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).
  • B = Less than full reel
    In tape, 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 (1000 parts per full reel).
