Notes
  1. Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Adc.
  2. DC current that causes an inductance drop of 30% (typ) from its value without current
  3. Leakage Inductance is for the primary, measured with secondary windings shorted together.
  4. 1500 Vrms, one minute isolation (hipot) between primary and secondary.
