TG46-S020NXRLTR

Pulse Transformers Overview

The TG46-S020NXRLTR is a LAN isolation transformer module from HALO Electronics, designed for 10BASE-T applications. It features a surface-mount SMD-40 package with dimensions of 27.94 mm length, 12.19 mm width, and 5.84 mm height. The component provides quad channel isolation with an inductance of 140 uH and a maximum DC resistance of 400 mOhms. It supports an insulation voltage of 1.5 kV and operates within a temperature range of 0°C to +70°C. The turns ratio is specified as 1CT:1.41CT for the transmitter and 1:1 for the receiver.

Pulse Transformers Feature Summary

• Integrated common mode choke for enhanced noise rejection
• Shielded construction to minimize electromagnetic interference
• Surface-mount design optimized for automated assembly

Pulse Transformers Applications

• 10BASE-T Ethernet network interface circuits
• LAN port signal isolation
• Digital audio line balancing systems

Pulse Transformers Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compatibility with the intended circuit topology. Confirm that the surface-mount footprint matches the PCB layout requirements. Check for RoHS compliance status if environmental regulations apply to the final product assembly. Ensure the operating temperature range aligns with the system's thermal environment.

Pulse Transformers Selection Notes

Select this component when a quad-port isolation solution with integrated common mode filtering is required for 10BASE-T standards. The 140 uH inductance value suits standard gigabit and 10-megabit Ethernet signaling frequencies. Consider the SMD-40 package size for space-constrained designs requiring robust galvanic isolation between the PHY and the magnetics.

Pulse Transformers Part Context

This part belongs to the TG-10BT series of LAN isolation transformers manufactured by HALO Electronics. It is functionally similar to the TG44-S020NXRLTR but includes an additional common mode choke feature. The series offers various configurations for different Ethernet speeds and power over Ethernet requirements.

Pulse Transformers Replacement Considerations

The TG44-S020NXRLTR is a related variant within the same series. Verify if the absence of the integrated common mode choke in the TG44 model meets the specific EMI requirements of the application before substitution.
