Overview
The ALAN210001-3J61DT is a shielded LAN transformer from Abracon, designed for 10/100/1000 Base-T Ethernet applications with Power over Ethernet Plus (PoE+) support. It features a single-port configuration with a 1CT:1CT turns ratio and an inductance of 350 µH. The component has a power rating of 30 W, primary resistance of 1.2 Ohms, and secondary resistance of 1 Ohm. Operating temperature ranges from -40°C to 85°C. Dimensions are 18.3 mm x 12.4 mm x 6.4 mm, utilizing SMD/SMT termination.
Feature Summary
- Supports 10/100/1000 Base-T data rates with integrated PoE+ capability
- Shielded construction for enhanced electromagnetic interference protection
- Single-port design optimized for compact network interface implementations
Applications
- Gigabit Ethernet network interfaces
- PoE+ powered device integration
- Industrial networking equipment
- Consumer electronics with Ethernet connectivity
Procurement Notes
Verify the specific suffix 'DT' against official Abracon documentation to confirm tape-and-reel packaging and moisture sensitivity level requirements. Ensure compatibility with reflow soldering profiles specified in the datasheet. Cross-reference pinout assignments with target PCB layout to prevent installation errors during surface-mount assembly processes.
Selection Notes
Select this component when PoE+ power delivery is required alongside Gigabit data transmission in space-constrained designs. The 30 W power rating supports standard PoE+ classifications. Verify thermal management needs given the 85°C upper operating limit. Confirm that the 1.2 Ohm primary resistance aligns with system loss budgets for efficient power transfer.
Part Context
Part of the ALAN210001 series, this transformer integrates magnetics for Ethernet PHY connections. It replaces discrete components by combining common mode chokes and center-tapped transformers into a single SMD package. The design simplifies board layout while maintaining signal integrity for high-speed data lines in modern networking hardware.
Replacement Considerations
Check for direct substitutes within the ALAN210001 family such as ALAN210001-3JC0JT or ALAN210001-3J61ET. Verify identical pinout, inductance values, and PoE+ ratings before substitution. Ensure replacement parts meet the same environmental and electrical specifications for seamless integration.
