Power Line Filter Modules are useful for helping control electromagnetic interference (EMI) from power sources. The FTA-80-155-H is an example of such a module and is widely used in AC, DC, audio and video applications. In this article, we\'ll discuss the application field and working principle of the FTA-80-155-H power line filter module.

Application Field of FTA-80-155-H

The FTA-80-155-H is a large package size, three-terminal module with through-hole mounting that is suitable for audio, television, and other power-input and signal-processing applications. This module helps reduce the amount of EMI that can compromise the performance and accuracy of both analog and digital circuits. It also reduces the voltage stress of connected components, thus increasing product reliability. In addition, as a Class B EMI module, it helps improve EMI compliance of products.

Working Principle of FTA-80-155-H

The FTA-80-155-H power line filter module utilizes a combined design of an inductor, capacitor, and varistor. The inductor actively absorbs and reduces noise on the power line, while the capacitor and varistor act as noise-blocking devices. This combination increases the immunity of connected components against interference.

The capacitors in the module are also designed to reduce impedance on the power source, while the varistor helps clamp or absorb transients and surges on the power line. Furthermore, the module is equipped with an FM choke coil in series, which minimizes EMI emissions.

The FTA-80-155-H module is designed for permanent installation, as it is enclosed in a metal can and fitted with screws. This makes it suitable for high voltage environments, such as AC/DC switching power supplies, line filter applications, and power adapters.

Conclusion

To conclude, the FTA-80-155-H power line filter module is designed to provide protection against EMI on power line applications. It features an inductor for active absorption, and a combination of a capacitor and varistor for blocking noise. This combination increases the immunity of connected components against interference and increases product reliability. The module is ideal for permanent installations in high voltage environments.
