H5019NL

Overview

The H5019NL is a LAN transformer module designed for 1000Base-T applications. It features a single-port configuration with surface mount (SMD) termination. The component operates within a frequency range of 1 MHz to 100 MHz and provides an insulation voltage of 1.5 kV. It supports non-PoE signaling and functions at temperatures between 0°C and +70°C.

Feature Summary

• Supports Gigabit Ethernet data transmission standards
• Provides electrical isolation for signal integrity
• Designed for compact surface mount integration

Applications

• 1000Base-T network interface circuits
• Gigabit Ethernet port implementations
• Network equipment signal conditioning

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Pulse Electronics or authorized distributors before procurement. Confirm that the non-PoE specification aligns with the target circuit design requirements, as power-over-Ethernet variants exist within similar product families. Ensure the SMD footprint matches the intended PCB layout constraints.

Selection Notes

Select this component when a single-port solution for Gigabit Ethernet is required without Power over Ethernet capabilities. Consider the thermal operating range of 0°C to +70°C against environmental conditions. Evaluate the physical dimensions and SMD mounting style for compatibility with the assembly process and available board space compared to dual-port alternatives.

Part Context

This part belongs to the Pulse Electronics LAN Transformers category, specifically engineered for high-speed digital signal coupling in networking hardware. It serves as a critical interface component between the PHY transceiver and the external RJ45 connector, ensuring impedance matching and common-mode noise rejection for reliable data communication.

Replacement Considerations

H5012NL is a dual-port variant; verify port count requirements. H5004NLT is a single-port alternative; confirm PoE compatibility differences.
