메모

Output is of the secondary winding frmo pins 11 – 8. Output of the aux winding is 12 V.
Inductance is for the primary, measured on Agilent/HP 4284A at 200 kHz, 0.5 Vrms, 0 Adc with primary windings connected in parallel.
DCR for the primary is measured with the windings connected in parallel. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage Inductance is for the primary, measured at 200 kHz, 0.5 Vrms, 0 Adc with primary windings connected in parallel and all secondary pins shorted.
Volt-time product is based on primary windings connected in parallel.
