HX1198NLT

Overview

The HX1198NLT is a surface-mount pulse transformer module manufactured by Pulse Electronics, designed for LAN isolation applications. It supports 10/100 Base-T Ethernet standards with a single port configuration and a 1:1 turns ratio for both transmitter and receiver circuits. The component features an inductance of 350µH and operates within a temperature range of -40°C to +85°C. Its physical dimensions are 12.70mm in length, 7.11mm in width, and a maximum height of 6.22mm. The device provides electrical circuit isolation compliant with IEEE 802.3 standards while maintaining signal integrity.

Feature Summary

• Provides electrical circuit isolation for data interfaces meeting IEEE 802.3 standards
• Optimized for 10/100 Base-T Ethernet transceivers to maintain signal integrity
• Surface mount construction suitable for automated PCB assembly processes

Applications

• 10/100 Base-T network interface cards
• Ethernet switch ports
• Network adapter modules

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging format, as variants exist for tape and reel, cut tape, or Digi-Reel configurations. Confirm that the non-PoE specification aligns with the design requirements, as this model does not support Power over Ethernet. Check RoHS3 compliance status if required by environmental regulations. Ensure the single-port topology matches the schematic design before procurement.

Selection Notes

Select this component for designs requiring isolation on 10/100 Mbps Ethernet links without PoE capabilities. The 350µH inductance value is standard for these frequency ranges. Consider the compact SMD footprint for space-constrained layouts. Verify compatibility with the target transceiver's impedance matching requirements. This module is suitable for general LAN applications where high-speed Gigabit performance is not required.

Part Context

This part belongs to the HX series of LAN discrete transformer modules from Pulse Electronics. These modules are engineered to provide reliable isolation between the PHY chip and the external network medium. The series typically includes variants for different speeds such as 10/100 and 1000 Base-T, with options for PoE and non-PoE implementations. The HX1198NLT specifically addresses the lower speed tier of Ethernet connectivity.
