HX1234NL

Overview

The HX1234NL is a surface mount Ethernet LAN transformer designed for 10/100 Base-TX applications. It features a four-port configuration with a 1:1 turns ratio and a primary inductance of 350 µH. The component provides high-voltage isolation with a minimum hipot rating of 4 kVrms. It is RoHS compliant and suitable for non-PoE signal transmission in data communication interfaces.

Feature Summary

• Four-port architecture supporting 10/100 Base-TX standards
• High voltage isolation capability for signal integrity
• Surface mount package design for automated assembly

Applications

• Ethernet network interface cards
• LAN port connectivity modules
• Data communication equipment requiring 10/100 Mbps speeds

Procurement Notes

Verify the specific datasheet revision to confirm electrical tolerances and pinout configurations before integration. Ensure that the surface mount footprint matches the target PCB layout requirements. Confirm compliance with relevant environmental regulations such as RoHS for the intended market application.

Selection Notes

Select this component for designs requiring isolated signal transformation at 10/100 Mbps speeds. The four-port structure supports multiple differential pairs within a single package. Consider the surface mount form factor for compact board layouts and automated manufacturing processes.

Part Context

This part belongs to Pulse Electronics' Ethernet and LAN transformer series. These components are engineered for data rate compatibility from 1 Gb to 10 Gb, though this specific model targets lower speed base-TX interfaces. They provide essential galvanic isolation between the PHY and the external medium.
