100B-1003F

Overview

The iNRCORE 100B-1003F is a surface-mount pulse transformer designed for LAN applications supporting 10/100 Base-T standards. 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 has a maximum installation height of 0.341 inches (8.66mm). Dimensions are 1.100 inches long by 0.297 inches wide.

Feature Summary

Supports 10/100 Base-T LAN transmission standards
Surface mount package design for automated assembly
High reliability magnetic component construction

Applications

Ethernet network interface circuits
LAN port signal isolation
Telecommunications equipment

Procurement Notes

Verify the specific suffix designation, as variants such as 100B-1003FNL or 100B-1003X exist with potentially different packaging or compliance statuses. Confirm moisture sensitivity level (MSL) requirements for your manufacturing process, as some related models are MSL 3. Ensure the selected variant matches the required RoHS or REACH compliance status for your target market regulations.

Selection Notes

Select this component when designing for 10/100 Mbps Ethernet connectivity requiring a single-channel pulse transformer. Consider the physical footprint constraints against the 1.100 x 0.297 inch dimensions. Verify that the 350µH inductance meets the impedance matching requirements of your specific PHY chip. Check for alternative suffixes if lead-free or specific tape-and-reel quantities are mandatory.

Part Context

This part belongs to the iNRCORE EXTMP series of high-reliability magnetic components. The manufacturer specializes in power inductors and transformers for harsh environments. This specific model addresses the need for compact, surface-mount solutions in legacy and standard-speed networking hardware where space efficiency is critical.

Replacement Considerations

The 100B-1003FXNL and 100B-1003FXNLT are documented parameter-equivalent substitutes from iNRCORE. These alternatives offer identical electrical characteristics but may differ in packaging format or compliance certifications. Verify mechanical compatibility before substitution.
