Overview
The HX5149NLT is a surface-mount LAN pulse transformer designed for 10/100/1000 Base-T applications. It features a 24-pin package with dimensions of 17.78mm length, 9.91mm width, and 3.20mm maximum height. The component provides a 1CT:1CT turns ratio for both transmitter and receiver circuits. Primary inductance is specified at 360µH. It supports an operating temperature range from -40°C to +85°C and offers 1500 VRMS isolation voltage.
Feature Summary
- Supports Gigabit Ethernet (10/100/1000 Base-T) data transmission standards
- Provides galvanic isolation between network lines and transceivers
- Designed for high-density surface mount assembly processes
Applications
- Gigabit Ethernet network interface cards
- Industrial communication modules requiring robust isolation
- Consumer networking hardware such as routers and switches
Procurement Notes
Verify the specific suffix 'NLT' to confirm reel packaging configuration. Ensure the selected variant matches the required 360µH inductance specification for 1000Base-T compliance. Confirm RoHS3 status and moisture sensitivity level requirements against the target manufacturing process constraints before finalizing the order.
Selection Notes
Select this component when a single-port solution for Gigabit Ethernet is required. The 24-pin SMD form factor suits space-constrained designs. Verify that the 1CT:1CT winding configuration aligns with the circuit topology. Ensure the thermal rating of +85°C meets the environmental conditions of the end application.
Part Context
This part belongs to the HX series of LAN transformers from Pulse Electronics. It serves as the non-PoE counterpart to powered variants within the same family. The component integrates magnetic components necessary for signal coupling and common-mode noise rejection in high-speed digital networks.
Replacement Considerations
The HX5149NL is the leaded through-hole equivalent of this surface-mount device. For direct pin-compatible replacements, verify datasheet specifications for identical inductance and isolation ratings. Cross-reference with other 24-pin LAN transformers if supply chain constraints require alternative sourcing.
