ALAN-2201-T

Overview

The ALAN-2201-T is a single-channel LAN signal transformer module manufactured by Abracon LLC. Designed for 10/100 Base-T Ethernet applications, it supports Power over Ethernet (PoE) functionality. The component features an operating temperature range of -40°C to +85°C and meets IEEE 802.3 specifications. Key electrical parameters include a primary inductance of 350 µH and a turn ratio of 1:1. It provides signal isolation, EMI suppression, and symmetrical transmission/reception channels for Auto MDI/MDIX capability.

Feature Summary

• Provides galvanic isolation and signal conditioning for Ethernet data lines
• Supports PoE power delivery alongside data transmission
• Ensures symmetrical TX/RX channels for automatic medium dependency interface crossover detection

Applications

• 10/100Base-T Ethernet network interfaces
• VoIP devices with PoE capabilities
• Network Interface Cards (NICs)
• Ethernet hubs, switches, and routers

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly. Confirm RoHS compliance status through official documentation. Ensure the selected variant matches the required extended temperature rating for the target environment. Cross-reference pinout diagrams with the host PCB design to guarantee correct integration.

Selection Notes

Select this component for designs requiring integrated magnetics for 10/100 Mbps Ethernet links. It is suitable for systems needing PoE support without separate common mode chokes. Consider the surface mount package dimensions for board space constraints. Verify compatibility with leading PHY IC manufacturers such as Broadcom or Marvell.

Part Context

This part belongs to Abracon's ALAN series of LAN transformers. These components are engineered to replace discrete magnetic solutions, reducing board space and assembly complexity. The series is widely used in consumer electronics and industrial networking equipment requiring reliable Ethernet connectivity.

Replacement Considerations

Check for direct substitutes from other manufacturers offering identical 1:1 turn ratios and 350 µH inductance. Ensure replacement parts meet the same IEEE 802.3 standards and physical footprint requirements.
