SMT PoE Transformer
s
This series of transformers is designed specifically for
PoweredDevices(PD)inIEEE802.3af-compliantPower
over Ethernet (PoE) applications.
They feature interleaved primary and secondary wind-
ings to minimize leakage inductance, and a separate
bias winding. Isolation is 1500 Vrms between the
primary and secondary windings.
Coilcraft’s PoE transformers are available in 6 Watt and
13 Watt output versions for a 250 kHz switching fre-
quency. Input is 36 – 72 Volt and the output of the bias
winding is 12 V, 0.2 A.
Thesepartscanbeorderedwithleadscoatedinlead-free
solder that make them compliant with RoHS standards.
Coilcraft can also custom engineer a transformer to
meet your specific requirements.
Coilcraft Designer’s Kit C172 contains samples of all parts.

tape (200 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.

When ordering a RoHS-compliant part, add an “L” before the packaging
code: e.g. POE13F-12LD
2. Inductance is measured at 250 kHz, 0.3 Vrms.
3. Peak primary current drawn at minimum input voltage.
4. Leakage inductance is for the primary winding with the secondary
winding shorted.
