Procurement Notes

Verify the specific datasheet version for the ALAN110001-4J61DT prior to ordering, as manufacturer specifications may undergo revisions. Confirm that the surface mount footprint matches the target PCB design, specifically checking the 15.49mm by 13.95mm dimensions and 5.72mm height constraints. Ensure compatibility with the required operating temperature range of -40°C to +85°C for the intended application environment.

Selection Notes

Select this component when designing systems that require combined data and power delivery over standard Ethernet cabling. The 350 µH inductance value is critical for maintaining signal quality at gigabit speeds. Consider the physical size and thermal performance if space is limited or if the device will operate near the upper temperature limit of 85°C.

Part Context

This part belongs to Abracon's LAN transformer series, which focuses on providing reliable isolation and signal conditioning for network interfaces. These components are essential for protecting downstream electronics from voltage spikes and ensuring compliant data transmission across twisted-pair cables in both commercial and industrial settings.

Replacement Considerations

Direct substitutes include other 10/100/1000BASE-T PoE transformers with similar 350 µH inductance and compatible pin configurations. Verify that any replacement maintains the same 1CT:1CT turns ratio and meets the required isolation voltage standards for the specific application.
