Its high volumetric efficiency means that it can be integrated into small circuits, and its low equivalent series resistance (ESR) gives it high capacitance values in a variety of applications. It is also a great choice for applications requiring low leakage current and temperature stability.

The TH3C685M016C1700 is well-suited for use in projects involving high-frequency digital circuit designs, as well as in circuits requiring stable performance in the presence of high temperatures. It can also be used in a variety of electronic systems requiring high capacitance values while minimizing physical size. It is often used in automotive components, medical devices, avionics, military hardware, and even consumer products.

Working Principle

The TH3C685M016C1700 operates on a basic electrolytic principle. A tantalum metal oxide is used as a dielectric between two conductive contacts. Silver is typically used as one of the contacts in the capacitor due to its low electrical resistance. The other contact can be made from a variety of conductive materials. When a voltage is applied to the capacitor, the tantalum oxide layer creates a rectifying effect, which allows current to flow in only one direction.

The tantalum oxide layer also acts as a dielectric, which increases the capacitance of the capacitor as the electrical field between the two electrodes increases. This increased capacitance allows the TH3C685M016C1700 to store more energy, giving it higher capacitance values than other similar capacitors.

In addition to its higher capacitance values, the TH3C685M016C1700 also boasts a lower equivalent series resistance (ESR) than other similarly sized capacitors. This lower ESR reduces current spikes, allowing the capacitor to maintain stable performance in high frequency circuits and in the presence of high temperatures.

Conclusion

The TH3C685M016C1700 is a tantalum capacitor designed for high capacitance values and low equivalent series resistance (ESR) performance in a variety of applications. It is well-suited for use in DC-DC converters, power supplies, LED drivers, circuit protection, avionics, and high-frequency digital circuit designs. Its low ESR and high capacitance values make it a popular choice for many applications.
