H1260NLT

Overview

The H1260NLT is a single-port LAN pulse transformer module manufactured by Pulse Electronics, designed for 100Base-TX applications. It features surface mount (SMD/SMT) termination and operates within a frequency range of 100 kHz to 100 MHz. The component has an inductance of 350 uH and provides an insulation voltage of 1.5 kV. Physical dimensions are 12.7 mm in length, 9.65 mm in width, and 6 mm in height. It supports a single channel and functions as an unshielded unit. The operating temperature range spans from 0°C to +70°C.

Feature Summary

• Provides signal isolation and impedance matching for 100Base-TX Ethernet networks
• Supports non-PoE configurations with single-channel architecture
• Utilizes surface mount technology for automated assembly integration

Applications

• 100Base-TX Ethernet network interface cards
• LAN port signal conditioning modules
• Industrial communication equipment requiring 10/100 Mbps connectivity

Procurement Notes

Verify the specific RoHS compliance status through official manufacturer documentation prior to procurement. Confirm that the selected variant matches the required NonPoE specification for the target application. Ensure that the SMD package dimensions align with the PCB footprint design constraints. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability of the component batch.

Selection Notes

Select this component when designing for 100Base-TX standards requiring single-port isolation without Power over Ethernet capabilities. Consider the 1.5 kV insulation voltage rating for safety requirements. Evaluate the 0°C to +70°C operating temperature range against environmental conditions. Verify that the unshielded design does not conflict with electromagnetic interference constraints in the final assembly.

Part Context

This component belongs to the audio and signal transformer category, specifically classified under LAN transformers. It is part of Pulse Electronics' portfolio of magnetic components for data communication interfaces. The module serves as a critical interface element between the Ethernet PHY controller and the physical cable connector, ensuring signal integrity and electrical isolation.
