Introduction: Power Line Filter Modules are used to protect electronic equipment from the damaging effects of Electro-magnetic interference (EMI) and to reduce conducted emissions. They prevent interference from being conducted on power cables, and also offer immunity to RF signals, thus providing perfect protection and enhanced performance. This article provides an overview of the FN2450B-20-61 Power Line Filter Module, its application field and working principle. Power Line Filter Module FN2450B-20-61 Power Line Filter Module is a device designed for the efficient filtering of high currents, up to 1 amp, in the frequency range 10 to 100 kHz. The use of this filter module in the power supply circuitry of computer systems is essential for ensuring performance and reliability. It consists of a printed circuit board, which contains the capacitors, inductors and diodes used to make up the filter, and a metal enclosure which houses the filter components and holds them in place. The module is connected to the power supply via two screw terminals to ensure a secure connection.The module has a very high current rating and high-frequency performance, making it suitable for a wide range of applications such as mobile phones, gaming consoles, printers, video equipment, and computers. Its size and shape make it ideal for fitting inside existing power supply circuits. FN2450B-20-61 Application Field The FN2450B-20-61 Power Line Filter Module can be used in a variety of circuit applications such as temperature control systems, motor control and power supply circuits. The filter modules enable suppression of Conducted Electromagnetic Interference (CEMI) across a wide frequency range, thus improving the performance of electrical and electronic systems and protecting power supplies from interference. In mobile applications, the filter module can also be used to suppress radio frequency interference (RFI) which can interfere with the performance and reliability of electronics systems. The module is also suitable for use in LED lighting, which requires good EMI performance to prevent interference from being conducted on adjacent cables or components. FN2450B-20-61 Working Principle The FN2450B-20-61 Power Line Filter Module works by providing a path for high-frequency current flow. It has two connections, one to the power source and one to the load, which prevents current from the source entering the load or vice versa. The filter includes multiple capacitors, chokes and diodes, each of which have an optimum impedance in order to provide non-linear filtering. This type of filtering reduces common mode interference, such as high-frequency noise generated by motors, while maintaining low signal distortion.The filter can also act as a noise suppressor by shunting the high frequency current away from the power supply, thus improving the noise immunity of the power system. This makes the filter an ideal solution for areas where EMI is present or where noise immunity is a concern.In conclusion, the FN2450B-20-61 Power Line Filter Module is an efficient and economical solution for suppressing EMI and Improving electrical and electronic equipment performance. It is designed for use in a wide range of applications and offers a reliable and secure connection to the power supply. With its high current rating and high-frequency performance, it is an ideal EMI filter for mobile applications.
