Introduction

173D476X0020YE3 is a tantalum capacitor, which is a type of electrolytic capacitor with excellent performance, widely used in electronic equipments such as computers and cell phones.

Application Field

173D476X0020YE3 tantalum capacitors are used in various electronic circuits where frozen stability of capacitance, low leakage current, high ripple current, and low impedance are required. Such applications mainly include power supplies, switch-mode power supply, and so on. For example, it can be used for buffering or attenuation in time constant circuit or peak detection circuit, for voltage stabilization and transient suppression in power supply, for noise reduction in signal circuit, for charge/discharge in oscillation circuit, and for automatic reset in personal computer.

Working Principle

Tantalum capacitors work by having an electrolyte that is trapped between a semiconductor substrate and an anode. As electricity is passed through them, the electrolyte forms a film at the interface of the electrodes that acts as a dielectric. This dielectric is what contributes to the excellent capacitance stability that they offer. The higher the quality of the dielectric, the better its capacitance stability. At the same time, its very low leakage current is also contributed by the electrolyte.

In comparison to conventional aluminum electrolytic capacitors, the working temperature range and voltage ratings of tantalum capacitors are relatively higher. Besides, the leakage current is lower and the capacitance stability is better. Thanks to its various excellent properties, its application areas are also wider.

Conclusion

To conclude, 173D476X0020YE3 tantalum capacitors feature high quality dielectric that offers excellent frozen stability, low leakage current, high ripple current, and low impedance, and are widely used in various electronic circuits. In comparison to conventional aluminum electrolytic capacitors, the parameters are higher and so is the application range.
