H5020FNLT

Overview

The H5020FNLT is a surface-mount LAN pulse transformer manufactured by Pulse Electronics, designed for 10/100/1000 Base-T applications. It features a dual-channel configuration with a 1CT:1CT turns ratio for both transmitter and receiver sides. The component provides an inductance of 350µH and supports an insulation voltage of 1.5 kV. Operating within a temperature range of 0°C to +70°C, it utilizes SMD/SMT termination. The unit measures 27.94mm in length, 10.03mm in width, and has a maximum height of 8.64mm.

Feature Summary

• Supports 10/100/1000 Base-T Ethernet standards
• Dual-channel design for simultaneous transmission and reception
• Surface-mount construction for automated assembly

Applications

• Ethernet network interface cards
• Computer motherboard LAN ports
• Network switch internal circuitry

Procurement Notes

Verify the specific suffix 'FNL' against the datasheet to confirm the non-PoE variant and unshielded construction. Ensure the ordering code matches the reel or cut-tape packaging requirements. Confirm RoHS3 compliance status prior to final procurement approval.

Selection Notes

Select this component when a dual-channel solution is required for Gigabit Ethernet without Power over Ethernet capabilities. The standard operating temperature range suits general commercial environments. Verify board space constraints against the specified package dimensions before integration.

Part Context

This part belongs to the H5020 series of LAN transformers from Pulse Electronics. It serves as a signal isolation component in high-speed data communication circuits. The FNL suffix indicates a specific surface-mount package variation distinct from other family members like the HX5020FNLT which offers extended temperature ratings.

Replacement Considerations

HX5020FNLT is a verified substitute offering an extended operating temperature range of -40°C to 85°C while maintaining identical electrical parameters and footprint.
