H5009NL

Overview

The H5009NL is a surface-mount LAN transformer module manufactured by Pulse Electronics, designed for Gigabit Ethernet applications. It supports 10/100/1000 Base-T standards and features a single-port configuration with a 1:1 turns ratio. The component utilizes a gull-wing SMD package (SOP24) and operates within a temperature range of 0°C to +70°C. Key electrical specifications include an inductance of 350µH and a maximum DC resistance of 650mΩ. It is non-PoE compliant and offers unshielded construction.

Feature Summary

• Supports 10/100/1000 Base-T Gigabit Ethernet data transmission
• Single-port architecture with integrated isolation
• Surface-mount design compatible with automated assembly processes

Applications

• Gigabit Ethernet network interface cards
• Broadband routers and switches
• Network infrastructure equipment

Procurement Notes

Verify RoHS compliance status through official manufacturer documentation prior to integration. Confirm that the specific ordering suffix matches the required packaging format, as variations may exist between tube and reel configurations. Ensure the selected variant aligns with the non-PoE requirement of the target circuit design.

Selection Notes

Select this component for designs requiring a single-port Gigabit solution without Power over Ethernet capabilities. The SOP24 footprint accommodates standard surface-mount assembly lines. Verify thermal performance within the specified 0°C to +70°C operating range to ensure reliability under intended environmental conditions.

Part Context

This part belongs to the Pulse Electronics LAN Transformers category, specifically engineered for high-speed data interface isolation. It serves as a critical passive component in maintaining signal integrity and electrical safety in modern networking hardware, distinguishing itself from PoE-enabled variants through its simplified internal winding structure.

Replacement Considerations

The H5008NLT is a documented substitute offering dual-port functionality in a similar surface-mount form factor. Verify pin compatibility and port requirements before substitution, as the replacement provides two ports instead of one.
