ALANS10002-6N41DT

Overview

The ALANS10002-6N41DT is a dual-port LAN transformer module designed for 10/100/1000BASE-T applications. It operates within a frequency range of 100 kHz to 100 MHz and features an inductance of 350 uH. The component supports primary resistance of 1.2 Ohms and secondary resistance of 900 mOhms. It functions reliably between -40°C and +85°C, with some documentation indicating compatibility up to +125°C. The physical dimensions are 27.8 mm in length, 12.8 mm in width, and 5.45 mm in height.

Feature Summary

• Compliant with IEEE 802.3ab standards for Ethernet connectivity
• Supports 10BASE-T, 100BASE-TX, and 1000BASE-T data rates
• Integrated common mode choke functionality for signal integrity

Applications

• Ethernet network interface cards
• Industrial automation controllers
• Telecommunications equipment

Procurement Notes

Verify the specific operating temperature rating required for your design, as sources indicate both +85°C and +125°C maximums. Confirm package availability in cut tape or reel formats based on production volume needs. Ensure the supplier provides the official Abracon datasheet to validate pinout and electrical characteristics against your schematic requirements before finalizing orders.

Selection Notes

Select this component when a dual-port solution is required for Gigabit Ethernet interfaces. The SMD gull-wing package facilitates automated surface mounting. Consider the thermal performance limits carefully, as conflicting data exists regarding the upper temperature boundary. Verify impedance matching requirements with the connected PHY chip to ensure signal quality.

Part Context

This part belongs to the ALANS100x1 series of LAN transformers from Abracon. These modules integrate magnetics for Ethernet ports, reducing board space compared to discrete components. The series typically includes variants for different speed ratings and port configurations, serving as critical interface elements in modern networking hardware.

Replacement Considerations

Check for direct substitutes within the ALANS100x1 family that match the specific temperature and resistance specifications. Verify pin-to-pin compatibility with existing PCB footprints before switching to alternative manufacturers.
