1. When ordering, please specify packaging code:
POE120PL-24LD
Packaging: BlankâIn trays, 36 per tray
D = Optional tape and reel (additional cost), 13â³ machine-ready reel. EIA-481 embossed plastic
tape. See tape and reel specifications on page 2.
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.
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 25°C.
Refer to Doc 362 âSoldering Surface Mount Componentsâ before soldering.
