T491D476M016AT4068 Capacitors

Tantalum capacitors are extremely versatile and widely used in various fields of electronics and electrical engineering due to their strong capacitance stability and wide range of available characteristics. The T491D476M016AT4068 is a type of tantalum capacitor, which has been specially designed for military and aerospace applications. This capacitor is capable of operating at temperatures up to 85°C, with a capacitance tolerance of -15% to +10%. It has a high-reliability encapsulated case, which offers better temperature cycling performance and is also resistant to shock and vibration. The maximum voltage rating is 10V. Its unique two-terminal connection makes mounting easier and more reliable.

Capacitors, in general, work on the principle of charge accumulation. When a Voltage is applied across the plates of a capacitor, the opposite charges accumulate on its two plates, leading to an electric field across the plates. This electric field stores energy and is responsible for the capacitor\'s ability to hold charge over time. In the case of tantalum capacitors, the plates are made of a tantalum powder substrate which is combined with a solid non-metallic dielectric material such as polyethylene terephthalate, polyStyrene or polymides. The tantalum powder acts as the capacitor\'s cathode, while the dielectric material is the capacitor\'s anode. When voltage is applied across the plates, electrons flow from the anode to the cathode, leading to the accumulation of charge on the plates.

The T491D476M016AT4068 is generally used in military and aerospace applications, where high reliability is of utmost importance. Its high-reliability encapsulated case and two-terminal connection makes it suitable for these applications, as it can withstand different conditions such as vibrations and temperatures. Due to its high tolerance, this capacitor is ideal for use in power supplies and filters. It is also used in amplifiers and signal conditioning circuits, as well as in DC-DC and AC-DC converters.

The T491D476M016AT4068 is a high-reliability tantalum capacitor designed for military and aerospace applications due to its wide range of characteristics and high tolerance. It works on the same principle of charge accumulation as any other capacitor, with the exception of the material from which its plates are made. By utilizing a tantalum powder and a non-metallic solid dielectric material as its plates, it is able to guard against power glitches, varying ambient temperatures, heavy shock and vibration. Its two-terminal connection makes it easier to mount and its high tolerance ensures reliable operation over a extended period of time.
