Procurement Notes

Verify the specific suffix configuration against official documentation, as variations such as FXNL or FT may exist with different electrical characteristics or packaging. Confirm RoHS compliance status directly with the manufacturer, as some variants in this series are noted as non-compliant. Ensure the selected part matches the required insulation voltage and current ratings for the target application circuit design.

Selection Notes

Select this component for high-density PCB layouts requiring robust signal integrity in Gigabit Ethernet environments. The SMD-50P footprint allows for compact board designs while maintaining necessary isolation properties. Consider thermal management requirements given the wide operating temperature range and potential power dissipation in high-speed data lines.
