Pulse Transformers Procurement Notes

Verify the specific suffix designation when ordering, as packaging options such as bulk or tape and reel may vary by manufacturer lot. Confirm that the selected variant matches the required insulation voltage and inductance specifications for the target circuit design. Ensure compatibility with the intended LSI transceiver chips before finalizing procurement quantities.

Pulse Transformers Selection Notes

Select this component for designs requiring compact surface mount solutions for Ethernet physical layer interfaces. The 16-pin SOP form factor facilitates automated assembly processes. Consider the 350µH inductance value when matching impedance requirements for the specific transmission line topology. Validate thermal performance within the 70°C operational limit during system integration.
