Document 149 DataLineEMIFilters-Leaded These filters are designed to virtually eliminate the problem of conducted EMI in data line applications. They provide exceptional common mode noise attenuation from 5 MHz to 300 MHz while passing signal line data frequencies below 200 MHz with minimal attenuation. These low resistance filters have been designed for excellent electrical isolation, environmental stability, and low cost. An optional cover makes them compatible with auto insertion equipment. Coilcraft data line EMI filters come in 8, 4, 3 and 2-wire versions with DC current capacity of 100 mA (DLF X000 series) or 500 mA (DLF X500 series). Coilcraft Designer's Kit D103 contains samples of all 100 mA values shown plus surface mount versions. To order, please contact Coilcraft. Specifications Max. DCR Current L/winding Max.
