메모
  1. Output is with the secondary windings connected in parallel. Bias winding output: 3.3 V, 20 mA.
  2. When ordering, please specify packaging code: GA3429-BLD.
  3. Inductance is for the primary, measured at 250 kHz, 0.3 Vrms, 0 Adc.
  4. DCR for the secondary is per winding.
  5. Leakage inductance measured between pins 3 and 4 with all secondary pins shorted.
  6. Turns ratio is with the secondary windings connected in parallel.
  7. 1500 Vrms isolation from primary and bias to secondary;
    500 Vrms isolation from primary to bias, tested for one minute.
