H7019FNL

Overview

The H7019FNL is a surface-mount pulse transformer designed for 10G Base-T LAN applications. It features a single port configuration with a 1:1 turns ratio. The component provides an inductance of 200 µH and supports an isolation voltage of 1.5 kV. It operates within a temperature range of 0°C to +70°C and functions across a frequency range of 1 MHz to 500 MHz.

Feature Summary

• Designed specifically for 10G Base-T network interfaces
• Surface mount construction for automated assembly
• Single port topology with 1:1 signal coupling

Applications

• 10 Gigabit Ethernet physical layer circuits
• Network interface card (NIC) designs
• Server and switch motherboard implementations

Procurement Notes

Verify the specific revision level against the manufacturer's current documentation, as part numbers may have suffix variations indicating minor manufacturing updates. Confirm that the surface mount footprint matches the target PCB design constraints. Ensure the operating temperature range aligns with the final system environment requirements before integration.

Selection Notes

Select this component when a dedicated 10G Base-T solution is required without Power over Ethernet capabilities. The 200 µH inductance value is critical for maintaining signal integrity at high frequencies. Consider the 1.5 kV isolation rating for safety compliance in relevant network infrastructure deployments.

Part Context

This transformer belongs to Pulse Electronics' portfolio of passive components for high-speed data communication. It serves as a key interface element between the MAC and PHY layers in Ethernet systems. The device replaces older copper-wound variants with modern surface-mount technologies for improved reliability.
