Procurement Notes

Verify the current lifecycle status before procurement, as official records indicate this part number may be discontinued. Confirm compatibility with existing board layouts due to potential header design revisions in newer product families. Request updated qualification data from the manufacturer to ensure compliance with current assembly standards and traceability guidelines prior to finalizing orders.

Selection Notes

Select this component specifically for AUI Ethernet LAN interfaces requiring encapsulated pulse transformers. Ensure the design accommodates the 16SOIC surface mount footprint and the specified 11.43mm x 6.73mm x 5.46mm envelope. Verify that the operating environment remains within the 0°C to 70°C thermal limits and that the 100µH inductance meets the circuit requirements.

Part Context

This component belongs to the Pulse Transformers category under Pulse Electronics' portfolio. It serves as a specialized magnetic solution for network connectivity, distinct from general-purpose power inductors or standard audio signal transformers. The encapsulated type offers robust protection for sensitive data lines in compact electronic assemblies.

Replacement Considerations
