EXPOSED POWER OVER ETHERNET (PoE)
Circuit Conditioning
*e Bourns® model SM51625EL transformer is built to meet IEEE 802.3
specication, by tting in the specied limits dened in the Clause 40.8.3 for
Medium Dependent Interface (MDI) of the IEEE 802.3-2012, thus helps ensure an
application’s compliance to IEEE 802.3-2012.
e schematic shown here illustrates the conditioning of the application and does
not constitute the complete circuit design.
Customers should verify actual device performance in their specic applications.
