Magnetics for PoE/PoE+ Applications

Coilcraft Magnetics for PoE and PoE+ Applications are flyback transformers developed for Powered Devices (PD) in IEEE 802.3af compliant Power-over-Ethernet (PoE) applications. The transformers feature a 36V to 72V input voltage range, 250kHz switching frequency, and a 1500V_rms isolation. The transformers are also RoHS compliant and 260°C compatible with tin-silver over tin over nickel over phosphorous bronze terminations. The PoE300F components are designed to meet IEEE 802.3at-2009 standard and developed specifically for POE+ flyback applications up to 30W.
