Procurement Notes
Verify the specific ordering suffix to ensure correct packaging format, as variants exist for tape-and-reel or tube quantities. Confirm RoHS compliance status and lead times directly with authorized distributors. Cross-reference the manufacturer part number against official datasheets to validate pinout compatibility and thermal requirements before finalizing procurement orders.
Selection Notes
Select this component for designs requiring standard 1:1 coupling ratios for both transmitter and receiver paths. Ensure the application does not require Power over Ethernet capabilities, as this model is specified for NonPoE use cases. Verify that the surface mount footprint matches the PCB layout constraints defined by the 16.51mm x 9.14mm dimensions.
Part Context
This component belongs to Pulse Electronics' LAN transformer portfolio, specifically engineered for copper-based Ethernet connectivity. It serves as a critical interface between the MAC layer and the physical medium, ensuring signal integrity across varying network speeds. The design adheres to industry standards for electromagnetic interference reduction and channel balance.
