The FC-LX1D is a power line filter module DIP with RoHS certification manufactured by MORNSUN. It is used to suppress high frequency interference on AC power lines from a variety of sources, such as computers, telecommunication systems, process control systems, industrial robots, and digital service equipment. The module uses a combination of three elements - a metal oxide varistor (MOV), an inductor, and a capacitor, in order to achieve the desired amount of noise suppression. The module can handle up to 5A and 500VAC, with a maximum operating frequency range of up to 10 kHz. The filter is highly reliable and long lasting, providing superior performance in filtering high frequency signals. The RoHS certification ensures that the filter is made from safe and non-hazardous materials.
