Notes
  1. Inductance is for the primary, measured at 250 kHz, 0.5 Vrms, 0 Adc.
  2. DC current at 25°C that causes an inductance drop of <15% (POExx51Q) and <15% (POExx40Q) from its value without current.
  3. Leakage inductance is for the primary with the secondary and aux windings shorted.
  4. 1500 Vrms, 1 minute isolation (hipot) between primary and auxillary and auxillary to secondary.
  5. Output is for the secondary. Output of the aux winding is 12 V, 30 mA.
