Notes
  1. When ordering, please specify packaging code: e.g. PA6547-ALD
  2. Inductance is for the primary, measured from pins 4– 3 at 1 kHz, 0.1 Vrms.
  3. DCR is for each winding of the primary and secondary
  4. Leakage inductance is for the primary windings, measured from pins 1– 4 with all secondary windings shorted.
  5. Based on Bsat of the core at 25°C and the number of turns on winding 4-3.
  6. Isolation: 2500 Vrms primary to secondary; 1250 Vrms windings to core

Termination:

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

Packaging:

  • D = 13″ machine ready reel. EIA-481 embossed plastic tape (600 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.
