Notes
  1. When ordering, please specify packaging code: e.g. FA2636-ALD
  2. Inductance is for the primary, measured at 250 kHz, 0.2 Vrms, 0 Adc.
  3. DCR for the secondary is per winding.
  4. Leakage inductance measured between pins 3 and 2 with all other pins shorted.
  5. Turns ratio is with the secondary windings connected in parallel.
  6. 1500 Vrms, one minute isolation from primary and auxiliary to secondary.

Termination:

  • RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations.

Packaging:

  • 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.
