HX7019NL

Overview

The HX7019NL is a board-mount power transformer manufactured by Pulse Electronics. It is designed for MDL (Modular Data Link) applications supporting 10G speeds with a 1:1 turns ratio. The component utilizes surface mount technology and features a single input to single output configuration. It belongs to the GEN2 series and includes an integrated shielded core structure. The device is RoHS compliant and available in tube packaging.

Feature Summary

• Supports 10G data transmission rates for high-speed network interfaces
• Integrates a shielded magnetic core to minimize electromagnetic interference
• Designed for direct board mounting via surface mount termination

Applications

• 10 Gigabit Ethernet network interface cards
• Server and switch motherboard connectivity modules
• High-speed data communication equipment requiring isolated signal coupling

Procurement Notes

Verify that the specific order matches the HX7019NL part number rather than the reel variant HX7019NLT, as packaging differs. Confirm RoHS compliance status through official documentation prior to integration. Ensure surface mount footprint compatibility with the target PCB design. Validate that the 10G speed rating meets system requirements. Check for any recent revision changes in the manufacturer datasheet.

Selection Notes

Select this component when a 1:1 isolation transformer is required for 10G signaling paths. The surface mount package facilitates automated assembly processes. Consider the integrated shielding if EMI constraints are strict within the enclosure. Verify that the single-channel configuration aligns with the differential pair layout of the application circuit.

Part Context

This transformer is part of Pulse Electronics' HX series, which focuses on modular data link solutions. The series supports various Ethernet standards including 10GBASE-T. The HX7019NL specifically targets general-purpose 10G applications with standard impedance matching. It complements other components in the same family offering different pin counts or ratios.

Replacement Considerations

The HX7019NLT serves as a functional equivalent differing primarily in packaging format. Both parts share identical electrical characteristics and magnetic specifications. Substitution requires verification of the reflow profile compatibility with the alternative tape-and-reel format. Ensure the mechanical height constraints allow for the selected packaging option.
