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
