100B-1003FXT

Overview

The iNRCORE 100B-1003FXT is a single-port LAN pulse transformer designed for surface mount technology (SMT) applications. It supports 10/100 Base-T Ethernet standards with a 1:1 turns ratio. Key electrical specifications include an inductance of 350 µH and an insulation voltage rating of 1500 Vrms. The component operates within a temperature range of -40°C to +85°C. It is supplied in a reel package format, facilitating automated assembly processes for network interface circuits.

Feature Summary

• Provides signal isolation and impedance matching for 10/100 Base-T Ethernet connections
• Engineered for surface mount integration into printed circuit boards
• Ensures galvanic isolation between network lines and transceiver components

Applications

• Ethernet network interface cards
• Computer motherboard LAN ports
• Network switch internal circuitry

Procurement Notes

Verify the specific suffix 'FXT' against official iNRCORE documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with existing PCB footprint designs before procurement. Cross-reference datasheet parameters such as inductance and insulation ratings with system requirements to guarantee operational integrity.

Selection Notes

Select this component for designs requiring standard 10/100 Base-T isolation without Gigabit capabilities. Confirm that the SMT package dimensions align with available board space. Evaluate thermal performance within the specified operating range to ensure reliability under continuous network traffic loads.

Part Context

This part belongs to the iNRCORE LAN transformer series, specifically tailored for basic Ethernet connectivity. It serves as a critical passive component in network hardware, distinguishing itself from higher-speed variants by supporting only 10 and 100 Mbps data rates. The module integrates primary and secondary windings for efficient signal transmission.

Replacement Considerations

Direct substitutes may include other iNRCORE single-port 10/100 Base-T transformers with identical pinouts and 350 µH inductance. Verify mechanical compatibility and electrical equivalence before swapping. Consult manufacturer cross-reference lists for approved alternative part numbers.
