HX5004ENLT

Overview

The HX5004ENLT is a surface-mount LAN pulse transformer manufactured by Pulse Electronics, designed for 10/100/1000 Base-T Ethernet applications. It features a single-channel configuration with a 1:1 turns ratio and supports frequencies up to 125 MHz. Key electrical parameters include an inductance of 350 µH, a maximum DC resistance of 650 mOhms, and an isolation voltage of 1.5 kV. The component operates within a temperature range of -40°C to +85°C and measures 17.5 mm in length, 12.2 mm in width, and 5.72 mm in height.

Feature Summary

• Provides balanced signal transmission with a 1:1 turns ratio for transmitter and receiver channels.
• Ensures enhanced safety through 1500 Vrms isolation capability between primary and secondary circuits.
• Supports high-speed data integrity with low insertion loss characteristics suitable for Gigabit Ethernet.

Applications

• 10/100Base-T Ethernet network interfaces
• 1000Base-T Gigabit Ethernet transceivers
• LAN port signal conditioning modules

Procurement Notes

Verify the specific suffix ENLT against the official datasheet to confirm surface-mount tape-and-reel packaging and non-potting status. Ensure compatibility with automated pick-and-place equipment due to SMD form factor. Cross-reference manufacturer part numbers with distributor catalogs to avoid confusion with similar HM series variants that may differ in thermal or mechanical specifications.

Selection Notes

Select this component when designing compact Ethernet PHY interfaces requiring surface-mount integration. Verify that the 12.2 mm width fits within the PCB footprint constraints. Confirm that the 1.5 kV isolation rating meets system safety requirements. Check that the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the target application.
