HX5008FNLT

Overview

The HX5008FNLT is a single-channel LAN pulse transformer module manufactured by Pulse Electronics. Designed for surface-mount technology, it supports 10/100/1000 Base-T Ethernet standards without Power over Ethernet (PoE) functionality. The component features a primary-to-secondary turns ratio of 1CT:1 for both transmitter and receiver circuits. It has an inductance of 325µH and operates within a temperature range of -40°C to +85°C. Physical dimensions are approximately 13.16mm x 17.86mm with a maximum height of 6.12mm.

Feature Summary

• Supports Gigabit Ethernet data transmission for 10/100/1000 Base-T applications
• Integrated transmitter and receiver isolation in a single compact module
• Surface-mount construction optimized for automated PCB assembly processes

Applications

• Gigabit Ethernet network interface cards
• Industrial communication equipment requiring isolated signal transmission
• Consumer networking hardware such as routers and switches

Procurement Notes

Verify the specific suffix 'FNLT' to confirm surface-mount tape-and-reel packaging and RoHS compliance status. Ensure design compatibility with non-PoE circuit topologies, as this unit lacks integrated PoE filtering components required for powered devices. Cross-reference manufacturer datasheets for updated moisture sensitivity levels and reflow soldering profiles prior to production integration.

Selection Notes

Select this component when designing systems requiring isolated Gigabit Ethernet signals without power delivery capabilities. The 325µH inductance value suits standard differential line impedance requirements. Consider the physical footprint and thermal operating range against available board space and environmental conditions. Alternative modules may be necessary if PoE support or shielded configurations are required for the specific application environment.

Part Context

This part belongs to the HX series of LAN transformers from Pulse Electronics. These modules are engineered to provide galvanic isolation between the PHY chip and the RJ45 connector. The series typically includes variants for different Ethernet speeds and PoE requirements, serving as critical components for maintaining signal integrity and protecting downstream electronics from voltage surges.

Replacement Considerations

HX5008FNL is a tube-packaged variant of the same electrical specification. HXB5008HLT is a different module type with distinct parameters. Verify pinout compatibility and mechanical dimensions before substituting with other manufacturers' equivalents.
