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 400 kHz, 0.4 Vrms, 0 Adc. 3. Ipk is peak primary current drawn at minimum input voltage. 4. DCR for the secondary is per winding. 5. Leakage inductance measured between pins 2 and 3 with all secondary pins shorted. 6. Turns ratio is with the secondary windings connected in parallel. 7. Output is with the secondary windings connected in parallel. 8. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
