GA3429-BL_

1. When ordering, please specify packaging code:

2. Inductance is for the primary, measured at 250 kHz, 0.3 Vrms, 0 Adc.

3. Ipk is peak primary current drawn at minimum input voltage.

4. DCR for the secondary is per winding.

5. Leakage inductance measured between pins 3 and 4 with all secondary

6. Turns ratio is with the secondary windings connected in parallel.

7. Output is with the secondary windings connected in parallel. Bias winding

8. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
