T491D687M004AT4777 is a type of tantalum capacitor manufactured by KEMET. It is a type of solid electrolytic capacitor which typically functions as a feed-through decoupling capacitor used for high frequency applications. It is a type of capacitor which can store electrical energy in the form of a static charge, and is mainly used to maintain a certain level of voltage in high frequency electrical circuits. This capacitor is capable of providing high sensitivity performance and reliable long-term operation.

They are available in a variety of sizes and shapes, ranging from a few nanofarads to milifarads. The capacitors are further classified based on their construction detailing, like their anode material, electrolyte type, cathode material, dielectric type, and others. The capacitor\'s packaging is also based on several factors, like the type of metal alloy used in the casing, its dielectric layer’s thickness, and its voltage rating.

The T491D687M004AT4777 capacitor is often used in the Electronics Industry for a variety of applications. It is a high-precision device, and its high accuracy and temperature stability make it suitable for a wide range of applications. It is particularly popular in the defense and aerospace industries because of its extreme precision and reliability.

The capacitor has a capacitance of 6.8uF and a voltage rating of 16 VDC. It is constructed from a tantalum anode, an electrolyte and a tantalum cathode. This type of capacitors is usually used in general Electronic applications, such as power supply circuits and timing circuits. They are also used in communication devices, computer systems, and motor control devices.

The working principle of the T491D687M004AT4777 capacitor is based on the fact that it stores electrical energy in its dielectric material, which can then be discharged when necessary. The capacitor has two electrical connections: the anode and the cathode. The anode is connected to the positive terminal of the power source, while the cathode is connected to the ground. When a Voltage passes through the capacitor, it will cause an equal but opposite charge to accumulate on the opposite sides of the dielectric material, resulting in a voltage differential. This voltage differential can then be used to power electronic components.

The capacitance of a capacitor is important when choosing one for a particular application. The capacitance of the T491D687M004AT4777 is 6.8uF and it has a voltage rating of 16 VDC. This makes it suitable for most high current applications. The physical size of the capacitor also plays a role in determining its capacitance and voltage rating, as the thickness of the dielectric layer affects these parameters. Other parameters such as the soldering points and mounting holes also affect the performance of the device.

The T491D687M004AT4777 is an excellent capacitor for a wide range of high-frequency applications. It is reliable and offers high precision performance. It can be used in a variety of electronics applications including power supply circuits and communication devices. Its high capacitance and voltage rating make it suitable for many high current applications. With its multiple terminal connection points and mounting holes, it can easily be integrated into a circuit board layout.
