HX2326FNL

Overview

The HX2326FNL is a single-port LAN transformer module designed for 100Base-TX PoE+ applications. It features surface-mount (SMD) termination and operates within a frequency range of 1 MHz to 125 MHz. Key electrical parameters include an inductance of 350 µH and an insulation voltage of 1.5 kV. The component supports a primary-to-secondary turns ratio of 1:1/1:1 with 16 terminals in a gull-wing configuration. Physical dimensions are 12.7 mm in length, 9.09 mm in width, and 5.99 mm in height. It functions without shielding and withstands operating temperatures from -40°C to +85°C.

Feature Summary

• Supports Power over Ethernet Plus (PoE+) standards for integrated power and data transmission
• Provides galvanic isolation with high insulation voltage capability
• Optimized for 100Base-TX network interfaces with dedicated transmitter and receiver channels

Applications

• 100Base-TX Ethernet network interface circuits
• PoE+ powered devices requiring single-port connectivity
• Servers and networking equipment utilizing LAN transformers

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be marked as Not Recommended for New Designs (NRND). Confirm that the SMD package dimensions and pinout align with the target PCB layout. Ensure compliance with RoHS directives if required by the final assembly specifications. Check for available substitute part numbers if production continuity is a priority.

Selection Notes

Select this component when designing for 100Base-TX environments requiring PoE+ support. The unshielded design suits applications where external EMI protection is managed separately. Verify that the 1.5 kV insulation rating meets safety requirements. Consider the NRND status for long-term supply chain stability and evaluate alternative models if new designs are planned.
