H1197FNLT

Overview

The H1197FNLT is a surface mount pulse transformer manufactured by Pulse Electronics, designed for LAN 10/100 Base-T applications. It features a 1CT:1CT turns ratio for both transmitter and receiver channels with an inductance of 1.2mH. The component measures 12.70mm x 9.09mm x 5.99mm and operates within a temperature range of 0°C to 70°C. It supports non-PoE Ethernet signaling and complies with RoHS3 standards.

Feature Summary

• Integrated pulse transformer module for isolated data interfaces
• Optimized for 10/100 Base-T LAN transmission and reception
• Surface mount construction for automated assembly

Applications

• Ethernet network interface cards
• LAN port isolation circuits
• Industrial communication modules

Procurement Notes

Verify the specific suffix 'FNLT' against design requirements, as it denotes tape-and-reel packaging distinct from bulk variants like 'FNL'. Confirm RoHS3 compliance status for environmental regulations. Check lead times as standard delivery may vary. Ensure compatibility with existing PCB footprint dimensions of 12.70mm x 9.09mm.

Selection Notes

Select this component for 10/100Base-T designs requiring non-PoE isolation. The 1.2mH inductance suits standard Ethernet PHY implementations. Compare physical height of 5.99mm against board clearance constraints. Consider the H1197NLT if Power over Ethernet functionality is required instead.

Part Context

This part belongs to Pulse Electronics' LAN transformer portfolio. It serves as a signal conditioning and isolation element between the Ethernet PHY and the magnetics jack. The 'FNLT' designation indicates a specific reel configuration within the H1197 series family.

Replacement Considerations

H1197NLT is listed as a direct substitute. H1197FNL is available as a parameter-equivalent alternative in bulk packaging.
