Through Hole Data Line EMI Filters
These filters are designed to virtually eliminate conducted EMI in data line applications. They provide exceptional common mode noise reduction from 5 MHz to 300 MHz while passing signal line data frequencies below 200 MHz with minimal attenuation. These low resistance filters feature excellent electrical isolation, environmental stability and low cost. Optional covers make them auto insertable. They also meet IEC 695-2-2 needle flame test requirements. There are 8, 4, 3 and 2-line versions with DC current capacity of 100 mA (DLF x000 series) or 500 mA (DLF x500 series). Coilcraft Designer’s Kit D303 contains four samples of all values shown plus samples of our PDLF and CCDLF surface mount filters. To order, contact Coilcraft or visit http://order.coilcraft.com.
