Notes
  1. Inductance is for primary windings measured between pin 1 and 3 at 10 kHz, 0.05 Vrms, 0 Adc.
  2. Leakage inductance measured between pins 1 and 3 at 100 kHz, 0.1 Vrms with secondary pins shorted.
  3. Volt-time product is for the primary, between pin 1 and 3.
  4. One minute isolation (hipot) primary windings to secondary windings.
