Notes
  1. Calculated output power based on 150 kHz operating frequency. Power varies depending on application.
  2. When ordering, please specify termination and packaging codes: e.g. GA3157-ALD
  3. Inductance is tested between pins 4 and 3 at 500 kHz, 0.5 Vrms, 0 Adc.
  4. DCR is for each half of the primary and secondary.
  5. Leakage inductance is for the primary with both windings connected in series and with the secondary windings shorted.
  6. Based on Bsat of the core at 25°C and number of turns on winding 4-3.
  7. 2500 Vrms primary to secondary isolation.

Termination:

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

Packaging:

  • 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.
