H5077NL

Overview

The H5077NL is a single-port, surface-mount LAN transformer module designed for 1000BASE-T Gigabit Ethernet applications. It features a 1:1 turns ratio and operates within a frequency range of 1 MHz to 100 MHz. The component provides 1.5 kV isolation voltage and has a common mode inductance of 350 uH. Primary and secondary coil resistances are specified at 1 Ohm each. The module measures 13.97 mm in length, 12.57 mm in width, and 4.57 mm in height. It supports an operating temperature range from 0°C to +70°C and is RoHS compliant.

Feature Summary

• Supports 1000BASE-T Gigabit Ethernet data transmission standards
• Provides galvanic isolation with 1.5 kV dielectric strength
• Designed for surface mount technology (SMD) integration
• Unshielded construction suitable for standard PCB layouts

Applications

• Gigabit Ethernet network interface cards
• Ethernet switch port interfaces
• Industrial networking equipment
• Consumer electronic devices with Gigabit connectivity

Procurement Notes

Verify the specific manufacturer datasheet for the H5077NL to confirm current production status and compliance certifications. Ensure that the selected supplier provides authentic components from Pulse Electronics or authorized distributors. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring a single-port, non-PoE solution for Gigabit Ethernet. The unshielded design may require careful layout considerations to minimize electromagnetic interference. Verify that the board space accommodates the 13.97 mm x 12.57 mm footprint and that the thermal environment remains within the 0°C to +70°C operational limits.

Part Context

This part belongs to the H5077 series of Mini-Magnetics modules from Pulse Electronics. These modules integrate magnetics for Ethernet ports into a compact surface-mount package. The series is intended for high-density applications where space constraints are critical. The H5077NL specifically targets non-Power over Ethernet implementations for standard Gigabit connections.

Replacement Considerations

Direct replacements include the H5007NL from the same manufacturer family. Both parts serve similar 1000BASE-T functions but differ in physical dimensions and packaging. Verify compatibility with existing PCB footprints and electrical specifications before substituting.
