메모
  1. Output is with the secondary windings connected in parallel. Bias winding output is 12 V, 20 mA.
  2. When ordering, please specify a packaging code: JA4667-ALD.
  3. Inductance is measured at 250 kHz, 0.2 Vrms, 0 Adc.
  4. DCR for the secondary is measured with the windings connected in parallel.
  5. Leakage inductance is for the primary and is measured with the secondary shorted.
  6. Turns ratio is with the primary windings and secondary windings connected in parallel.
  7. 1500 Vrms isolation from primary and bias to secondary.
