Procurement Notes

Verify the specific suffix ET against the manufacturer's current datasheet to confirm active status and pinout configuration. Ensure the operating temperature range aligns with the system requirements, as industrial variants may differ. Cross-reference the isolation voltage rating with safety regulations applicable to the end product deployment environment.

Selection Notes

Select this component when a combined LAN transformer and common mode choke solution is required for space-constrained designs. The dual-channel architecture supports differential signaling necessary for Ethernet data transmission. Verify that the surface mount footprint matches the PCB layout constraints and thermal management strategy of the target application.

Part Context
