1. Inductance measured at 100 kHz, 1.1 Vrms, 0 Adc using an Agilent/
HP 4263B impedance analyzer or equivalent.
2. Peak primary current drawn at minimum input voltage.
3. DCR for the secondary is with the windings connected in parallel.
4. Turns ratio is with the secondary windings connected in parallel.
5. Output of the auxiliary winding is 16 V, 20 mA.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
