Tantalum capacitors are a type of capacitor that use a manganese dioxide (MnO2) anode and a tantalum metal cathode, with an electrolyte typically composed of an aqueous solution of a non-aqueous organic solvent. They come in surface-mount, leaded, small-outline, chip, wet-slug, and wet-leaded formats, and offer superior advantages over other capacitor types. Unlike aluminum electrolytic capacitors, they have low equivalent series resistance (ESR) and low leakage current. Due to their excellent temperature stability and high capacitance, they are widely used in applications where frequency response and temperature stability are important.

173D686X0010YE3 is one of the typical tantalum capacitors. It is a polarized capacitor in a "D" package, released by AVX, an American manufacturer of passive electronic components, and is widely used in power supply and signal filtering applications. As its name indicates, its capacitance is 6.8uF, its working voltage is 10V, and its tolerance is 10%. According to its datasheet, its temperature range is −55 °C to 125°C. Its standard ESR is 16mOhm at 100kHz and 10V. This type of capacitor is also designated as a "Bi-polar" capacitor for its different application field from non-polarized tantalums.

The application field of 173D686X0010YE3 can be widely found in various electronic products, such as in voltage-regulator modules (VRMs) and high-efficiency DC-DC converters, where its high capacitance and low ESR guarantee a voltage stability. It is also used in the power supply of other electronic devices, such as LCD backlight supply, LED drive supply, etc. In addition, it can be used in signal-filtering circuits, such as audio filters, where its low leakage current offers improved audio-fidelity and suppression of high-frequency noise.

The working principle of 173D686X0010YE3 is quite simple. When it is connected in a circuit, it charges up in proportion to the voltage applied across its terminals. When the applied voltage is high, a higher amount of charge is stored, thus increasing capacitance. When the voltage across its terminals is reduced, the stored charge goes down, thus reducing capacitance and ESR. In addition, the reverse leakage current is significantly reduced when the voltage is reduced. All these features make it ideal for a large variety of applications.

All in all, 173D686X0010YE3 belongs to the category of tantalum capacitors, and its features give it great advantages over other capacitor types. Its application field can be widely found in the power supply and signal-filtering circuits of various electronic devices, and its working principle is quite simple and straightforward. It is reliable and features excellent temperature stability and high capacitance, making it one of the most popular capacitor types used today.
