When ordering, please specify packaging code: POE600F-50LD Packaging:D =13″ machine-ready reel. EIA-481 embossed plastic tape (175 parts per full reel). 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 200 kHz, 0.1 Vrms, 0 Adc. 3. DCR for the primary and the secondary is measured with the windings connected in parallel. 4. Leakage inductance is for the primary and is measured with all secondary windings shorted. 5. Turns ratio is with the primary windings and the secondary windings connected in parallel. 6. Output is with the secondary windings connected in parallel. 7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
