1. When ordering, please specify packaging code:
POE300F-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 250 kHz, 0.7 Vrms, 0 Adc.
3. Peak primary current drawn at minimum input voltage.
4. DCR is with the windings connected in parallel.
5. Leakage inductance is for the primary winding with the secondary
windings shorted.
6. Turns ratio is with the primary and the secondary windings connected in
parallel.
7. Output is with the secondary windings connected in parallel. Output of
the auxiliary winding is 12 V
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
