Procurement Notes

Verify the specific datasheet version, as Mentech product specifications may undergo revisions. Confirm that the required operating temperature range of 0°C to +70°C aligns with your system's thermal design. Ensure the surface mount footprint matches your PCB layout constraints. Check for any specific ordering suffixes that might indicate packaging variations or updated compliance certifications before finalizing procurement orders.

Selection Notes

Select this component when a compact, single-port solution for 10/100 Base-T networks is required. The integrated RJ45 connector reduces bill-of-materials complexity compared to discrete transformer and jack combinations. Consider the 350µH minimum inductance for standard Ethernet signaling requirements. Evaluate the surface mount form factor against available board space and automated assembly capabilities.
