Procurement Notes

Verify that the specific suffix 'I' matches the required RoHS compliance status and lead-free soldering specifications for your manufacturing process. Confirm that the dual-port pinout aligns with the target PCB layout, as Allied Components International may offer variant suffixes for different isolation or packaging requirements. Ensure the surface mount footprint corresponds exactly to the 27.80mm x 12.20mm dimensions specified in the official datasheet to prevent assembly errors.

Selection Notes

Select this component when designing systems requiring integrated Gigabit magnetics with built-in transient protection. The dual-port architecture simplifies board space compared to discrete solutions. Consider the surface mount profile for high-volume production environments. Verify that the integrated ESD protection levels meet the electromagnetic compatibility requirements of the end application without necessitating external protective components.

Part Context

This part belongs to the AGSC series of LAN transformers from Allied Components International. The series focuses on providing complete magnetic solutions for Ethernet connectivity.
