Notes
  1. When ordering, please specify packaging code: e.g. CQ7584-ALC
  2. Frequency at which the differential mode attenuation equals 3 dB
  3. Inductance shown for each winding, measured at 10 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4263B LCR meter or equivalent.
  4. Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
  5. DCR is specified per winding at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  6. Isolation (hipot) measured with 3 mA applied for two seconds

Termination:

  • RoHS compliant tin-silver-copper over tin over nickel over phos bronze.

Packaging:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (250 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).
