Miniature Flyback Transformers for PoE  
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.
