  1. Output is with the secondary windings connected in parallel. Output of the drive winding is 6 V, 10 mA. Output of the bias winding is 11.2 V, 20 mA.
  2. When ordering, please specify a packaging code: JA4387-ALD.
  3. Inductance is measured at 250 kHz, 0.1 Vrms, 0 Adc. 
  4. Peak primary current drawn at minimum input voltage.
  5. DCR for the primary and the secondary is measured with windings connected in parallel.
  6. Leakage inductance is for the primary, measured with the windings connected in parallel and the secondary windings shorted.
  7. Turns ratio is with the primary windings and secondary windings connected in parallel.
  8. 1500 Vrms isolation from the primary and bias windings to the secondary.
