Overview
The H5400NL is a surface mount audio and signal transformer manufactured by Pulse Electronics, designed for 1000Base-T Ethernet applications. It features a 4-port configuration with a 1:1 turns ratio. Key electrical parameters include an inductance of 350 µH and a DC resistance of 0.65 ohms. The component supports non-PoE operation and provides 1.5 kVrms isolation voltage. It is housed in a compact surface mount package suitable for high-density PCB layouts.
Feature Summary
- Designed specifically for 1000Base-T Ethernet interface compatibility
- Provides galvanic isolation between network ports
- Surface mount construction for automated assembly
Applications
- Gigabit Ethernet network interface cards
- Ethernet switches and routers
- Industrial networking equipment
Procurement Notes
Verify the specific suffix (e.g., NL) against the manufacturer's current datasheet to confirm pinout and packaging details. Ensure the selected variant matches the required isolation voltage and inductance specifications for the target 1000Base-T design. Cross-reference RoHS compliance status if environmental regulations apply to the end product.
Selection Notes
Select this component when a 4-port Gigabit Ethernet solution is required without Power over Ethernet capabilities. Confirm that the 350 µH inductance value aligns with the PHY transceiver requirements. Verify that the surface mount footprint fits within the available board space constraints.
Part Context
This part belongs to the Pulse Electronics LAN transformer family, which includes various configurations for different Ethernet speeds and port counts. The H5400NL is distinct from PoE-enabled variants, offering a simpler design for standard data transmission applications where power delivery over the network cable is not needed.
Replacement Considerations
Consult official substitution lists for compatible parts such as the H5400NLT or other 4-port 1000Base-T transformers from Pulse Electronics. Ensure any substitute maintains identical electrical characteristics and mechanical dimensions.
