H1102NL

Overview

The H1102NL is a single-port LAN transformer module manufactured by Pulse Electronics, designed for surface-mount (SMD/SMT) applications. It supports 100Base-TX Ethernet standards with an inductance of 350 uH and a DC resistance of 0.65 Ohms. The component operates within a frequency range of 100 kHz to 100 MHz and provides 1.5 kV isolation voltage. Physical dimensions are 12.7 mm in length, 9.53 mm in width, and 6.09 mm in height. It functions without PoE support and is rated for operating temperatures between 0°C and +70°C.

Feature Summary

• Provides signal isolation and impedance matching for 100Base-TX networks
• Complies with IEEE 802.3 specifications for network integrity
• Features compact open-frame construction suitable for space-constrained designs

Applications

• Network interface cards
• Ethernet hubs and routers
• Communication equipment transceivers

Procurement Notes

Verify the specific ordering suffix to confirm package type, as variants exist with different packaging formats such as tubes or reels. Ensure the selected part number matches the required RoHS compliance status and lead-free soldering requirements for the target assembly process. Cross-reference the manufacturer datasheet for precise reflow temperature profiles and handling instructions.

Selection Notes

Select this component for standard 10/100 Mbps Ethernet interfaces requiring non-PoE solutions. The unshielded design may require careful PCB layout to manage EMI. Verify that the thermal rating of +70°C aligns with the environmental conditions of the final device enclosure. Confirm footprint compatibility with existing board designs before integration.

Part Context

This component belongs to the Pulse Electronics LAN Transformers series, specifically engineered for audio and signal transformation in networking hardware. It serves as a critical interface between the MAC controller and the physical medium, ensuring electrical isolation and signal quality across twisted-pair cabling systems.
