Notes
  1. Aux winding output is 20 mA.
  2. Inductance is for the primary, measured at 300 kHz, 0.3 Vrms.
  3. DCR for the primary is with the two windings connected in series (pin 2 and 3 to be connected).
  4. Leakage inductance is for the primary windings with the secondary windings shorted.
  5. Turns ratios are with the primary windings connected in series (pin 2 and 3 to be connected).
  6. Isolation (hipot) is measured from primary to secondary for one minute.

Termination:
