Power line filter modules are widely used in power source line and peripheral circuits to filter out the high-frequency harmonic interference signals that are present in the power line. The power line filter module can reduce interference in the power line, thereby providing a better environment for the operation of power electronic equipment. The FTA-100-223-HS is a type of power line filter module. This article will discuss the application field of this module and its working principle.

Application Field

The FTA-100-223-HS is suitable for household and office power supply systems, and is mainly used in power sources such as host computers and peripheral devices. It is used to filter out high-frequency harmonic interference signals from the power line, and thereby achieve the effect of suppressing EMI (Electro Magnetic Interference). The noise reduction rate is up to 20-30dB. It can also be used in the power supply system of small communication devices, monitoring systems, and the power supply system of electronic equipment.

Working Principle

The FTA-100-223-HS power line filter module works by passing a current through two inductors and three capacitors to generate a low-pass filter circuit, which can filter out high frequency signals. The inductors are designed as a radial winding structure, which has a stronger shielding effect and better performance. When the high-frequency signal passes through the inductor, the inductance of the inductor increases, and the high-frequency signal is stored in the capacitors. Then, this stored energy is dissipated through the resistors. Finally, the high frequency signal is filtered out and the low frequency signal is allowed to pass through. This module also has a common-mode inductor, which can reduce the influence of frequency fluctuations and strengthen the signal rejection performance of this module.

Conclusion

In conclusion, the FTA-100-223-HS is a power line filter module that is widely used in power source lines and peripheral circuits in order to filter out high-frequency harmonic interference signals. It provides a good suppressing effect to EMI, and is suitable for household and office power supply systems, as well as small communication devices, monitoring systems, and the power supply system of electronic equipment. Its working principle is to generate a low-pass filter circuit by passing current through two inductors and three capacitors, which can effectively filter out high frequency signals.
