H5008NL

Overview

The H5008NL is a single-port LAN pulse transformer module from Pulse Electronics, designed for Gigabit Ethernet applications. It supports 10/100/1000 Base-T standards without Power over Ethernet (PoE) functionality. The component features an inductance of 350 µH and a center-tap to center-tap ratio of 1:1 for both transmitter and receiver circuits. It utilizes a surface-mount device (SMD) package with dimensions of approximately 18.87 mm x 13.67 mm x 5.87 mm. The unit provides 1.5 kV isolation voltage and operates within a temperature range of 0°C to 70°C.

Feature Summary

• Supports 10/100/1000 Base-T data transmission standards
• Provides galvanic isolation via integrated magnetic module design
• Optimized for surface-mount assembly processes

Applications

• Gigabit Ethernet network interface cards
• Ethernet switch port interfaces
• Network adapter circuitry

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm PoE compatibility, as variants exist with identical base part numbers but different electrical characteristics. Ensure the selected component matches the non-PoE requirement if power delivery is not needed. Cross-reference manufacturer documentation for updated RoHS compliance status and moisture sensitivity levels prior to final procurement decisions.

Selection Notes

Select this component for designs requiring isolated Gigabit Ethernet connectivity without PoE power injection capabilities. Confirm that the 350 µH inductance value aligns with the specific PHY transceiver requirements of the target system. Evaluate the physical footprint constraints against the SMD package dimensions to ensure compatibility with the printed circuit board layout and automated placement equipment specifications.

Part Context

This component belongs to the Pulse Electronics LAN transformer portfolio, specifically engineered for high-speed digital signal integrity in networking hardware. It serves as a critical interface between the Ethernet MAC/PHY layer and the physical medium, ensuring signal coupling and noise rejection. The module integrates primary and secondary windings into a compact form factor suitable for modern electronic device miniaturization trends.

Replacement Considerations

The H5008NLT is a parameter-equivalent variant offered by the same manufacturer, differing primarily in packaging format rather than electrical performance. Verify pinout compatibility and mechanical tolerances before substituting components in existing designs.
