T491A105K016AT2478 is a type of tantalum capacitor.  It is a polarized electrolytic capacitor housed in a cylindrical shape made of epoxy resin and constructed with two cap-shaped electrodes. A tantalum capacitor consists of tantalum material, manganese dioxide electrolyte, and other components. Its dielectric is formed when a potential is applied to the tantalum anode, which creates a thin oxide film on the tantalum material.

T491A105K016AT2478 capacitors are used in situations where a specific capacitance is needed across a high voltage range and in the very tight spaces or enclosures where it fits in smoothly. This capacitor is well suited for switching application because of its very fast charging and discharging characteristics. T491A105K016AT2478 is also well suited for high-frequency applications due to its high-frequency characteristics and very low ESR at higher frequencies.

T491A105K016AT2478 capacitors have strong ripple resistance, making them highly durable and reliable in applications with high current ripple.  Additionally, it provides a very low series inductance when used in high frequency application. This enables it to provide better signal integrity in the signal path, which is not possible with conventional electrolytic capacitors. Because of their low leakage current, these capacitors are also well suited for analog signal path applications in which high accuracy and low capacitance drift is desired.

The working principle of T491A105K016AT2478 capacitors involves the use of an electrolytic substance between the two electrodes. When an electrical voltage is applied across the two electrodes, a layer of oxide material is formed on the tantalum anode. This oxide layer is used as the dielectric of the capacitor and determines its electrical characteristics. The dielectric layer affects not only the capacitance of the capacitor but also its leakage current, insulation resistance, and other factors. The oxide layer is extremely thin and must be meticulously maintained to ensure the reliable and long lasting performance of the capacitor.

T491A105K016AT2478 capacitors are versatile and can be used in various applications including automotive, industrial, medical, telecom, lighting, military and avionics. In automotive applications, they can be used in generator to reduce noise and ripple, alternator regulator to extend battery life, and in lighting, such as headlights to provide more consistent brightness. In industrial and telecom applications, they can be used in power supplies for better efficiency, memory systems for better data retention, and robotics for smooth operation.

In the medical field, T491A105K016AT2478 capacitors are extensively used for implantable medical devices, such as pacemakers and hearing aids, where capacitors must withstand high temperatures and humidity and provide reliable performance over a long period of time. In the military and avionics industry, they are used in various applications such as radar systems, aircraft, missiles and satellites to reduce weight, increase system performance, and to meet stringent environment and performance requirements.

T491A105K016AT2478 capacitors, due to their unique attributes, are well suited for use in a wide range of applications. They provide high capacitance values, low ESR and leakage current, low dissipation factor, low inductance, and robust high temperature performance.
