H2017NL

Overview

The H2017NL is a surface-mount audio and signal transformer manufactured by Pulse Electronics. Designed for 100Base-TX applications, this component integrates Power over Ethernet (PoE) capabilities within a quad-port configuration. It features an inductance of 350uH and a DC resistance of 0.65 Ohms. The device utilizes transfer mold construction to ensure durability in demanding environments. As a LAN and Ethernet transformer/choke, it supports high-speed data transmission while managing power delivery requirements for connected network devices.

Feature Summary

• Integrates PoE functionality with 100Base-TX Ethernet signaling
• Quad-port design for multi-device connectivity
• Transfer mold construction for environmental protection

Applications

• 100Base-TX network interface circuits
• Power over Ethernet powered devices
• LAN and Ethernet infrastructure equipment

Procurement Notes

Verify the specific datasheet version and mechanical dimensions before finalizing the PCB layout. Confirm that the quad-port configuration matches the target circuit design requirements. Ensure compatibility with the intended manufacturing process for surface-mount assembly. Check for any recent updates to the RoHS or REACH compliance status directly from the manufacturer's official documentation prior to ordering.

Selection Notes

Select this component when a combined Ethernet isolation and PoE solution is required for 100Base-TX networks. The quad-port architecture simplifies board space usage compared to discrete solutions. Consider the 350uH inductance value for appropriate common-mode noise rejection. Evaluate the 0.65 Ohm DC resistance against the power budget constraints of the application.

Part Context

This part belongs to the Pulse Electronics lineup of audio and signal transformers. It falls under the category of isolation and data interface components specifically engineered for LAN and Ethernet applications. The product serves as a critical interface between the physical layer transceiver and the external network medium, providing necessary galvanic isolation and signal integrity management.

Replacement Considerations

Consult official distributor databases for cross-reference information. Verify pinout compatibility and electrical specifications such as inductance and DC resistance before substituting. Ensure the replacement maintains the same quad-port PoE capability and 100Base-TX rating.
