Overview
The HX5020FNL is a surface-mount LAN transformer module designed for 10/100/1000 Base-T applications. It features a dual-channel configuration with a 350 µH inductance and a .65 Ohm resistance. The component supports a frequency range of 1 MHz to 100 MHz and provides 1.5 kV isolation voltage. It operates within a temperature range of -40°C to +85°C. The package dimensions are 27.94 mm in length, 10.92 mm in width, and 8.33 mm in height.
Feature Summary
- Dual-channel design supporting 1CT:1CT transmitter and receiver configurations
- Non-PoE compatible architecture for standard Gigabit Ethernet signaling
- Surface-mount termination suitable for automated assembly processes
Applications
- Gigabit Ethernet network interface cards
- Industrial communication modules requiring non-PoE isolation
- Consumer networking hardware utilizing 10/100/1000 Base-T standards
Procurement Notes
Verify the specific suffix designation when ordering, as variants such as HX5020FNLT exist with different packaging formats. Confirm that the application does not require Power over Ethernet functionality, as this model is specified for non-PoE use cases. Ensure compatibility with the required thermal management specifications for the intended operating environment.
Selection Notes
Select this component for designs requiring integrated signal conditioning and isolation for Gigabit Ethernet ports. The dual-channel layout simplifies board space requirements compared to discrete solutions. Consider the physical footprint constraints against the 27.94 mm length dimension during PCB layout planning.
Part Context
This part belongs to the HX series of audio and signal transformers manufactured by Pulse Electronics. The series includes various configurations tailored for different Ethernet speeds and PoE requirements. The HX5020FNL specifically addresses the needs for high-speed data transmission without power delivery capabilities.
Replacement Considerations
The HX5020FNLT serves as a packaging variant of this component. Verify mechanical fit and electrical equivalence before substituting with other models from the HX family or competing manufacturers.
