Flyback and forward transformers for Power over Ethernet up to 72 watts, operating with 33-57 V input, designed for automotive applications under AEC-Q200 Grade 1 (-40°C to +125°C). The part is packaged in a surface-mount tape and reel format per EIA-481, with dimensions of 14.99 mm width, 17.7 mm length, and 10 mm height. It has a primary inductance of 100 µH ±15%, leakage inductance of 0.40 µH, and maximum DCR of 6.5 mΩ for each secondary. The turns ratio is 1:0.167:0.167:0.50, delivering a 3.3 V, 8.0 A output per secondary and a 10 V, 50 mA auxiliary output. Core material is ferrite, with tin-silver-copper over tin over nickel over phosphor bronze terminations. The component is RoHS compliant, halogen free, rated for up to 165°C maximum part temperature, and withstands three reflow cycles at 260°C. Isolation is 1500 Vrms between primary/auxiliary and secondaries, with 500 Vrms between primary and auxiliary.
