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, 2 Adc.
  3. Sec1 DCR for YA8779 is with windings connected in parallel.
  4. Leakage Inductance is for the primary, measured with secondary windings shorted together.
  5. 1500 Vrms, one minute isolation (hipot) between primary and secondary.
