Power Line Filter Modules are important components in many electronic systems and systems that are exposed to the environment where there is electromagnetic interference (EMI). The FN3026HP-20-71 is an industry leading filter module that offers high performance and superb reliability for noise suppression in many applications. This article will explore the FN3026HP-20-71 power line filter module application field and working principle.

FN3026HP-20-71 Application Field

The FN3026HP-20-71 power line filter module is designed to be used in a range of consumer electronics, industrial control applications, automotive and home appliances. It can help reduce power line noise interferences from household appliances to dc power supply control systems, including computers, home entertainment systems, heavy-duty electrical tools, motor regulation systems, projectors, lighting equipment, and commercial product testing and development systems. Additionally, it is suitable for use in any application where EMI or RFI related noise is present.

FN3026HP-20-71 Working Principle

The FN3026HP-20-71 power line filter module is built with a ferrite-core inductor and two capacitors. It utilizes a filtering design based on an inductor and two capacitors, connected in a single-stage, low-pass filter circuit. This series-connected filter system is effective in eliminating conducted electromagnetic noise which is injected or coupled into the power/ground line. The inductor works as a shield to block the noise and the capacitor stores the energy and then releases it as the noise pulses pass through the system. The two capacitors need to be of equal value to provide a symmetric filter configuration, allowing the offered current-mode and signal-mode noise suppression to be of equal magnitude and thus allowing this module to be effective in elimiating noise from both the power and ground lines.

The FN3026HP-20-71 power line filter is also built with a flexible shielded casing to shield the filter from external EMI noise and provide it with effective grounding. It features a 5V DC voltage rating and a maximum current rating of 3 amps, making it suitable for most common power and control applications. Additionally, its compact and lightweight design make installation simple and efficient, offering equal noise suppression performance and high durability.

Conclusion

The FN3026HP-20-71 power line filter module is an effective solution for eliminating noise from power/ground lines in many consumer electronics, industrial control applications, automotive and home appliances. Its unique single-stage filter design, consisting of an inductor and two capacitors of equal value, works together to reduce conducted electromagnetic noise in both current-mode and signal-mode. Additionally, its flexible shielded casing and lightweight design make it an efficient and reliable noise reduction solution.
