100B-4005T

Overview

The iNRCORE, LLC 100B-4005T is a surface mount LAN pulse transformer designed for 10/100 Base-T Ethernet applications. It features a 1:1 turns ratio and an inductance of 350µH. The component operates within a temperature range of -40°C to 85°C and is classified as non-RoHS compliant with MSL level 3 sensitivity.

Feature Summary

• Supports 10/100 Base-T data transmission standards
• Surface mount construction for automated assembly

Applications

• Ethernet network interface circuits
• LAN port signal isolation
• Telecommunications equipment

Procurement Notes

Verify RoHS compliance status prior to integration, as the component is explicitly listed as non-compliant. Confirm MSL level 3 handling requirements during storage and reflow processes. Ensure the specific suffix 'T' matches the reel packaging configuration required by the production line.

Selection Notes

Select this model specifically for 10/100 Base-T implementations requiring a 350µH inductance. For Gigabit speeds, consider the 1000B series variants instead. Verify that the physical dimensions and pinout align with the target PCB footprint design constraints.
