  1. When ordering, please specify termination and packaging codes: e.g. WA8582-ALD
  2. Calculated output power based on 250 kHz operating frequency. Power varies depending on application.
  3. Inductance is for the primary, measured from pins 1 to 2 at 250 kHz, 0.1 Vrms, 0 Adc.
  4. DCR is for each winding of the primary and secondaryat 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  5. Volt-time product is based on 2200 Gauss and the number of turns on winding 1–2.
  6. 1500 Vrms, one minute primary to secondary isolation (hipot); 500 Vrms winding to core isolation..


  • L = RoHS compliant tin-silver over tin over nickel over phos bronze.
  • = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). (Special order, added cost)


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