1000B-5002FXT

Overview

The iNRCORE 1000B-5002FXT is a surface mount LAN pulse transformer designed for 10/100/1000 Base-T applications. It features a 350µH inductance and a 1:1 turns ratio. The component measures 17.53mm in length, 12.19mm in width, and has a maximum height of 5.72mm to 5.97mm. It operates within a temperature range of -40°C to +85°C or up to +125°C depending on specific variant documentation. The unit utilizes SMD/SMT termination and is supplied in a reel package.

Feature Summary

• Supports Gigabit Ethernet data transmission standards
• Compact surface mount footprint for space-constrained designs
• Single channel configuration with integrated magnetics

Applications

• Gigabit Ethernet network interface cards
• Ethernet switch port circuits
• Industrial networking equipment

Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to confirm exact physical dimensions and thermal ratings. Ensure the reel packaging format aligns with automated assembly requirements. Confirm RoHS compliance status as historical records indicate variations across the product line. Cross-reference the distributor part number with the official iNRCORE catalog to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when a single-channel Gigabit Ethernet solution is required with a 1:1 isolation ratio. The 350µH inductance value must match the PHY transceiver specifications. Consider the 17.53mm x 12.19mm footprint constraints during PCB layout. Verify that the operating temperature range meets the environmental demands of the target application before finalizing the design.

Part Context

This device belongs to the 1000B series of LAN transformers from iNRCORE. It serves as a critical interface between the MAC layer and the physical medium. Similar models in the family include the 1000B-5001FXNL and 1000B-5003FT, which offer different channel counts or packaging options while maintaining similar electrical characteristics for Ethernet connectivity.

Replacement Considerations

The 1000B-5003FXNL and 1000B-5003FXNLT are documented parameter-equivalent alternatives from iNRCORE. These substitutes share similar electrical specifications but may differ in packaging or specific mechanical dimensions. Validate pinout compatibility and thermal performance before substitution.
