H7137NLT

Overview

The H7137NLT is a discrete LAN transformer module designed for 10GBASE-T applications. It features a surface-mount package with dimensions of 17.73mm x 12.19mm and a maximum height of 7.37mm. The component operates within a temperature range of 0°C to 70°C and supports a frequency range of 1 MHz to 400 MHz. It has an inductance of 180 uH and provides a 1:1 turns ratio. The unit is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Discrete five-channel architecture optimized for 10GBASE-T signal integrity
• Surface-mount construction for automated PCB assembly
• Integrated magnetic design supporting high-frequency data transmission

Applications

• 10 Gigabit Ethernet network interface cards
• Server motherboard LAN ports
• Industrial networking equipment requiring 10GBase-T connectivity

Procurement Notes

Verify the specific suffix against official Pulse Electronics documentation, as variations may exist between discrete components and integrated connector modules. Confirm that the required channel count matches the discrete five-channel specification rather than single-pair variants. Ensure compatibility with the target PCB footprint dimensions of 17.73mm by 12.19mm before finalizing procurement orders.

Selection Notes

Select this component when a discrete solution is preferred over integrated connector modules for 10GBASE-T designs. The 180 uH inductance and 1:1 ratio are critical for matching specific PHY requirements. Consider the 0°C to 70°C operating range to ensure suitability for commercial or light industrial environments without additional thermal management.

Part Context

This part belongs to the Pulse Electronics LAN transformer portfolio, specifically targeting high-speed Ethernet standards. It serves as a key isolation component in network interfaces, distinguishing itself from lower-speed counterparts like 1000Base-T modules through its higher frequency handling and multi-channel discrete configuration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify pinout and mechanical compatibility if considering alternative manufacturers for 10GBASE-T discrete transformers.
