Notes
  1. When ordering, please specify packaging codes: e.g. DFT7160-475BLC
  2. Frequency at which the differential mode attenuation equals 3 dB
  3. Inductance measured at test frequency using an Agilent/HP 4286A impedance analyzer and a Coilcraft SMD-A fixture
  4. Irms: Current that causes a 20°C temperature rise from 25°C ambient.
  5. DCR is specified per winding at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  6. 250 Vrms, one minute isolation (hipot) between windings.

 

Termination:

  • RoHS compliant matte tin over nickel over phos-bronze.

Packaging:

  • C = 7" reel, machine-ready 
    EIA-481 embossed plastic tape (250 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.
  • D = 13" reel, machine-ready 
    EIA-481 embossed plastic tape. Factory order only, not stocked (1000 per full reel).
