1. When ordering, please specify packaging code:

2. Inductance measured at 250 kHz, 0.7 Vrms, 0 Adc.

3. Peak primary current drawn at minimum input voltage.

4. DCR for the secondary is with windings connected in parallel.

5. Leakage inductance is for the primary and is measured with the secondary shorted.

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

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

8. Electrical specifications at 25°C.

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