H1086NL

Overview

The H1086NL is a single-port LAN pulse transformer module manufactured by Pulse Electronics, designed for 10/100Base-T applications. It features a surface-mount package with dimensions of 25.40 mm length, 9.91 mm width, and a maximum height of 6.22 mm. The component operates within a temperature range of 0°C to 70°C and supports a 1:1 turns ratio. It is RoHS compliant and compatible with transceivers from Broadcom, Intel, Micrel, National Semiconductor, ICS, and TDK.

Feature Summary

• Supports 10/100Base-T Ethernet transmission standards
• Surface-mount design for automated assembly
• Compatible with major transceiver manufacturers

Applications

• 10/100 Base-T network interface cards
• Ethernet switch ports
• Network hub implementations

Procurement Notes

Verify the specific suffix (e.g., NLT vs NL) to confirm packaging type, as tape-and-reel variants may differ in handling requirements. Confirm moisture sensitivity level compliance before reflow soldering. Ensure the selected variant matches the required turns ratio and isolation voltage specifications for the target circuit design.

Selection Notes

Select this component for standard 10/100 Mbps Ethernet interfaces requiring non-PoE solutions. Verify compatibility with the specific PHY transceiver used in the design, particularly regarding impedance matching and common-mode choke integration. Consider thermal management within the 0°C to 70°C operating range.

Part Context

This part belongs to Pulse Electronics' series of 10/100 Base-T single-port transformer modules. It shares functional similarities with models like H1012NL and HX1148NL but differs in specific electrical parameters and packaging options. These modules are integral components for isolating and coupling Ethernet signals in networking hardware.

Replacement Considerations

H1012NL and HX1148NL are documented alternatives within the same product family. Verify pinout compatibility and electrical specifications before substitution.
