Overview
The HX2019NLT is a LAN signal transformer module manufactured by Pulse Electronics, designed for surface-mount technology. It supports 10/100 Base-T Ethernet applications with a 1CT:1CT turns ratio for both transmitter and receiver circuits. The component features a 350µH inductance and operates within a temperature range of -40°C to +85°C. It provides 1500Vrms isolation voltage and meets RoHS3 standards. The package dimensions are 12.70mm x 9.09mm x 5.99mm.
Feature Summary
- Provides electrical circuit isolation compliant with IEEE 802.3 standards for LAN transceivers.
- Optimized for 10/100 Base-T signal integrity in demanding network applications.
- Supports peak reflow temperatures up to +245°C for robust SMT assembly.
Applications
- 10/100 Base-T Ethernet network interfaces
- LAN discrete transformer modules
- Signal transformers for network transceivers
Procurement Notes
Verify the specific suffix 'NLT' against official datasheets to confirm packaging type, as variations may exist between tape-and-reel and cut-tape formats. Ensure compatibility with AEC-Q200 requirements if automotive qualification is needed, though this model is primarily specified for general LAN use. Confirm moisture sensitivity level (MSL 1) handling procedures during storage and assembly.
Selection Notes
Select the HX2019NLT for applications requiring 10/100 Base-T isolation with a 1CT:1CT configuration. Consider the 350µH inductance and 1500Vrms isolation rating for standard Ethernet PHY connections. Evaluate the SMD/SMT footprint (12.70mm x 9.09mm) for PCB space constraints. Verify operating temperature range (-40°C to +85°C) matches environmental conditions.
Part Context
This component belongs to Pulse Electronics' LAN discrete transformer modules series, optimized for major LAN transceivers. It falls under the broader category of audio and signal transformers, specifically serving as a common mode filter choke or signal transformer for network connectivity. The product line emphasizes signal integrity and electrical isolation for Ethernet standards.
Replacement Considerations
The HX2019NL is a related variant with identical core specifications but potentially different packaging. Cross-reference datasheets to ensure pinout and mechanical dimensions match before substitution. No other direct public substitutes are confirmed in the provided documentation.
