ALAN-508-T

Overview

The ALAN-508-T is a surface mount pulse transformer designed for 10/100 Base-T LAN applications. It features a 1CT:1CT turns ratio and an inductance of 350µH. The component supports PoE Extended Temperature operation and operates within a temperature range of -40°C to 85°C. Its physical dimensions are 12.70mm x 8.80mm with a maximum height of 5.95mm. The device utilizes a tube packaging format.

Feature Summary

• Supports 10/100 Base-T single port LAN connectivity
• Integrated PoE extended temperature capability
• Surface mount package design

Applications

• 10/100 Base-T network interface circuits
• PoE enabled Ethernet devices
• LAN transformer modules

Procurement Notes

Verify the specific suffix designation when ordering, as the base model ALAN-508 typically uses tube packaging while the ALAN-508-T variant indicates tape and reel configuration. Confirm that the required inductance value of 350µH and the 1CT:1CT turns ratio align with the target circuit design specifications before finalizing procurement.

Selection Notes

Select this component for designs requiring standard 10/100 Mbps Ethernet isolation with PoE support. Ensure the surface mount footprint matches the PCB layout constraints defined by the 12.70mm x 8.80mm outline. Verify thermal management requirements against the specified -40°C to 85°C operating range.

Part Context

This part belongs to Abracon's LAN transformer portfolio, specifically engineered for Ethernet physical layer interfaces. It serves as a critical isolation component between the MAC and PHY layers in networking hardware, providing signal coupling and impedance matching for compliant data transmission.

Replacement Considerations

Public confirmed substitute part numbers include ALAN-508, ALAN-2201, and ALAN-2202. Verify pinout compatibility and electrical parameter equivalence before substitution.
