HX1344NLT

Overview

The HX1344NLT is a LAN transformer module manufactured by Pulse Electronics, designed for SMD/SMT mounting. It supports 100Base-TX applications with a frequency range of 100 kHz to 100 MHz and an inductance of 350 uH. The component features a 1:1:1:1 winding configuration, providing electrical isolation with a maximum insulation voltage of 1.5 kV. It has a maximum DC resistance of 650 mOhms and operates within a temperature range of -40°C to +85°C. The module is unshielded, measures 16.002 mm in length, 9.53 mm in width, and 5.715 mm in height, and complies with RoHS standards.

Feature Summary

• Provides electrical circuit isolation meeting IEEE 802.3 standards for signal integrity
• Optimized for major LAN transceivers with peak reflow temperature rating of +245°C
• Features a 1:1:1:1 winding configuration for dedicated transmit and receive channels

Applications

• 100Base-TX network interfaces
• Non-PoE LAN connections
• Ethernet transceiver circuits

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging format, as designations may vary. Ensure compatibility with standard surface mount assembly processes given the +245°C peak reflow rating. Confirm that the unshielded construction aligns with the electromagnetic interference requirements of the target application environment before finalizing procurement.

Selection Notes

Select this component for designs requiring isolated 100Base-TX connectivity without Power over Ethernet capabilities. The 350 uH inductance and 1.5 kV isolation voltage are suitable for standard Ethernet physical layer implementations. Consider the unshielded nature of the module when planning PCB layout to manage potential crosstalk or external interference in dense electronic assemblies.
