2. Inductance is tested between pins 4 and 3 at 500 kHz, 0.5 Vrms, 0 Adc.  
3. DCR is per winding.  
4. Leakage inductance is for the primary with both windings connected in  
series and with the secondary windings shorted.  
5. Based on Bsat of the core at 25°C and number of turns on winding 4-3.  
6. Calculated output power based on 150 kHz operating frequency.  
Power varies depending on application.  
7. Electrical specifications at 25°C.  
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
