Notes
  1. When ordering, please specify packaging code: e.g. CR7983-CLD
  2. Inductance is for the primary, measured from pins 12 – 11 at 1 kHz, 0.1 V.
  3. DCR is for each winding of the primary and secondary.
  4. Leakage inductance is for the primary windings, measured from pins 12 – 11 with all secondary windings shorted.
  5. Based on VIN max, FSW min and number of primary turns.
  6. Isolation: 5000 Vrms, one second primary to secondary.

Termination:

  • Tin-silver-copper over tin over nickel over phos bronze.

Packaging:

  • D = 13" machine-ready reel
    EIA 481 embossed plastic tape (175 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 D instead.
