- Telecom signal transformers
Procurement Notes
Verify the specific suffix 'NLT' against official datasheets to confirm surface mount package type and reel packaging configuration. Ensure compatibility with RoHS3 regulations and check moisture sensitivity level classifications prior to assembly. Confirm that the selected variant matches the required non-PoE specification for the target design.
Selection Notes
Select this component for designs requiring single-port 10/100 Ethernet isolation. Verify that the 350 uH inductance and 1.5 kV isolation voltage meet system requirements. Consider the SMD footprint dimensions and thermal characteristics during PCB layout planning to ensure proper integration with compatible LAN transceivers.
Part Context
This part belongs to the HX series of discrete LAN transformer modules from Pulse Electronics. These modules are optimized for major LAN transceivers, providing necessary isolation while maintaining signal quality. The series includes variants for different speeds and port configurations, with this specific model targeting standard Fast Ethernet implementations.
Replacement Considerations
HX1188NL serves as a related variant within the same product family. Verify pinout compatibility and physical dimensions before substitution. Cross-reference datasheets to ensure equivalent electrical parameters and application suitability for the specific design constraints.
