Power Line Filter Modules are a type of electrical device used in power supplies to protect electronic circuits and devices connected to it from interference by other electrical circuits or devices. They are used in applications such as motors, relays, and lighting, and serve to filter out electrical noise, both conducted and radiated, from unwanted sources, while allowing the desired signal to pass. The FN351H-64-33 is a type of Power Line Filter Module, which is commonly used in a variety of consumer and industrial electronics applications.

FN351H-64-33 Application Field

The FN351H-64-33 is rated and designed to protect a variety of low frequency circuits such as AC supply, Motors, Generators, Relays and Actuators, and also optics-based systems, from Electro-Magnetic Interference (EMI). It is designed to provide protection for any device which would otherwise be vulnerable to EMI in a range of frequencies, from as low as 10 kHz to 1GHz.

The FN351H-64-33 is typically found in applications designed for consumer and industrial electronics as it has a very low insertion loss and wideband performance capabilities. This line filter module is also used in environments with high ambient temperatures, such as oil and gas fields, and operates satisfactorily at temperatures as high as 105°C. In addition, it is resistant to vibration and shock, something which is essential for many industrial applications, such as automotive and construction machinery.

FN351H-64-33 Working Principle

The FN351H-64-33 employs a two-stage filtering process to achieve its high levels of EMI suppression. The first stage is an EMI filter, which is used to block RFI and EMI signals from the power lines. This is coupled with a second stage of suppression, which uses a combination of chokes and capacitors to further reduce EMI interference. This two-stage approach ensures that the FN351H-64-33 has the ability to filter out both conducted and radiated EMI. This unit also uses a combination of spark gap technology and safety fuses to protect against high incoming voltage surges.

The FN351H-64-33 is designed to have low insertion loss, meaning that it does not degrade signal quality. This makes it ideal for use in delicate applications, where even the slightest interference can have a disastrous effect. It is also designed to have a wide frequency range, allowing it to be suitable for use in many different applications. The FN351H-64-33 also has an attractive form factor, making it suitable for installation in tight spaces, and it is relatively inexpensive, making it an attractive solution for many consumer applications.

Conclusion

In conclusion, the FN351H-64-33 is an ideal Power Line Filter Module for many consumer and industrial electronics applications due to its low insertion, wideband performance and high temperature resistance. Its two-stage filtering process ensures that it is highly effective at suppressing both conducted and radiated EMI, and it is relatively inexpensive. Its attractive form factor makes it suitable for installation in tight spaces, making it an ideal choice for many applications.
