Tantalum capacitors, classified as either wet or solid, are an important category of capacitors that have been relied on for decades in a variety of electronic applications. These capacitors are available in both axial and radial leaded formats and are typically the most reliable solution for demanding, high-performance applications such as power supply filtering, industrial automation, and military electronics.
Tantalum-Polymer capacitors, also known as polymer capacitors, are the most recent innovation of the tantalum capacitor family. These capacitors have an anode formed by sintering powder of Tantalum with a thin-film insulation, making them smaller than standard tantalum capacitors while still delivering the same level of reliability. The thin-film insulation allows for a much higher packing density and a lower profile than traditional tantalum capacitors, making them a great fit for applications with board-space constraints.
T543V685M050ATS0657280 is a type of tantalum-polymer capacitor with a maximum voltage rating of 6.3 V and a capacity of 5.0 μF. The C0G safety standard temperature coefficient is -15±30ppm/℃, and its capacitance tolerance is ±20%. The package size of the capacitor is EIA Code A3-3.5x7.5 and it has an SMD shape and a size of 3.5 x 7.5 mm.
T543V685M050ATS0657280 application field includes Automotive electronics, Industrial power, Portable devices, and other areas. The tantalum-polymer capacitor is perfect for high-temperature applications, high-reliability requirements, and board-space constraints. It is widely used in the Power Management Units (PMU), Audio Electronic Circuits, DC-DC Converters, and Automotive Circuits.

The working principle of Tantalum-Polymer capacitors is similar to that of wet tantalum capacitors. They are a type of electrolytic capacitor that uses an oxide layer on a tantalum metal as the dielectric medium. This oxide coating forms a true capacitor with a low equivalent series resistance (ESR) and a high capacitance value. The oxide film is a semi-conductor, allowing the capacitor to operate at lower voltages. It also has an extremely high dielectric constant, enabling a high capacitance value to be achieved in relatively small devices.
Tantalum-Polymer capacitors are polarized and require a positive voltage on the positive terminal and a negative voltage on the negative terminal. Cathode voltage must always be higher than the anode voltage in order for the capacitor to operate. The electrode of this type of capacitors is made by tin/lead plating which increases conductivity as well as protection from environmental conditions. This ensures that the capacitor has longer life and better performace.
Tantalum-Polymer capacitors are stable over a wide range of temperatures and can handle high ripple currents. They are different from traditional wet tantalum capacitors in that they are not susceptible to moisture or humidity. They require no external heat or pressure for soldering, which makes them ideal for surface mounting applications. The thin- film insulation layer also makes them highly resistant to vibration and shock.
In conclusion, T543V685M050ATS0657280 is a type of tantalum-polymer capacitor with high reliability and excellent performance, which makes it a great fit for demanding applications. It can be used in areas such as Automotive electronics, Industrial power, Portable devices, and more. Its excellent resistance to temperature changes and vibration, high capacitance, low ESR, and low profile makes it perfect for applications with board-space constraints.
