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 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 D.
