TTDLF
Data Line EMI Filters

NOTE  As of August 2015, the TTDLF 10000 is no longer available; please consider our CCDLF 10000L. For the 2, 3 and 4 line versions, we offer an even more economical version of this series: PDLF. It is electrically identical and fits the same land pattern. Existing customers will continue to be supported.
  • Virtually eliminate the problem of conducted EMI in data line applications
  • Provide common- and differential-mode noise attenuation
  • Reduce 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
  • 4, 3 and 2 line versions
  • RoHS-compliant. 260°C compatible. Tin-silver-copper over silver-platinum-glass frit terminations

1 When ordering, please specify termination and packaging codes: e.g. TTDLF 2500LC.
  Termination: L = RoHS compliant tin-silver-copper over silver-platinum-glass frit.
Special order, added cost: S = non-RoHS tin-lead (63/37)
  Packaging: C = 7" machine ready reel.
EIA-481 embossed plastic tape (500 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 C instead.
D = 13" machine ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2200 parts per full reel).
2 Current rating is for each line.
3 Inductance is per winding, tested at 1 MHz.
4 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
5 Operating temperature range −40°C to +85°C. Details
6 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.
