H5149NL

Overview

The H5149NL is a single-port surface mount pulse transformer designed for 10/100/1000 Base-T LAN applications. It supports non-PoE configurations with a 1CT:1CT transmitter and 1CT:1CT receiver topology. The component features an inductance range of 300µH to 360µH and utilizes a gull-wing SMD package measuring 17.8mm x 9.9mm x 3.2mm. It is constructed for PCMCIA form factor integration, providing signal isolation and impedance matching for Gigabit Ethernet interfaces without power-over-Ethernet capabilities.

Feature Summary

• Supports 10/100/1000 Base-T data rates
• Non-PoE signal isolation design
• Gull-wing surface mount termination

Applications

• Gigabit Ethernet network interface cards
• PCMCIA LAN adapters
• Industrial communication gateways

Procurement Notes

Verify the specific datasheet version for the H5149NL to confirm RoHS compliance status and detailed electrical tolerances. Ensure the selected variant matches the required non-PoE specification. Cross-reference the physical dimensions against the PCB footprint to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component when a single-port solution for Gigabit Ethernet is required without PoE functionality. The 1CT:1CT winding configuration is suitable for standard differential signaling. Verify that the operating temperature range meets the environmental requirements of the target application before finalizing the design.

Part Context

Pulse Electronics manufactures the H5149NL as part of its LAN transformer portfolio. This series provides isolated coupling for high-speed data transmission. The component is distinct from PoE-enabled variants, focusing solely on signal integrity for 1000Base-T standards.

Replacement Considerations

Consult official substitution lists for direct equivalents. Generic replacements may differ in inductance or DC resistance specifications.
