1. Inductance is for the primary, measured on Agilent/HP 4284A at
200 kHz, 0.5 Vrms, 0 Adc.
2. Leakage Inductance is for the primary, measured at 100 kHz,
0.1 Vrms, 0 Adc with secondary pins shorted.
3. Volt-time product is based on primary turns and 3000 gauss.
4. Output of the aux winding is 12 V.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
