FN405-10-02

Power Line Filter Modules, such as the FN405-10-02, are designed to filter EMI from industrial,medical, commercial, and consumer electronic equipment. These filters reduce electromagnetic interference, allowingnoise-free transmission of signals. This article will discuss the application field and working principle of the FN405-10-02 power line filter module.

Application

The FN405-10-02 power line filter module is designed to be used in medical, industrial, and consumer electronic devices. It is suitable for high-density, low-noise applications. It is also suitable for applications involving the transmission of data, such as digital signals, as it has a low parasitic capacitance. The FN405-10-02 can be used in safety-related applications, as it is UL recognized.

Working Principle

The FN405-10-02 power line filter module contains four EMI filter elements, two ferrite cores, and two capacitors. These components work together to suppress interference from high-frequency signals. The ferrite core acts as an inductor, and its inductance forms a high-pass filter, allowing high-frequency signals to pass through while blocking low-frequency signals. The two capacitors work in tandem to form a low-pass filter, allowing low-frequency signals to pass through while blocking high-frequency signals. Together, the four components form a band-pass filter, allowing only a specific range of frequencies to pass through. This ensures that only the desired signal is transmitted, and that unwanted noise is eliminated.

Conclusion

The FN405-10-02 power line filter module is designed to reduce electromagnetic interference and improve the transmission of signals. Its four components work together to form a band-pass filter, allowing only the desired signal to pass through while blocking unwanted noise. The FN405-10-02 is suitable for medical, industrial, and consumer electronic applications, and is also UL recognized for safety-related applications.
