메모
  1. Output is with the secondary windings connected in parallel. Bias winding output is 12 V, 20 mA.
  2. Inductance measured at 250 kHz, 0.1 Vrms, 0 Adc.
  3. DCR for the secondary is measured with the windings connected in parallel. For other operating temperatures, use this DCR at Temperature calculator.
  4. Leakage inductance is for the primary and is measured with the secondary shorted.
  5. Turns ratio is with the secondary windings connected in parallel. 
  6. 1500 Vrms one minute isolation primary and bias to secondary.
