Bias  
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 wind-  
ings shorted.  
5. Turns ratio is with the secondary windings connected in parallel.  
6. Output of the secondary is with the windings connected in parallel. Bias  
winding output is 10 V.
