H1260NL

Overview

The H1260NL is a single-port LAN transformer module manufactured by Pulse Electronics, designed for 100BaseTX applications. It features surface mount (SMD/SMT) termination and operates within a frequency range of 100 kHz to 100 MHz. Key electrical parameters include an inductance of 350 uH and an insulation voltage of 1.5 kV. The component has a physical footprint of 17.53 mm in length, 16 mm in width, and 5.51 mm in height. It supports an operating temperature range from 0°C to +70°C and is supplied in tube packaging.

Feature Summary

• Designed specifically for 100BaseTX Ethernet signal transmission
• Provides galvanic isolation with 1.5 kV insulation voltage
• Surface mount construction for automated assembly integration

Applications

• 100BaseTX network interface circuits
• Ethernet LAN port implementations
• Signal transformation in non-PoE network hardware

Procurement Notes

Verify the specific package type upon ordering, as the H1260NLT variant utilizes cut tape or reel packaging while the H1260NL typically uses tube packaging. Confirm RoHS compliance status through official manufacturer documentation prior to finalizing procurement contracts. Ensure the selected part number matches the required mounting style for the target PCB design.

Selection Notes

Select this component for standard 10/100 Mbps Ethernet designs requiring single-port isolation. Compare against the H1260NLT if reel-based surface mount processing is preferred over tube packaging. Verify that the 350 uH inductance and 1.5 kV isolation rating meet the specific circuit requirements for noise immunity and safety standards.

Part Context

This component belongs to the Pulse Electronics LAN Transformers category, specifically under Audio & Signal Transformers. It serves as a critical interface element between the Ethernet PHY chip and the external cable jack, ensuring signal integrity and electrical safety in wired networking equipment.

Replacement Considerations

The H1260NLT is a related variant offering identical electrical specifications but differs in packaging format, utilizing cut tape or reel instead of tubes. Direct substitution requires verification of the PCB land pattern compatibility with the respective package styles.
