1. When ordering, please specify packaging code:

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

3. Peak primary current drawn at minimum input voltage.

4. Leakage inductance is for the primary winding with the secondary

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

6. Output of the secondary is with the windings connected in parallel. Bias

7. Electrical specifications at 25°C.

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