In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. Dot above pin1 (A) 1.5 1.5 voltage (V) 4.5 – 8.5 8.5 – 12.0 2. Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc. 3.Ipk is peak primary current drawn at minimum input voltage. 4. Leakage inductance measured between pins 1 and 3 with pins 4 and 6 shorted. 5. Operating temperature range –40°C to +85°C. 6. Electrical specifications at 25°C.
