Description: An EMI filter is an electronic device that is used passively to suppress conducted interference that is present on a signal or power line. EMI filters are used to suppress interference generated by the device or by other devices to make a device more immune to interference signals present in the environment. Most EMI filters consist of components that suppress differential and common mode interference. Applications for EMI filters:Data lines,Secondary power supply lines for digital audio / video and communication equipment,Computer mainboards,USB hubs,printer,Hard drives,CD and DVD ROMs,AC adapter,Electronic musical for instruments EMI power filter is a passive two-way network. It is an electrical device that effectively filters out the frequency of a specific frequency in the power supply or the frequency other than that frequency. One end of it is connected to the power supply and the other end is connected to the load. Specification: Rated current: 6A. Working frequency: 50 / 60Hz. Nominal voltage: 250V AC. Hello -Pot-Test (2senond): 1760VDC (PN) 2000VAC (PE). Temperature range: from -25 degrees to +85 degrees. Package included: 1 * EMI filter.
