• Integrates Power over Ethernet Plus functionality up to 30 Watts
• Includes built-in common mode choke for signal integrity
• Complies with IEEE 802.3at standards

Applications

• Gigabit Ethernet network interfaces
• Power over Ethernet powered devices
• Industrial networking equipment
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix 'JT' against the manufacturer's official datasheet to confirm pinout configuration and RoHS compliance status. Ensure the selected variant matches the required thermal operating range of -40°C to +105°C for the intended application environment. Cross-reference the package dimensions with the PCB footprint design to guarantee mechanical compatibility during assembly.

Selection Notes

Select this component for designs requiring integrated isolation and common mode filtering in a compact surface mount form factor. The 350 µH inductance value ensures adequate performance for high-speed data transmission. Consider the 600 mA current rating when designing power delivery circuits to ensure the transformer can handle the maximum load without saturation or excessive heating under PoE+ conditions.

Part Context

This part belongs to the ALANS series of LAN transformers from Abracon LLC. These modules are engineered to replace discrete transformer and choke components, reducing board space and simplifying assembly. The series is widely used in modern networking hardware where reliable signal integrity and power delivery are critical requirements for stable operation.

Replacement Considerations

Public confirmed substitute part numbers include ALANS10001-3J61ET and ALANS10001-3J11JT. Verify that any replacement maintains the same 1CT:1CT turns ratio and 350 µH inductance specifications. Ensure the alternative component supports the same 10/100/1000 Base-T speed ratings and PoE+ power levels before implementation.
