H5009FNL

Overview

The H5009FNL is a single-port LAN pulse transformer manufactured by Pulse Electronics, designed for 10/100/1000 Base-T applications. It features a surface-mount package with dimensions of 0.538 inches in length and 0.726 inches in width. The device operates within a temperature range of 0°C to 70°C and has an inductance of 350µH. The turns ratio is specified as 1CT:1CT for both the transmitter and receiver sections.

Feature Summary

• Supports Gigabit Ethernet (10/100/1000 Base-T) data transmission standards
• Integrated transmitter and receiver isolation in a single module
• Surface-mount construction for automated assembly processes

Applications

• Gigabit Ethernet network interface cards
• Ethernet switches and routers
• Network infrastructure equipment requiring 10/100/1000 Base-T connectivity

Procurement Notes

Verify the specific suffix requirements when ordering, as variants such as H5009FNLT exist with different packaging options like tape and reel. Confirm that the standard tube packaging aligns with your manufacturing line capabilities. Ensure compatibility with RoHS3 regulations if required by your project specifications. Cross-reference the exact part number with official distributor catalogs to avoid confusion between similar model numbers in the H5009 series.

Selection Notes

Select this component when designing systems requiring integrated isolation for Gigabit Ethernet ports. The 350µH inductance value is critical for maintaining signal integrity at high frequencies. Consider the physical footprint of 0.538 x 0.726 inches during PCB layout planning. Verify thermal management needs against the 0°C to 70°C operating range. This part is suitable for space-constrained designs where combined TX/RX functionality reduces board area.

Part Context

This component belongs to Pulse Electronics' LAN transformer portfolio, specifically engineered for high-speed data communication. It serves as a key isolation element in Ethernet PHY circuits. The H5009 series offers various packaging options to suit different production volumes. It is distinct from lower-speed transformers used in 10/100 Base-T applications due to its optimized frequency response for Gigabit speeds.

Replacement Considerations

The H5004NL is listed as a parameter-equivalent alternative for single-port 1000Base-T applications. Verify dimensional compatibility and electrical specifications before substitution. Other models in the H5009 family may offer different packaging or temperature ratings.
