100Base-TX network connections

Procurement Notes

Verify the specific suffix against official documentation, as ordering codes may indicate variations in packaging or tape-and-reel configurations that do not alter the core electrical function. Confirm RoHS compliance status through the manufacturer's current datasheet. Ensure the selected variant matches the required channel count and inductance specifications for the target circuit design before finalizing procurement.

Selection Notes

Select this component for designs requiring robust common mode noise suppression in automotive Ethernet links. The 350 µH inductance value supports 10/100 Base-T signaling integrity. Verify that the SMT package dimensions fit the PCB footprint constraints. Ensure the operating temperature range meets the environmental requirements of the installation site.

Part Context

This part belongs to Pulse Electronics' BMS series of automotive communication magnetics. It serves as a critical interface component for vehicle networking, bridging the gap between physical layer transceivers and the cable harness. The series emphasizes reliability and compact form factors suitable for space-constrained automotive electronics.
