  1. Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Adc.
  2. Isat: DC current that causes the primary inductance drop of 30% (typ) from its value without current.
  3. Leakage inductance is for the primary winding with the secondary windings shorted.
  4. Isolation (hipot) measured between windings for one minute.
