Procurement Notes

Verify the specific suffix designation against official datasheets to confirm exact mechanical and electrical characteristics, as variations may exist within the product family. Confirm moisture sensitivity level handling requirements during storage and reflow soldering processes. Ensure compliance with relevant environmental directives such as RoHS and REACH status before integration into final assemblies.

Selection Notes

Select this component when designing single-port Gigabit Ethernet solutions requiring compact surface mount transformers. Consider the 1.5 kV insulation rating for isolation requirements and the 0°C to +70°C temperature range for standard commercial environments. Verify footprint compatibility with PCB layout constraints given the 17.53 mm x 12.2 mm dimensions.
