Data Line EMI Filters  
Leaded  
These filters are designed to virtually eliminate con-  
ducted 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
