- Supports 10G Base-T transmission standards
- Designed for surface mount assembly
Applications
- LAN 10G Base-T network equipment
- Network interface card designs
- Signal isolation circuits
Procurement Notes
Verify the specific suffix designation when ordering, as variations such as FNLT indicate tape and reel packaging options. Confirm that the selected variant matches the required surface mount form factor and electrical specifications for the target application. Ensure compliance with RoHS3 standards if environmental regulations apply to the manufacturing process.
Selection Notes
Select this component for applications requiring dedicated pulse transformers for 10G Base-T Ethernet interfaces. Consider the physical footprint constraints due to its specific surface mount dimensions. Evaluate the operating temperature range to ensure suitability for the intended environmental conditions during network data transmission.
Part Context
This part belongs to the Pulse Electronics audio and signal transformer category, specifically designed for LAN applications. It serves as a critical passive component for maintaining signal quality in high-speed networking hardware. The product line supports various Ethernet standards through specialized transformer modules.
Replacement Considerations
The H1270NLT is documented as a discontinued alternative or predecessor model. Designers should verify compatibility when considering substitutions, as packaging and availability status differ between the active H1270FNL and the obsolete H1270NLT.
