Tantalum capacitors are electronic components commonly used in electronic circuits. They are composed of a tantalum body, an oxide cathode, a tantalum oxide dielectric and a metallic anode. The type of tantalum capacitor known as a T491A685M016AT is a polarized capacitor, which means that it has a positive and a negative lead, meaning it requires proper placement in a circuit when being used. This type of capacitor has characteristics that allow it to be used in a variety of applications.

The T491A685M016AT is a surface mounted capacitor, meaning it can easily be integrated into circuit boards. This makes it the perfect choice for use in packaging assemblies and computer components where space is at a premium. The capacitor also has a good temperature coefficient which makes it ideal for use in temperature critical applications, such as medical equipment. These features also make it suitable for use in high temperature and high-power circuits.

The capacitance value of the T491A685M016AT varies depending on the voltage being supplied to it, but it usually ranges from 4.7μF to 6.8μF. The maximum voltage is 16V and there is a tolerance rating of ±10%. Therated ripple current is 175mA at 100kHz. This indicates that the capacitor can handle higher levels of operation than standard tantalum capacitors and is suitable for designing power circuits.

The working principle of the T491A685M016AT is based on dielectric absorption. In this process, the capacitor stores charge between two electrodes separated by an oxide dielectric layer. As the voltage increases, the oxide layer absorbs electrons, creating an effective barrier between the electrodes that prevents further charge transfer. This barrier allows the capacitor to store a specific level of charge, which it then use to regulate the output. Consequently, the capacitor helps to reduce the amplitude of ripple and noise in circuits by providing a small reserve of energy.

Overall, the T491A685M016AT is an ideal capacitor for use in a variety of applications. Its small size and good characteristics make it a suitable choice for space-constrained and high-temperature applications. Furthermore, its dielectric absorption mechanism makes it perfect for applications that require low ripple and noise levels. For all these reasons, the T491A685M016AT is an essential component for any electronics designer or technician.
