H5401NL

Overview

The H5401NL is a quad-channel LAN transformer module manufactured by Pulse Electronics, designed for Surface Mount Device (SMD) applications. It supports 1000Base-T Ethernet standards and operates within a frequency range of 100 kHz to 200 MHz. Key electrical parameters include an inductance of 350 uH, a maximum DC resistance of 65 mOhms, and an insulation voltage of 1.5 kV. The component features four ports with a 1:1 turns ratio and measures 28.45 mm in length, 17.27 mm in width, and 11.18 mm in height. It functions without Power over Ethernet (PoE) capabilities and is rated for operating temperatures between -40 C and +85 C.

Feature Summary

• Provides signal isolation and impedance matching for Gigabit Ethernet interfaces
• Supports high-speed data transmission up to 1000 Mbps via 1000Base-T standard
• Features unshielded construction for compact surface-mount integration

Applications

• 1000Base-T network interface cards
• Ethernet switch port circuits
• Gigabit router hardware modules

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and detailed pinout configurations. Ensure that the application design does not require Power over Ethernet functionality, as this model is specified for non-PoE operations only. Cross-reference mechanical dimensions with PCB footprint requirements to guarantee proper SMD placement and soldering integrity during assembly processes.

Selection Notes

Select this component when designing Gigabit Ethernet systems requiring isolated signal paths without PoE power delivery. The quad-channel architecture suits multi-port networking devices. Consider the unshielded nature for EMI-sensitive environments and verify thermal management capabilities within the specified -40 C to +85 C operational range for reliable long-term performance.
