Tantalum capacitors are a type of electrolytic capacitor, a device that stores electric charge, consisting of capacitors with two electrodes filled with a conductive electrolyte. The 173D185X9020VW is a popular model of tantalum capacitor, used for a wide range of applications. This article will discuss the application field and working principle of the 173D185X9020VW.

Application Field

The 173D185X9020VW is a popular choice for digital and power supply applications, often deployed because of its low equivalent series resistance, or ESR. Tantalum capacitors also have much lower leakage current than other types of capacitor and have excellent thermal stability, making them ideal for automotive applications. These capacitors can also be used in a variety of other applications including audio crossover, high impedance power supplies and low frequency oscillator circuits.

The 173D185X9020VW is also often used in low and mid frequency pulse circuits, pulse noise filters, bypass filters and frequency matching circuits. The capacitor is also deployed in the power supply, signal coupling, frequency discrimination and buffering stages of switching and linear power supplies.

Working Principle

Tantalum capacitors work on the principle of electrolytic breakdown, where two electrodes (typically in the form of two metallic plates) are placed in an electrolyte solution. Once power is applied to the two electrodes, electrolytic breakdown occurs, creating a film of tantalum pentoxide between the two plates. This film forms a dielectric layer which enables the capacitor to store electric energy.

The 173D185X9020VW is a tantalum capacitor, a type of electrolytic capacitor, which means it has an open circuit voltage of around 25 VDC, making it suitable for many applications. The capacitor is constructed of an anode with a tantalum dioxide layer as a dielectric, and a cathode with a manganese dioxide layer, also acting as a dielectric. The anode and cathode are separated by a spacer and filled with a live electrolyte solution, providing the capacitance and voltage rating of the capacitor.

The 173D185X9020VW relies on modern high-performance components, made of a stainless steel casing for heat dissipation and low internal resistance, increasing their efficiency and reliability. The capacitor has an excellent endurance, reaching up to 2,000 hours of operation at high temperatures.

Conclusion

The 173D185X9020VW is a popular and reliable tantalum capacitor, widely employed in digital, power supply and automotive applications. The capacitor is constructed with an anode and cathode filled with electrolytic solution and separated by a spacer, enabling it to store electric energy. The capacitor is also constructed with modern components, such as a stainless steel casing, providing excellent endurance and efficiency.
