H1197FNL

Overview

The H1197FNL is a surface mount LAN pulse transformer manufactured by Pulse Electronics. It supports 10/100 Base-T Ethernet applications and features a single port configuration with a 1CT:1CT turns ratio for both transmitter and receiver circuits. The component has an inductance of 1.2mH and operates within a temperature range of 0°C to 70°C. Its physical dimensions are 12.70mm in length, 9.09mm in width, and a maximum height of 5.99mm.

Feature Summary

• Provides galvanic isolation for data interfaces in LAN environments
• Supports 10/100 Base-T transmission standards
• Designed for surface mount assembly processes

Applications

• 100BaseTX network interface cards
• Ethernet switch ports
• Network adapter modules

Procurement Notes

Verify the specific suffix 'FNL' against the manufacturer's current datasheet to confirm package type and marking specifications. Ensure the design accommodates the required surface mount footprint and thermal characteristics. Confirm RoHS3 compliance status if required by local regulations before finalizing procurement orders.

Selection Notes

Select this component for designs requiring isolated LAN transformers for 10/100 Mbps speeds. It is suitable for non-PoE applications where specific inductance values are required. Compare physical dimensions against available PCB space constraints. Verify compatibility with automated pick-and-place equipment due to its surface mount form factor.

Part Context

This part belongs to the H1197 series of LAN transformers from Pulse Electronics. It serves as a direct replacement for the H1197FNLT variant, differing primarily in packaging format. The series is designed for compact networking equipment requiring reliable signal integrity over twisted pair cables.

Replacement Considerations

The H1197NLT is listed as a direct substitute. Verify that the packaging difference does not impact the assembly line configuration or inventory management systems.
