H5019EFNL

Overview

The H5019EFNL is a single-port LAN transformer module manufactured by Pulse Electronics, designed for 1000Base-T applications. It features surface mount (SMD) termination and operates within a temperature range of 0°C to +70°C. The component has physical dimensions of 19.81mm in length, 19.05mm in width, and a maximum seated height of 2.54mm. It utilizes a 1CT:1 turns ratio for both transmitter and receiver channels and includes an integrated common mode choke with 350µH inductance. The unit is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Integrated common mode choke functionality combined with LAN isolation
• Surface mount construction optimized for automated assembly processes
• Designed specifically for Gigabit Ethernet (1000Base-T) signal transmission

Applications

• Gigabit Ethernet network interface cards
• Ethernet switch port interfaces
• Industrial networking equipment requiring non-PoE solutions

Procurement Notes

Verify the specific packaging suffix when ordering, as tape and reel variants require a 'T' designation appended to the base part number. Confirm current availability status, as this component may be subject to discontinuation or lifecycle changes. Ensure compatibility with existing PCB footprints measuring 19.81mm by 19.05mm before finalizing procurement decisions.

Selection Notes

Select this module for designs requiring a compact, single-port solution for Gigabit Ethernet without Power over Ethernet capabilities. The integrated common mode choke simplifies the schematic by reducing external component count. Verify that the operating temperature range of 0°C to +70°C meets the environmental requirements of the target application.

Part Context

This component belongs to Pulse Electronics' portfolio of audio and signal transformers, specifically categorized under LAN discrete modules.
