23Z467SMNLT

Overview

The Pulse Electronics 23Z467SMNLT is a surface-mount LAN isolation transformer designed for 10Base-T applications. It features a primary inductance of 140µH and a DC resistance of 0.6 Ohms. The component utilizes a 1CT:2CT turns ratio for the transmitter and 1CT:1CT for the receiver. It operates within a temperature range of 0°C to 70°C and measures 11.43mm x 6.73mm with a maximum height of 5.46mm.

Feature Summary

• Provides galvanic isolation for 10Base-T Ethernet signals
• Optimized for single-port network adapter integration
• Non-PoE compliant design suitable for standard data transmission

Applications

• Ethernet Network Interface Cards (NICs)
• Motherboard LAN ports
• Media Access Units (MAUs)

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm moisture sensitivity level (MSL 3) handling requirements during assembly. Ensure the specific suffix 'NLT' matches the reel packaging requirement rather than tube packaging found in similar part numbers like 23Z467SM.

Selection Notes

Select this component specifically for 10Base-T legacy systems requiring 140µH inductance. Verify that the 0.6 Ohm DC resistance meets the power budget constraints of the target circuit. Ensure the 16-terminal gull-wing package fits the available PCB footprint dimensions of 11.43mm by 6.73mm.

Part Context

This component belongs to Pulse Electronics' LAN Isolation Transformer series, which supports various Ethernet standards including 10Base-T and 1000Base-T. The 23Z467SMNLT variant is distinct from higher-speed models like the H5077NLT due to its specific 10Base-T optimization and lower inductance values.

Replacement Considerations

Direct substitutes include other 10Base-T transformers with identical 140µH inductance and 1CT:2CT/1CT:1CT ratios. Verify pinout compatibility for the 16-terminal SMD package before substitution.
