Notes
  1. Inductance is for the primary, measured at 300 kHz, 0.1 Vrms, 0 Adc.
  2. Minimum inductance is for the primary, measured at 300 KHz, 0.1 Vrms, 3 Adc.
  3. Leakage Inductance is for the primary, measured with secondary windings shorted together.
  4. 1500 Vrms, one minute isolation (hipot) between primary to secondary.
