1000B-5003FNLT

Overview

The iNRCORE 1000B-5003FNLT is a LAN pulse transformer designed for 10/100/1000 Base-T applications. It features a 1:1 turns ratio and an inductance of 350µH. The component utilizes a surface mount gull wing package with 50 terminals, measuring 27.94mm in length, 7.54mm in width, and 8.66mm in height. It operates within a temperature range of -40°C to 85°C and carries Moisture Sensitivity Level 3 classification.

Feature Summary

• Supports Gigabit Ethernet data transmission standards
• Dual isolated configuration for signal integrity
• Surface mount construction for automated assembly

Applications

• 10/100/1000 Base-T network interface cards
• Ethernet switch port circuits
• Network hub internal modules

Procurement Notes

Verify RoHS compliance status as sources indicate conflicting lead-free and non-compliant designations. Confirm the specific suffix variant matches the required packaging format. Ensure storage conditions address the MSL 3 rating to prevent moisture damage prior to soldering.

Selection Notes

Select this component for high-density PCB layouts requiring integrated isolation. The 50-terminal gull wing footprint accommodates complex pinout requirements. Verify thermal limits against the operating environment constraints before integration into the final network hardware design.

Part Context

This part belongs to the 1000B series of telecom transformers manufactured by iNRCORE. It serves as a critical passive element in modern networking infrastructure, providing necessary impedance matching and common-mode rejection for reliable high-speed data communication over copper cabling.

Replacement Considerations

The 1000B-5003FT is a parameter-equivalent alternative from the same manufacturer. Cross-reference terminal configurations and physical dimensions to ensure mechanical compatibility during substitution.
