1. When ordering, please specify packaging code:
POE60D-12
D
Packaging: D =13
″ machine-ready reel. EIA-481 embossed plastic
tape (400 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 measured at 250 kHz, 0.5 Vrms.
3. Peak primary current drawn at minimum input voltage.
4. Leakage inductance is for the primary winding with the secondary
winding shorted.
5. Designed to remain in continuous mode operation at power levels of
3 Watts and above.
6. Operating temperature range –40°C to +125°C.
7. Electrical specifications at 25°C.

With a footprint roughly 16.5 mm square and with a
height less than 7.5 mm, these are very space-efficient
Power over Ethernet (PoE) transformers. They are
designed for 6 Watt, IEEE 802.3af-compliant applica-
tions for powered devices (PD).
These transformers feature interleaved primary and
secondary windings to minimize leakage inductance,
and a separate bias winding. Isolation is 1500 Vrms
between the primary and secondary windings.
There are versions for continuous and discontinuous
modes of operation, each designed to operate at a
250 kHz switching frequency. Input is 36 – 72 Volts and
the output of the bias winding is 12 V, 0.2 A.
Coilcraft Designer’s Kit C182 contains samples of all parts.
