When ordering, please specify packaging code: POE120PL-24LD Packaging: Blank In trays, 36 per tray D = Optional tape and reel (additional cost), 13 machine-ready reel. EIA-481 embossed plastic tape. See tape and reel specifications on page 2. Factory order only, not stocked. B = Optional tape and reel (additional cost), less than full reel. In tape, but not machine ready. To have a leader and trailer added ( 25 charge), use code letter D instead. Factory order only, not stocked. 2. Inductance is for the primary, measured at 200 kHz, 0.5 Vrms, 0 Adc. 3. Leakage inductance is for the primary and is measured with the secondary winding shorted. 4. Electrical specifications at 25C. Refer to Doc 362 Soldering Surface Mount Components before soldering.
