H5008NLT

Overview

The H5008NLT is a Gigabit LAN pulse transformer module manufactured by Pulse Electronics, designed for surface-mount assembly. It supports 10/100/1000 Base-T Ethernet standards with a single port configuration. The component features a 350µH inductance and a turns ratio of 1CT:1CT for both transmitter and receiver circuits. It operates within a temperature range of 0°C to 70°C and utilizes a 24-SOIC package measuring 18.87mm x 13.67mm x 5.87mm.

Feature Summary

• Provides electrical circuit isolation compliant with IEEE 802.3 standards for signal integrity
• Optimized for integration with major LAN transceivers in compact surface-mount form factors
• Supports high peak reflow temperature ratings suitable for automated manufacturing processes

Applications

• Gigabit Ethernet network interface cards
• Industrial communication equipment requiring isolated data links
• Consumer networking hardware such as routers and switches

Procurement Notes

Verify the specific suffix 'NL' against current datasheets to confirm pinout compatibility and RoHS3 compliance status. Ensure the selected packaging option matches the production line requirements, as reel quantities and tape specifications may vary between distributors. Cross-reference the manufacturer part number with official Pulse Electronics documentation to validate recent design changes or obsolescence notices before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring integrated isolation for Gigabit Ethernet applications without external discrete transformers. Consider the 24-SOIC footprint constraints and the specified operating temperature range of 0°C to 70°C during thermal management planning. Verify that the 350µH inductance value aligns with the impedance matching requirements of the target PHY transceiver chip.

Part Context

This module belongs to Pulse Electronics' LAN discrete transformer series, which are engineered to meet strict IEEE 802.3 isolation requirements. The product line emphasizes signal integrity and reliability for demanding network environments. The H5008NLT represents a standard solution for single-port Gigabit connectivity, replacing older through-hole or larger surface-mount alternatives in modern PCB layouts.
