H5015FNLT

Overview

The H5015FNLT is a surface-mount LAN pulse transformer manufactured by Pulse Electronics, designed for 10/100/1000 Base-T applications. It features a 350µH inductance with a 1CT:1CT turns ratio for both transmitter and receiver channels. The component measures 17.66mm x 15.14mm x 4.57mm and operates within a temperature range of 0°C to 70°C. It complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 1.

Feature Summary

• Supports Gigabit Ethernet data transmission rates up to 1000 Mbps
• Integrated dual-channel design for simultaneous transmit and receive functions
• Optimized for surface-mount technology assembly processes

Applications

• Gigabit Ethernet network interface cards
• Ethernet switch port circuits
• Industrial networking equipment

Procurement Notes

Verify the specific suffix 'FNLT' to ensure receipt of the tape-and-reel packaging variant rather than the tube-packaged 'FNL'. Confirm that the non-PoE designation aligns with the circuit requirements, as this model lacks integrated power over Ethernet components. Check current lifecycle status as some sources indicate it may be not recommended for new designs.

Selection Notes

Select this component when a compact SMD solution is required for full-duplex Gigabit Ethernet signaling. Ensure the board layout accommodates the 17.66mm length dimension. Compare against the H5015FNL if tube packaging is preferred for manual assembly or lower volume prototyping, noting the identical electrical characteristics.

Part Context

This part belongs to Pulse Electronics' LAN transformer family, specifically engineered for high-speed data communication. It serves as a critical isolation and impedance matching element between the Ethernet PHY and the magnetics module. The FNLT suffix denotes the reel packaging format, distinguishing it from other variants in the same electrical specification group.

Replacement Considerations

The H5015FNL is listed as a parameter-equivalent alternative, differing primarily in packaging type. Other electrically similar models include the H5014FNLT and H6080FNL, though physical dimensions and pin configurations should be verified before substitution.
