Tantalum Capacitors

Tantalum capacitors are widely used in energy storage and conversion applications such as power supply design, high-frequency electronics, computer memory, and consumer electronics. These types of capacitors are made from a combination of an oxide film and layers of metal foils. The oxide film is used to improve the electrical insulation characteristics of the capacitors, while the metal foils allow for greater charge capacity.

TH3A475M016E2900 Application Field

The TH3A475M016E2900 (also known as the X-Cap) is a type of tantalum capacitor designed specifically for DC (Direct Current) applications. It is commonly used in power supply designs and consumer electronics. Its features make it especially suited for use in power supplies, high-voltage DC-DC converters, DC-AC inverters, switched-mode power supplies, and solar power controllers. The advantage this capacitor has over regular electrolytic capacitors is that it has a much lower equivalent series resistance. This reduces losses in the overall power supply design.

TH3A475M016E2900 Working Principle

The TH3A475M016E2900 uses a layer of tantalum powder, surrounded by two metal foils to form the capacitive element. This special composition of metallized layers makes this type of capacitor ideal for DC applications. Tantalum powder possesses superior properties when it comes to energy storage and stability, making it the perfect choice for this application.

Charging the capacitor works as follows: When a voltage is applied to the device, the metal layers are attracted to each other, creating an electrical field between them. This electrical field causes a flow of electrons from one layer to the other, thus creating an electrostatic potential. The electrostatic potential is stored inside the device, and when the voltage is removed, the stored charge is maintained.

This capacitor has a superior dissipation factor, which is beneficial for DC applications. The dissipation factor measures how quickly the stored charge is dissipated. In this case, the dissipation factor is very low, indicating that the stored charge will remain stable over time.

Conclusion

The TH3A475M016E2900 is a tantalum capacitor, specifically designed for DC applications. Its metalized layers and tantalum powder offer superior energy storage and stability, making it an ideal choice for power supply designs and consumer electronics. Thanks to its superior dissipation factor and low equivalent series resistance, it is an excellent choice for those looking for a reliable source of power.
