TG46-S020NXLFTR

Pulse Transformers Overview

The TG46-S020NXLFTR is a LAN 10 Base-T pulse transformer manufactured by HALO Electronics, Inc. It features a surface mount design with a transmitter ratio of 1CT:1.41CT and a receiver ratio of 1:1. The component has an inductance of 140µH and a maximum DC resistance of 400 mOhms. It is supplied in a tape and reel package.

Pulse Transformers Feature Summary

• Surface mount isolation module for LAN applications
• Integrated transmitter and receiver winding configurations
• Designed for 10 Base-T signal transmission

Pulse Transformers Applications

• 10 Base-T network interface circuits
• LAN data line isolation
• Ethernet signal coupling modules

Pulse Transformers Procurement Notes

Verify the specific suffix LFTR indicates tape and reel packaging when sourcing. Confirm that the 1CT:1.41CT transmitter and 1:1 receiver ratios match the target circuit requirements. Ensure the 140µH inductance specification aligns with the 10 Base-T standard compliance needs of the design.

Pulse Transformers Selection Notes

Select this component for designs requiring dedicated 10 Base-T pulse transformation with surface mount constraints. The 1CT:1.41CT primary configuration supports specific impedance matching requirements for the transmitter side. Verify compatibility with the 400 mOhms maximum DC resistance limit for power efficiency considerations.

Pulse Transformers Part Context

This part belongs to the HALO Electronics audio and signal transformers category, specifically within the LAN isolation modules sub-series. It serves as a passive magnetic component for Ethernet physical layer interfaces, distinct from general-purpose audio transformers or high-voltage isolation devices.

Pulse Transformers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other HALO Electronics 10 Base-T SMD modules such as the TG41 series if pinout and electrical parameters allow.
