H7018FNLT

Overview

The H7018FNLT is a surface mount LAN 10G Base-T pulse transformer manufactured by Pulse Electronics. It features an inductance of 120µH and a turns ratio of 1:1. The component supports a minimum isolation voltage of 1500 Vrms and operates within a temperature range of 0°C to 70°C. It utilizes a 24-pin configuration with physical dimensions of 13.70mm length, 15.00mm width, and a maximum height of 5.85mm.

Feature Summary

• Designed for 10G Base-T LAN applications
• Surface mount construction with open frame design
• Single port configuration

Applications

• 10 Gigabit Ethernet network interfaces
• LAN signal transmission systems
• Ethernet transformer modules

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging format, such as tape and reel or cut tape, as these affect handling procedures. Confirm that the RoHS3 compliance status meets current environmental regulations for the target assembly. Ensure the MSL level 1 rating aligns with the facility's reflow soldering capabilities without requiring special moisture barrier bag storage protocols prior to use.

Selection Notes

Select this component when a single-port 10G Base-T solution is required for space-constrained designs. The 1:1 turns ratio suits direct coupling requirements. Verify that the 1500 Vrms isolation voltage satisfies the safety standards for the intended network segment. The open frame construction may require careful mechanical consideration regarding shielding compared to enclosed alternatives.

Part Context

This part belongs to the H70xx series of integrated connector modules and discrete transformers from Pulse Electronics. It serves as a critical passive component for high-speed data integrity in modern networking hardware. The product line focuses on providing reliable signal coupling for gigabit and multi-gigabit ethernet standards.

Replacement Considerations

The H7029FNLT is a documented substitute offering similar 10G Base-T specifications and physical footprint. Verify pin compatibility and electrical parameters before substitution.
