HX5008NLST

Overview

The HX5008NLST is a single-port LAN transformer module from Pulse Electronics, designed for 1000BASE-T applications. It features surface-mount technology (SMD/SMT) termination and operates within a frequency range of 1 MHz to 100 MHz. The component provides an inductance of 325 µH and supports Power over Ethernet (PoE). It offers an isolation voltage of 1.5 kV and functions reliably between -40°C and +85°C. The physical dimensions are 13.64 mm in length, 13.64 mm in width, and 5.72 mm in height.

Feature Summary

• Provides electrical circuit isolation compliant with IEEE 802.3 standards for signal integrity
• Optimized for major LAN transceivers supporting 10/100/1000 Base-T data rates
• Supports Power over Ethernet (PoE) functionality in a compact surface-mount package

Applications

• 1000BASE-T network interface cards
• Ethernet switches and hubs
• Network infrastructure equipment requiring PoE support

Procurement Notes

Verify the specific suffix 'ST' against official datasheets to confirm tape-and-reel packaging versus tube variants. Ensure compatibility with peak reflow temperature ratings of +245°C during assembly. Cross-reference manufacturer part numbers to distinguish between PoE-enabled and non-PoE versions within the HX series.

Selection Notes

Select this component for designs requiring integrated isolation and PoE capabilities in a single-port configuration. Consider the 1.5 kV isolation voltage for safety compliance. Verify footprint compatibility with the specified 13.64 x 13.64 mm dimensions and ensure thermal management aligns with the -40°C to +85°C operating range.

Part Context

This part belongs to the HX series of LAN discrete transformer modules from Pulse Electronics. These modules are engineered to maintain signal integrity while providing necessary galvanic isolation for Ethernet applications. The series typically includes variants optimized for different power delivery requirements and mounting styles.

Replacement Considerations

HX5008NL: Non-POE variant with similar specifications but lacks power delivery support.
