CDF Series

Surface Mount, 10- and 8-Line Data Line EMI Filters

RoHS compliant
Our CDF Series virtually eliminates conducted EMI in data line applications. It provides common mode and differential mode noise attenuation and reduces noise by a factor of 32 from 15 MHz to 300 MHz for up to 10 lines (5 pairs).
  • Virtually eliminates the problem of conducted EMI in data line applications
  • Provides common mode and differential mode noise attenuation
  • Reduces noise by a factor of 32 from 15 MHz to 300 MHz
  • Excellent environmental stability and low cost
  • 300 Vrms isolation (hipot) for one minute
Consider our PDLF Series for 4-, 3- and 2-line applications

  1. When ordering, please specify termination and packaging codes: e.g. CDF10000LD.
  2. Frequency at which the differential mode attenuation equals 3 dB
  3. Inductance is per winding, tested at 1 MHz.
  4. Current rating is for each line.
  5. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  6. Interwinding isolation (hipot) tested for one minute.


  • L = RoHS compliant tin-silver-copper over tin over nickel over phos bronze.
  • S = non-RoHS tin-lead (63/37). (Special order, added cost)


  • D = 13" machine ready reel
    EIA-481 embossed plastic tape (1000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = Less than full reel. 
    In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
