Notes
  1. Output is of the secondary winding. Auxiliary winding output:20 V, 10 mA.
  2. When ordering, please specify packaging code: e.g. PA6284-ALD
  3. Inductance measured at 100 kHz, 1.0 Vrms, 0 Adc
  4. DCR for the secondary is with the windings connected in parallel, measured at 25°C. For other
    operating temperatures, use this DCR at Temperature calculator.
  5. Leakage inductance is for the primary and is measured with the secondary shorted.

Termination:

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

Packaging:

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