Inductance is measured at 150 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. 4. Leakage inductance is for the primary windings connected in parallel and with the secondary winding shorted. 5. Turns ratios are with the primary windings connected in parallel. 6. Output is for the secondary winding. Output of the bias winding output is 12 V, 20 mA. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
