Notes
  1. When ordering, please specify packaging code: GA3431-BLD.
  2. Inductance is for the primary, measured at 250 kHz, 0.3 Vrms, 0 Adc.
  3. DCR for the secondary is per winding.
  4. Leakage inductance measured between pins 3 and 4 with all secondary pins shorted.
  5. Turns ratio is with the secondary windings connected in parallel.
  6. 1500 Vrms isolation from primary and bias to secondary;
    500 Vrms isolation from primary to bias, tested for one minute.
  7. Output is with the secondary windings connected in parallel. Bias winding output: 5.0 V, 20 mA (GA3430); 3.3 V, 20 mA (GA3431).

Termination:

  • RoHS tin-silver over tin over nickel over phos bronze. Other terminations available at additional cost.

Packaging:
