23Z467SM-T

Overview

The Pulse Electronics 23Z467SM-T is a surface mount LAN isolation transformer designed for 10G Base-T applications. It features an inductance of 140µH with a turns ratio of 1CT:2CT for the transmitter and 1CT:1CT for the receiver. The component measures 11.43mm x 6.73mm with a maximum seated height of 5.46mm. It operates within a temperature range of 0°C to 70°C and has a minimum operating frequency of 100 kHz.

Feature Summary

• Provides galvanic isolation for high-speed data transmission lines
• Optimized magnetic coupling for 10G Base-T signal integrity
• Compact surface mount footprint for automated assembly

Applications

• 10G Base-T network interface cards
• Ethernet hubs and switches
• Motherboard integrated LAN ports

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging, distinct from the tube-packaged '23Z467SM'. Confirm RoHS compliance status as some variants may not meet current environmental standards. Ensure the supplier provides official datasheets matching the manufacturer's part number to avoid counterfeit components.

Selection Notes

Select this component when designing for 10G Base-T Ethernet standards requiring specific 1CT:2CT transmitter ratios. Compare physical dimensions against board space constraints. Verify thermal performance within the 0°C to 70°C operational range for the target environment.

Part Context

This part belongs to Pulse Electronics' LAN isolation transformer series, specifically engineered for Ethernet connectivity. It serves as a critical interface between the PHY chip and the RJ45 connector, ensuring signal quality and electrical safety in modern networking hardware.

Replacement Considerations

Check for direct substitutes with identical 140µH inductance and 1CT:2CT/1CT:1CT ratios. Ensure replacement parts match the 11.43mm x 6.73mm footprint and 5.46mm height limits for mechanical compatibility.
