HX1224CNL

Overview

The HX1224CNL is a single-port, surface-mount Ethernet transformer module designed for 10/100BASE-T applications. It features a 1:1 turns ratio with primary DC resistance of 0.6 Ohms and secondary DC resistance of 1.2 Ohms. The component utilizes a gull-wing SMD package with dimensions of 13.64mm x 14.48mm x 6.22mm. It operates within a temperature range of -40°C to 85°C and provides 4kV isolation. This non-PoE compliant unit meets IEEE 802.3 specifications for LAN connectivity.

Feature Summary

• Surface-mount construction optimized for automated PCB assembly processes
• Integrated common mode choke functionality for signal integrity
• High voltage isolation capability for safety compliance
• RoHS compliant manufacturing standards

Applications

• 10/100BASE-T Ethernet network interfaces
• Single-port LAN connectivity modules
• Medical electronic equipment requiring isolation
• Industrial communication devices

Procurement Notes

Verify the complete part number including suffixes against official Pulse Electronics documentation to ensure correct pinout and insulation class. Confirm RoHS status and specific packaging requirements such as reel size or tape-and-reel specifications prior to ordering. Cross-reference datasheet revision dates to validate current electrical characteristics and mechanical drawings.

Selection Notes

Select this component for designs requiring non-Power over Ethernet solutions in compact form factors. Ensure the application does not exceed the specified 85°C operating temperature limit. Verify that the 4kV isolation rating aligns with system safety requirements. Confirm compatibility with standard 10/100Mbps data rates rather than Gigabit speeds.

Part Context

This module belongs to the HX series of LAN transformers from Pulse Electronics. It serves as a critical interface between the Ethernet PHY chip and the RJ45 connector. The series supports various isolation voltages and pin configurations for different industrial and commercial networking standards.

Replacement Considerations

Check for direct substitutes within the HX series offering identical 1:1 ratios and 4kV isolation. Verify mechanical footprint compatibility with existing PCB layouts. Ensure replacement parts maintain the same gull-wing terminal configuration and thermal performance ratings.
