.Power Line Filter Modules: FN3258H-42-47 Application Field And Working PrinciplePower line filter modules are an integral part of protecting sensitive electrical equipment from EMI. What’s more, this protection can be provided in a single, compact module. One of these modules, the FN3258H-42-47, is particularly well suited for use in a variety of applications. In this article, we will discuss the application fields and working principle of the FN3258H-42-47 power line filter module.First, let’s discuss the application fields of the FN3258H-42-47. It is well suited for use in high-end medical, industrial, and telecommunications equipment. It is also especially suited for high-end integrated circuit applications, where health and safety are paramount. Furthermore, it is well suited for use in power supplies, data communication systems, and pulse amplifiers.When it comes to its working principle, the FN3258H-42-47 works by suppressing the noise on both the AC power line and the DC power line. On the AC power line, it attenuates high frequency noise above 100kHz and it also attenuates high frequency noise between 20MHz – 30MHz. On the DC power line, it attenuates noise up to 1MHz. Furthermore, it has an insertion loss of -20dB or less at 20MHz – 30MHz. This ensures that the noise that enters the sensitive electrical equipment is kept at an acceptable level.In addition, it also provides surge protection. It has surge current levels up to 20kA and surge voltages up to 360V. This ensures that even if there is a sudden surge in the power line, the sensitive equipment will be protected against damage.Finally, the FN3258H-42-47 also has a built-in thermal fuse, which will cut off the supply of power to the module if it detects an overheating condition. This prevents further damage to the module and ensures that the sensitive equipment remains safe.In conclusion, the FN3258H-42-47 is an ideal choice for a variety of applications. It can provide effective EMI protection, surge protection, and it also has a built-in thermal fuse for added safety. It is well suited for use in high-end medical, industrial, and telecommunications equipment, as well as for high-end integrated circuit applications.
