Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with Pulse Electronics or authorized distributors before procurement. Confirm that the ordering suffix matches the required packaging format, such as cut tape or reel quantities. Ensure the component meets the thermal requirements of the target application environment. Cross-reference the manufacturer part number with official catalogs to avoid counterfeit components. Check for any recent product change notifications that may affect specifications.
Selection Notes
Select the HX1098NLT when designing 100 Mbps Ethernet interfaces that require integrated PoE capabilities. This module is suitable for applications needing high isolation voltage and broad frequency response. Consider the physical dimensions and mounting style for PCB layout constraints. Evaluate the operating temperature range against environmental conditions. Compare with other HX series variants if different channel counts or impedance values are required.
Part Context
The HX1098NLT belongs to the HX series of LAN discrete transformer modules from Pulse Electronics. These modules are engineered to provide reliable isolation and signal integrity for various LAN transceivers. The series generally supports frequencies up to 100 MHz and offers options for PoE integration. This specific model addresses the needs of 100BaseTX networks with power delivery requirements.
Replacement Considerations
Consult official Pulse Electronics documentation for verified substitute part numbers. Ensure any replacement maintains identical electrical parameters, including inductance, isolation voltage, and PoE compatibility. Verify mechanical fit and pinout compatibility before substitution.
