H1102NLT

Overview

The H1102NLT is a single-port LAN transformer module manufactured by Pulse Electronics, designed for surface-mount assembly. It supports 100Base-TX Ethernet applications without Power over Ethernet (PoE) requirements. Key electrical specifications include an inductance of 350 uH and a DC resistance of 0.65 Ohms. The device features a 1:1 turns ratio for both transmitter and receiver paths. It operates within a frequency range of 100 kHz to 100 MHz and withstands an isolation voltage of 1.5 kV. The component functions reliably between 0°C and +70°C.

Feature Summary

Integrated magnetic module providing galvanic isolation for Ethernet signal transmission
Optimized for non-PoE 100Base-TX network interface implementations
Surface-mount construction suitable for automated PCB assembly processes

Applications

100Base-TX Ethernet port circuits
Network interface card (NIC) designs
Industrial communication equipment requiring isolated LAN connections

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and reel configuration. Ensure compatibility with RoHS3 standards if required by project regulations. Cross-reference manufacturer part numbers with distributor listings to avoid substitution errors during sourcing.

Selection Notes

Select this component for standard 10/100 Mbps Ethernet interfaces where PoE is not utilized. Confirm that the 1.5 kV isolation rating meets safety requirements for the target application environment. Verify footprint dimensions match the PCB layout constraints before finalizing the design.

Part Context

This component belongs to Pulse Electronics' LAN transformer portfolio, specifically engineered for data communication interfaces. It serves as a critical passive element in Ethernet PHY circuits, ensuring signal integrity and electrical isolation between the transceiver and the physical medium connector.
