HX2326NLT

Overview

The HX2326NLT is a single-port LAN pulse transformer module from Pulse Electronics, designed for 100Base-TX PoE+ applications. It features surface mount termination and operates within a frequency range of 1 MHz to 125 MHz. The component has a primary coil impedance of 100 Ohms and an insulation voltage rating of 1.5 kV. Physical dimensions are 12.7 mm in length, 9.09 mm in width, and 5.99 mm in height. It supports a working temperature range from -40°C to +85°C and utilizes a 1CT:1CT turns ratio.

Feature Summary

• Supports Power over Ethernet Plus (PoE+) standards for simultaneous data and power transmission
• Provides electrical isolation with a 1.5 kV insulation voltage rating
• Optimized for 100Base-TX Ethernet signal integrity and noise reduction

Applications

• 100Base-TX PoE+ network interface cards
• Ethernet switches with PoE+ capabilities
• Access points supporting IEEE 802.3at standards

Procurement Notes

Verify the specific suffix and marking against official datasheets to ensure compatibility with PoE+ requirements. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for recent production change notices that may affect pinout or material composition. Ensure storage conditions maintain component integrity before soldering.

Selection Notes

Select this component when designing systems requiring integrated PoE+ support without external circuitry. The single-port configuration simplifies layout for standard Ethernet connections. Consider the thermal performance within the specified operating temperature range. Verify footprint compatibility with existing PCB designs due to specific dimensional constraints.
