When ordering, please specify packaging code: POE30P-12LD Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape. B = Less than full reel. 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, 0.1 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 3 and 4 with all other pins shorted. 6. Turns ratio is with the secondary windings connected in parallel. 7. Output of the secondary is with the windings connected in parallel. Bias winding output is 12 V, 20 mA. 8. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
