Procurement Notes
Verify the specific manufacturer designation, as some sources list Pulse Electronics while others reference Ulse Electronics for this part number. Confirm RoHS compliance status through official documentation before procurement. Ensure the ordering suffix matches the required packaging format, such as Reel or Cut Tape, to align with assembly line requirements. Cross-reference the datasheet for accurate pinout and mechanical dimensions.
Selection Notes
Select this component for single-channel Ethernet applications requiring PoE+ support. The 350 uH inductance and 1.5 kV isolation are critical for signal integrity and safety in 100Base-TX environments. Consider the 12.7 mm x 9.09 mm footprint for PCB layout constraints. The wide operating temperature range suits industrial or outdoor deployments where environmental stability is required.
Part Context
This component belongs to the HX2326 series of datacom transformers from Pulse Electronics. It serves as a signal conditioning element for local area networks, specifically handling differential signaling for Ethernet ports. The module integrates magnetic components to facilitate data transmission and power delivery over twisted-pair cabling.
Replacement Considerations
HX2326FNL is a listed substitute with identical datacom transformer classification and lead time specifications.
