1. Inductance is measured at 100 kHz, 0.1 Vrms.  
2. Peak primary current drawn at minimum input voltage.  
3. DCR for the primary is with the windings connected in parallel.  
5. Turns ratios are with the primary windings connected in parallel.  
6. Electrical specifications at 25°C.  
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.  
4. Leakage inductance is for both windings of the primary with the  
secondary windings shorted.
