HX1260FNLT

Overview

The HX1260FNLT is a single-port LAN pulse transformer module manufactured by Pulse Electronics, designed for surface-mount applications. It supports 10/100 Base-T Ethernet standards and includes Power over Ethernet (PoE) capability. The component features an inductance of 350 µH with a minimum DC resistance of 0.65 Ohms. It operates within a frequency range of 1 MHz to 125 MHz and withstands an isolation voltage of 1.5 kV. The physical dimensions are 12.7 mm in length, 9.09 mm in width, and 5.99 mm in height. The unit functions across a temperature range from -40°C to +85°C.

Feature Summary

• Supports 10/100 Base-T Ethernet data transmission with integrated PoE functionality
• Single-channel configuration optimized for compact surface-mount layouts
• Provides high electrical isolation via 1.5 kV dielectric strength rating

Applications

• 10/100 Base-T network interface cards
• Power over Ethernet enabled hubs and switches
• Industrial Ethernet communication modules

Procurement Notes

Verify the specific suffix against official datasheets to confirm PoE support and pinout compatibility. Ensure the selected variant matches the required thermal operating range and insulation voltage specifications for the target application environment.

Selection Notes

Select this component when designing circuits requiring combined data and power delivery over standard twisted-pair cabling. Consider the unshielded construction and specific footprint requirements during PCB layout planning to ensure proper signal integrity and mechanical fit.

Part Context

This part belongs to the HX series of LAN transformers from Pulse Electronics. It serves as a magnetic coupling solution for Ethernet connectivity, bridging the PHY chip to the RJ45 connector while providing necessary impedance matching and common-mode noise rejection.

Replacement Considerations

HX1260NLT is a documented non-PoE alternative within the same product family.
