Pulse Transformers Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly from Würth Elektronik before procurement. Confirm that the surface mount footprint matches the PCB layout design requirements. Ensure the operating temperature range aligns with the final product's environmental specifications. Cross-reference the part number to avoid confusion with similar WE-LAN series components.
Pulse Transformers Selection Notes
Select this component when designing systems requiring 10/100 Base-T connectivity with AutoMDIX support. Consider the surface mount package constraints and thermal performance limits up to 105°C. Evaluate the need for integrated magnetics versus discrete solutions based on space and cost targets. Verify compatibility with the target Ethernet PHY controller specifications.
Pulse Transformers Part Context
This part belongs to the Würth Elektronik WE-LAN series, which specializes in LAN transformers and modular jack connectors. The series offers various configurations for different Ethernet speeds and mounting types.
