H5062FNLT

Overview

The H5062FNLT is a single-port LAN pulse transformer module manufactured by Pulse Electronics, designed for 10/100/1000 Base-T applications with Power over Ethernet (PoE) support. It features surface mount termination and operates within a frequency range of 1 MHz to 100 MHz. Key electrical specifications include an inductance of 350 µH, an insulation voltage of 1.5 kV, and a primary DC resistance of 0.65 Ohms. The component supports a 1:1 turns ratio for both transmitter and receiver circuits. It functions reliably across a temperature range of 0°C to +70°C and is packaged in tape and reel format for automated assembly.

Feature Summary

• Supports Power over Ethernet (PoE) functionality integrated into the single-port design
• Provides galvanic isolation with 1.5 kV insulation voltage rating
• Optimized for Gigabit Ethernet (1000 Base-T) signal transmission integrity

Applications

• Gigabit Ethernet network interface cards
• PoE-enabled networking switches
• Industrial communication equipment requiring isolated signal coupling

Procurement Notes

Verify that the specific ordering suffix matches the required packaging configuration, as variations exist between tube and tape-and-reel formats. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant aligns with the PoE requirements of the target circuit design. Cross-reference the datasheet for exact pinout definitions to prevent soldering errors during surface mount placement.

Selection Notes

Select this component when a single-port solution with integrated PoE capability is required for Gigabit Ethernet designs. Compare against non-PoE variants if power delivery is not needed, or dual-port models for multi-interface applications. Consider the physical dimensions of 17.5 mm x 15.24 mm for PCB layout constraints. Validate thermal performance within the specified 0°C to +70°C operating range for the intended environment.

Part Context

This part belongs to the Pulse Transformers family, specifically engineered for local area network connectivity. It serves as a critical interface component between the Ethernet PHY and the magnetic coupler, ensuring signal integrity and electrical safety. The module integrates multiple windings into a compact surface-mount package, simplifying the design process for high-speed data transmission systems.
