Notes
  1. Inductance is for the primary, measured at 333 kHz, 0.1 Vrms, 0 Adc.
  2. Current that causes a 40°C rise from 25°C when applied to the primary winding with secondary current defined by the turns ratio. Please refer to the datasheet for secondary current info.
  3. Leakage Inductance is for the primary, measured at 333 kHz, 0.1 Vrms with secondary windings shorted together.
  4. Interwinding capacitance from primary to secondary. It is measured from pin 3 to 7 with pin 2 and 6 open at 333 kHz, 0.1 Vrms.
  5. Volt-time product is for the primary, between pins 2 and 3.
  6. 5656 VDC / 4000 Vrms, one minute isolation (hipot) measured between primary and secondary.
