Notes
  1. Output is with both windings of the secondary connected in parallel.
  2. When ordering, please specify packaging code: e.g. A9967-ALD
  3. Inductance is per winding of the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc. Inductance of the primary, with three windings connected in series is 90 µH.
  4. Leakage inductance is for one winding and is measured with all other windings shorted.
  5. 500 Vrms, one minute isolation between windings.

Termination:

  • RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze. Other terminations available at additional cost.

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.
