Surface Mount, 8 Line
Data Line EMI Filters

  • Virtually eliminates the problem of conducted EMI in data line applications
  • Provides common- and differential-mode noise attenuation
  • Reduces noise by a factor of 32 from 15 MHz to 300 MHz
  • High current (500 mA) versions available
  • 300 Vrms isolation
  • Excellent environmental stability and low cost
  • Consider our PDLF series for 4, 3 and 2 line applications and CCDLF for 10 line applications
  • RoHS-compliant. 260°C compatible. Tin-silver-copper over silver-platinum-glass frit terminations.
  • Samples of each value plus samples of PDLF and CCDLF as well as through-hole versions are available in Coilcraft Designer's Kit D303

1 When ordering, please specify packaging code: e.g. cdf 8500LD.
  Packaging D = 13" machine ready reel
EIA-481 embossed plastic tape (1000 parts per full reel).
B = Less than full reel.
In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead.
2 Frequency at which the differential mode attenuation equals 3 dB
3 Inductance is per winding, tested at 1 MHz.
4 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Interwinding isolation (hipot) tested for one minute.
6 Current rating is for each line.
7 Ambient temperature range: –40°C to +85°C
8 Storage temperature range: Component: –40°C to +85°C
Tape and reel packaging: −40°C to +80°C
9 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
10 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info
