HX5400NL

Overview

The HX5400NL is a four-channel LAN transformer module manufactured by Pulse Electronics, designed for 1000Base-T applications. It features surface mount technology (SMD/SMT) termination within a BGA package measuring 28.45 mm in length, 17.27 mm in width, and 11.18 mm in height. The component operates with an inductance of 350 uH and a maximum DC resistance of 650 mOhms. It supports a frequency range from 1 MHz to 125 MHz and provides 1.5 kV insulation voltage. The unit functions without Power over Ethernet (NonPoE) support and has an unshielded construction. Operating temperatures range from -40 C to +85 C.

Feature Summary

• Provides electrical isolation and signal coupling for four independent channels in Gigabit Ethernet networks.
• Designed specifically for non-PoE 1000Base-T data interface applications.
• Utilizes surface mount packaging for automated assembly integration.

Applications

• Gigabit Ethernet network interface cards
• Computer motherboards with integrated LAN ports
• Network switches and routers

Procurement Notes

Verify the specific suffix against official documentation to confirm shielding status and PoE compatibility, as variations exist within the series. Ensure the procurement source provides valid manufacturer traceability. Confirm that the received components match the specified 350 uH inductance and 650 mOhms DC resistance parameters. Check for RoHS compliance documentation if required by project specifications. Validate the BGA package dimensions against the PCB footprint design.

Selection Notes

Select this component when designing systems requiring isolated Gigabit Ethernet connections without Power over Ethernet delivery. The four-channel configuration supports full duplex communication on all pairs simultaneously. Consider the unshielded nature of this specific variant when evaluating electromagnetic interference requirements relative to shielded alternatives like the HX5401NLT. Ensure the operating temperature range meets the environmental conditions of the target deployment.

Part Context

This part belongs to the Gigabit 10/100/1000BASE-T series produced by Pulse Electronics. It serves as a critical passive component for maintaining signal integrity and galvanic isolation in high-speed data transmission lines. The module integrates magnetics typically found in discrete transformer designs into a compact surface-mount form factor.

Replacement Considerations

The HX5401NLT is a similar quad transformer but differs in shielding characteristics. Verify functional equivalence regarding pinout and electrical parameters before substitution. Other single-port variants such as the HX5008NLT are not direct replacements due to channel count differences.
