High Power Flyback Transformers for PoE

Coilcraft High Power Flyback Transformers for Power over Ethernet (PoE) are developed for flyback PoE DC/DC PD power converters up to 51W. These transformers are designed to meet IEEE 802.3bt standards and operate at a 250kHz frequency with a 36V to 57V input voltage range. The series offers 1500V_rms, 1-minute isolation (hipot) between primary and auxiliary to secondary. Coilcraft High Power Flyback Transformers are an ideal solution for high-power PoE applications that include smart buildings and IoT.
