This article will discuss the applications and working principles of the FN-402B-1-02 Power Line Filter Module.

Application Field

The FN-402B-1-02 Power Line Filter Module is a two-stage, single-ended module used in a variety of power-supply and industrial applications. It has been designed and tested to meet the requirements of EN55011, which sets emission limits for electrical and electronic equipment.

The FN-402B-1-02 is suitable for typical industrial applications up to 125A. It is capable of withstanding high current withstanding requirements, as well as providing noise and surge protection. The module can be used in automotive, consumer, and industrial applications, and can also be used in telecommunications and medical equipment.

The FN-402B-1-02 is most often used in applications such as power supplies, telecommunications systems, and power delivery systems, with the filter module providing an efficient way to filter out unwanted impurities from the power line. The module also helps reduce electrical interference for automotive systems, medical devices, industrial equipment, and consumer electronics.

Working Principle

The FN-402B-1-02 Power Line Filter Module is composed of two series-connected stages, each consisting of an inductor and a capacitor. The first stage is a high-frequency filter that removes noise from the power line above 100MHz. The second stage is a low-frequency filter that reduces noise from 25MHz to 400kHz. The design of the two stages, together with the module\'s distributed capacitors, provides for effective filtering.

The module is designed to reduce the amount of electrical noise generated by high-speed electric motors, switching power supplies, and other sources of electrical interference. The module helps ensure that the power line remains free of impurities and is capable of delivering clean power. In addition, the module is capable of withstanding high inrush currents, which helps to prevent premature component failure in the power line.

In addition to providing noise and surge protection, the FN-402B-1-02 Power Line Filter Module also helps to reduce the effects of electrostatic discharge (ESD). Electrostatic discharge occurs when two electrically charged objects come into contact with each other and an electrical discharge is generated. The FN-402B-1-02 Power Line Filter Module helps to reduce the amount of ESD by providing an ESD protection network.

Conclusion

The FN-402B-1-02 Power Line Filter Module offers many advantages for a variety of industrial and consumer applications. It provides an effective way to filter out impurities from the power line, while at the same time providing noise and surge protection. The module also provides ESD protection for sensitive electronic components. The FN-402B-1-02 is a versatile and reliable module for environments where clean power is essential.
