HX5004ENL

Overview

The HX5004ENL is a single-port LAN transformer module from Pulse Electronics, designed for 1000Base-T applications. It features surface mount (SMD) termination and operates within a frequency range of 1 MHz to 100 MHz. The component has an inductance of 350 uH and provides 1.5 kV isolation voltage. It supports a DC resistance of 0.65 Ohms for both primary and secondary windings. The module functions within a temperature range of -40°C to +85°C. Physical dimensions are 17.5 mm in length, 12.2 mm in width, and 5.72 mm in height. It is unshielded and suitable for non-PoE Ethernet networks.

Feature Summary

• Provides electrical circuit isolation compliant with IEEE 802.3 standards
• Optimized for major LAN transceivers to maintain signal integrity
• Supports peak reflow temperature rating of +245°C

Applications

• 1000Base-T Ethernet network interfaces
• Non-PoE LAN transceiver circuits
• Signal transmission modules requiring 1.5 kV isolation

Procurement Notes

Verify the specific datasheet version for the HX5004ENL to confirm RoHS compliance details and exact physical tolerances. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range. Confirm that the non-PoE designation aligns with the power requirements of the target Ethernet port design. Cross-reference the 17.5 mm x 12.2 mm footprint with PCB layout constraints before finalizing procurement.

Selection Notes

Select this component for designs requiring a single-port, non-Powered-over-Ethernet solution for Gigabit Ethernet. The HX5004ENL is appropriate where standard 350 uH inductance and 1.5 kV isolation are sufficient. Consider the unshielded nature of the module when assessing electromagnetic interference requirements. This part is distinct from automotive-grade alternatives like the HM5004ENL, which offers higher temperature ratings and AEC-Q200 qualification.
