential across the dielectric oxide layer, resulting in a capacitance that is determined by the electrode area and the dielectric material’s dielectric constant (K). This capacitance can then be used as an energy storage device for signals.

Conclusion

Tantalum capacitors with the code 173D473X0035UWE3 are generally used in general purpose applications that require low parasitic capacitance and low ESR. These capacitors feature a solid tantalum base with a dielectric oxide layer covered by an electrode consisting of a metallic layer and a positive layer. The working principle of these capacitors is similar to other types of tantalum capacitors, where the two electrodes provide an electric field for a capacitance to be determined by the electrode area and the dielectric material’s dielectric constant.
