Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Pulse Electronics or authorized distributors before procurement. Confirm that the component meets the required environmental standards for the intended application environment. Ensure compatibility with existing PCB footprints and soldering profiles to maintain signal integrity and mechanical reliability during assembly.

Selection Notes

Select this component specifically for 10Base-T applications requiring non-PoE isolation. Evaluate the 200 uH inductance and 0.6 Ohm resistance against circuit impedance requirements. Consider the surface-mount form factor for space-constrained designs. Validate performance characteristics against industry standards for Ethernet connectivity.

Part Context

This part belongs to Pulse Electronics' portfolio of passive components, specifically within the audio and signal transformers category. It serves as a critical isolation element in legacy Ethernet networking hardware, providing galvanic separation between network lines and internal circuitry while maintaining signal fidelity for 10 Mbps data transmission speeds.

Replacement Considerations

Consult official Pulse Electronics documentation for verified substitute part numbers. Cross-reference specifications such as inductance, resistance, and package dimensions to ensure functional equivalence. Verify that any alternative component maintains the same isolation voltage ratings and frequency response characteristics required for 10Base-T operation.
