Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the surface mount package dimensions and pinout align with the target PCB layout. Ensure that the operating temperature range and isolation voltage requirements of the application are met by this component's specifications. Cross-reference the part number to avoid confusion with similar models in the Pulse Electronics portfolio.

Selection Notes

Select the H1100FNLT for designs requiring 10G Base-T connectivity with integrated magnetics. Consider its 1.5 kV isolation voltage and 350 µH inductance for signal integrity needs. Evaluate the SMD package size against available board space. Compare performance metrics against other LAN transformers if multiple ports or different speeds are required. Ensure compatibility with the intended transceiver ICs for optimal signal transmission.

Part Context

This component belongs to the Pulse Electronics LAN discrete transformer modules series. These modules are engineered to provide essential isolation and signal conditioning for Ethernet networks. The H1100FNLT specifically targets 10G Base-T applications, distinguishing it from lower-speed variants like 100Base-TX or 1000Base-T. It represents a solution for integrating magnetics directly into high-density PCB designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult official cross-reference guides or contact the manufacturer for verified alternatives. Do not assume functional equivalence with other LAN transformers without verifying electrical parameters and pinouts.
