H1199FNL

Overview

The H1199FNL is a LAN pulse transformer module designed for 10/100 Base-T applications. It features a single-channel configuration with a primary-to-secondary turns ratio of 1CT:1CT for both transmitter and receiver sections. The component provides an inductance of 350µH and supports surface mount installation. It operates within a temperature range of 0°C to 70°C. Physical dimensions are 12.70mm length, 9.09mm width, and 5.99mm height maximum.

Feature Summary

• Provides galvanic isolation for data interface signals in Ethernet networks
• Supports 10/100 Base-T transmission standards with integrated magnetics
• Features a compact surface-mount package suitable for automated assembly

Applications

• 10/100 Base-T Ethernet network interfaces
• LAN port signal conditioning modules
• Data communication equipment requiring isolated transformers

Procurement Notes

Verify the specific suffix designation when sourcing replacements. Confirm that the required component matches the FNL packaging format rather than NL variants, as physical dimensions and mounting characteristics differ between these series options. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component for designs requiring standard 10/100 Base-T magnetics without Power over Ethernet capabilities. The non-PoE specification distinguishes it from PoE-enabled counterparts. Consider the operating temperature range of 0°C to 70°C against environmental requirements. Verify that the unshielded construction meets electromagnetic interference constraints for the target application.

Part Context

This part belongs to the Pulse Electronics LAN Transformers product line. It serves as a magnetics solution for basic Ethernet connectivity. The HX series typically encompasses various configurations for different IEEE standards. This specific model addresses common industrial and commercial networking hardware needs.

Replacement Considerations

The H1199FNLT is documented as a parameter-equivalent substitute. Verify mechanical fit and electrical specifications before substitution. Other listed equivalents include H1302FNL and H1302FNLT.
