Notes
  1. Output for the secondary is between pins 7 and 10. Bias winding output is 10 V, 20 mA. Sync winding output is a 5 V Sync FET gate drive signal.
  2. When ordering, please specify packaging code: e.g. NA6223-ALD
  3. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc.
  4. Ipk is the peak primary current drawn at minimum input voltage.
  5. DCR for the primary is from pin 1 to pin 2, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  6. Leakage inductance if for the primary and is measured with all other windings shorted.
  7. Turns ratio is with the primary windings connected in series.
  8. 1500 Vrms, one minute isolation from the primary and bias windings to the secondary.

Termination:

  • RoHS-compliant  260°C compatible. Tin-silver (96.5/3.5) over tin over nickel over phos bronze terminations.

Packaging:

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