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