H5078NL

Overview

The H5078NL is a LAN transformer module manufactured by Pulse Electronics, designed for 1000Base-T applications. It features a single channel with surface mount (SMD/SMT) termination. The component operates within a frequency range of 1 MHz to 100 MHz and has an inductance of 350 uH. Primary and secondary coil impedances are specified at 1 Ohm each. Electrical isolation is rated at 1.5 kV. The device supports an operating temperature range from 0°C to +70°C. Physical dimensions are approximately 13.97 mm in length, 12.57 mm in width, and 4.57 mm in height. The unit weight is 1.140 g.

Feature Summary

Supports 1000Base-T Gigabit Ethernet data transmission standards
Provides electrical isolation between network lines
Designed for surface mount assembly processes

Applications

Gigabit Ethernet network interface cards
Ethernet switch port circuits
Network adapter hardware

Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to integration. Confirm that the package dimensions and pinout align with the target PCB footprint design. Ensure thermal management strategies accommodate the specified operating temperature range during final product validation.

Selection Notes

Select this component for designs requiring standard 1000Base-T isolation without Power over Ethernet capabilities. Compare physical size constraints against alternative modules like the H5062NL or HX5008NL if space limitations exist. Validate impedance matching requirements against the specific PHY controller being utilized in the circuit architecture.

Part Context

This part belongs to the Pulse Electronics LAN Transformers series, specifically categorized under Audio & Signal Transformers. It serves as a magnetic isolation component for high-speed digital communication interfaces. The module integrates primary and secondary windings into a compact shielded or unshielded structure suitable for consumer and industrial networking equipment.
