  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.


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


  • 13" machine-ready reel
