H1260FNLT

Overview

The H1260FNLT is a single-channel LAN pulse transformer module manufactured by Pulse Electronics. Designed for surface-mount assembly, it supports 100Base-TX and 10G Base-T applications without Power over Ethernet (PoE) functionality. The component features an inductance of 350 µH and operates within a frequency range of 100 kHz to 100 MHz. It provides 1.5 kV isolation voltage and functions between 0°C and +70°C. Physical dimensions are 12.7 mm x 9.09 mm x 5.99 mm.

Feature Summary

• Supports 100Base-TX and 10G Base-T signal transmission standards
• Non-PoE configuration for dedicated data line isolation
• Single-channel architecture with 1:1 turn ratio for transmitter and receiver paths

Applications

• 100Base-TX Ethernet network interface circuits
• 10G Base-T physical layer transceiver modules
• LAN port signal conditioning and isolation

Procurement Notes

Verify the specific datasheet revision to confirm compatibility with current design requirements. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel. Confirm RoHS compliance status and moisture sensitivity level before integration into the manufacturing process.

Selection Notes

Select this component when a single-port, non-Powered-over-Ethernet solution is required for 100Base-TX or 10G Base-T systems. The unshielded design suits applications where external shielding is managed separately. Verify that the 350 µH inductance aligns with the PHY specifications.

Part Context

This part belongs to Pulse Electronics' LAN Transformers series, specifically engineered for high-speed data communication interfaces. It serves as a critical isolation component between the magnetics and the physical layer controller in Ethernet networking hardware.
