SMT Data Line EMI Filters – CDF
• See our PDLF series for 4, 3 and 2-line EMI filters
• Exceptional common mode noise attenuation from 15 MHz
to 300 MHz; passes signal line data below 300 MHz with
minimal attenuation
• DC current capacity of 500 or 100 mA.
• Excellent electrical isolation – 300 Vrms for 1 minute

1. When ordering, please specify termination and packaging codes:
CDF10000LD
Schematics
Termination L = RoHS compliant tin-silver-copper over tin over nickel
over phos bronze. Other terminations available at
additional cost.
Special order: S = non-RoHS tin-lead (63/37).
Packaging 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.
2. Frequency at which the differential mode attenuation equals −3 dB
3. Inductance shown for each winding, measured at 1 MHz
4. DCR is for each winding.
5. Interwinding isolation (hipot) tested for one minute.
6. Current rating is for each line.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
