Introduction to the T495D476M025ATE150

Tantalum capacitors are a unique type of capacitor that is widely used in applications such as in the automotive, telecommunications and aerospace industries. The T495D476M025ATE150 is one such device that incorporates tantalum in its construction. This device is deemed to offer some excellent performance characteristics, while also allowing a reasonable price-per-unit. Let’s take a look at how the T495D476M025ATE150 can be used and its design.

Application Field

The T495D476M025ATE150 is a device that can be used in a wide range of different applications. Arguably the most common use for these tantalum capacitors is for power filters in the automotive and industrial sectors. For example, the T495D476M025ATE150 can be used to reduce the amount of high-frequency noise that could be present in a power voltage. This noise can be generated from a number of sources, and this device can act as a mitigation for such issues.The T495D476M025ATE150 can also be used to provide a decoupling function across supply rails. In this function, the device is used to couple two power supplies, allowing them to operate more effectively by reducing the amount of current that can flow between them. This is achieved by ensuring a more stable voltage across the specific application, making it ideal for large circuits that utilize multiple power supplies.The T495D476M025ATE150 is also well suited for active circuit protection roles, such as protecting against electrostatic discharge (ESD). This device is able to act as a shunt to ground and allow the rest of the circuit to remain relatively undamaged during periods of ESD. It is an active protection mechanism that can be used on a variety of different circuit layouts.

Working Principle

So how does the T495D476M025ATE150 actually work? Well, the device is essentially constructed of two distinct elements, which are usually made from a combination of tantalum powder and a ceramic compound. One element of the device is used to form an anode, while the other forms the cathode. The device is then filled with an electrolyte and sealed in a hard-body housing.When a voltage is applied to the device, an electric current is generated through the electrolyte, which is then stored as energy in the anode and cathode elements. Effectively, when a voltage is applied to the device, the applied voltage polarizes the anode and cathode elements in opposite directions, and a charge is stored in the device.The current generated is then stored in the device and can be released when the applied voltage is removed or reduced. This current is then typically used to power other electronic components in the system, such as LED displays.

Conclusion

The T495D476M025ATE150 is a device that incorporates tantalum in its construction, providing exceptional performance characteristics and a reasonable cost-per-unit compared to other types of capacitors. This device can be used in a wide range of applications such as power filters, decoupling, and active circuit protection. The device works by generating a current through its electrolyte, which is then stored in the anode and cathode elements providing it with a charge. This can then be released when the applied voltage is removed or reduced.
