Overview
The ALAN-2204-T is a single-port LAN pulse transformer module designed for 10/100 Base-T Ethernet applications. It features a 350µH inductance and a 1CT:1CT center-tapped configuration. The component supports Power over Ethernet (PoE) and PoE+ capabilities, making it suitable for VoIP and network infrastructure. It utilizes a surface-mount package and is engineered to meet standard Ethernet isolation requirements.
Feature Summary
- Supports 10/100 Base-T Ethernet data transmission
- Integrated Power over Ethernet (PoE/PoE+) capability
- Center-tapped 1CT:1CT winding configuration
- Designed for surface-mount assembly
Applications
- VoIP phone systems
- Network interface cards
- Ethernet switches and hubs
- Industrial automation controllers
Procurement Notes
Verify the specific suffix 'T' indicates the correct tape-and-reel packaging variant if reel handling is required. Confirm that the 350µH inductance value aligns with the target PHY controller specifications. Ensure the surface-mount footprint matches the PCB layout design rules for the selected enclosure constraints.
Selection Notes
Select this component when a single-channel solution with integrated PoE support is required for 10/100 Mbps networks. It is appropriate for designs utilizing leading PHY manufacturers such as Broadcom or Marvell. Consider the center-tapped topology for common-mode noise rejection needs in noisy industrial environments.
Part Context
This part belongs to Abracon's ALAN series of LAN transformers. It serves as a critical interface between the Ethernet MAC/PHY and the physical medium connector. The module consolidates magnetics functions, reducing board space compared to discrete solutions while maintaining signal integrity standards.
Replacement Considerations
Cross-reference with other Abracon ALAN series variants for mechanical compatibility. Verify electrical equivalence with competitors like Pulse Electronics or Belden if supply chain diversification is necessary. Ensure pinout definitions match exactly before substitution.
