In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance is for the primary, measured at 250 kHz, 0.7 Vrms, 0 Adc. 3. Peak primary current drawn at minimum input voltage. 4. DCR is with the windings connected in parallel. 5. Leakage inductance is for the primary winding with the secondary windings shorted. 6. Turns ratio is with the primary and the secondary windings connected in parallel. 7. Output is with the secondary windings connected in parallel. Output of the auxiliary winding is 12 V 8. Electrical specifications at 25C.
