H5201NL

Overview

The H5201NL is a LAN transformer module manufactured by Pulse Electronics, designed for 1000Base-T applications. It features a dual-port configuration with surface mount (SMD/SMT) termination. Key electrical parameters include an inductance of 350 uH and a DC resistance of 0.65 Ohms. The component supports a frequency range from 1 MHz to 100 MHz and provides an insulation voltage of 1.5 kV. It operates within a temperature range of -40 C to +85 C. The physical dimensions are 17.27 mm in length, 14.73 mm in width, and 10.67 mm in height. The unit is unshielded and belongs to the HX series.

Feature Summary

• Supports 1000Base-T Ethernet standards with dual-port capability
• Surface mount construction for automated PCB assembly
• High insulation voltage rating for signal isolation
• Wide operating temperature range suitable for industrial environments

Applications

• 1000Base-T network interface cards
• Ethernet switch ports
• Industrial networking equipment
• Computer motherboards with Gigabit connectivity

Procurement Notes

Verify the specific datasheet version for the H5201NL to confirm RoHS compliance details and exact pinout configurations before integration. Ensure that the surface mount footprint matches the design layout, as dimensions are critical for SMD placement. Cross-reference the manufacturer's latest documentation to validate the absence of lead time constraints or obsolescence notices, as supply chain statuses can change without public announcement.

Selection Notes

Select the H5201NL when a dual-port solution is required for Gigabit Ethernet designs. Its wide temperature range makes it suitable for harsher environments compared to commercial-grade alternatives. Verify that the non-shielded nature aligns with the system's electromagnetic interference requirements. Compare against single-port variants if only one channel is needed to optimize board space and cost.

Part Context

This component is part of Pulse Electronics' audio and signal transformer portfolio, specifically categorized under LAN transformers. It serves as a critical interface between the Ethernet PHY and the magnetics, ensuring signal integrity and isolation. The HX series designation indicates its place within the manufacturer's broader lineup of networking magnetics solutions.
