Procurement Notes
Verify the specific part number ACM-31-161M-T against official Abracon documentation to ensure accuracy. Confirm that the required electrical parameters, including the 160 Ohm impedance and 340 mA current rating, align with the design specifications. Check for compliance with RoHS3 regulations and confirm the surface-mount package dimensions match the board layout requirements before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring common mode noise filtration for signal lines with currents up to 340 mA. Ensure the operating environment stays within the specified -40°C to 85°C temperature range. Consider the 400 milliohm DCR limit for power loss calculations. Verify that the 160 Ohm impedance at 100 MHz meets the target frequency attenuation needs for the application.
Part Context
This component belongs to the ACM-31 series of chip wire-wound common mode chokes from Abracon Corporation. The series offers various impedance and current ratings tailored for different signal line protection requirements. These components are engineered for high reliability in surface-mount assemblies, providing consistent performance across industrial and commercial electronics applications.
Replacement Considerations
Compatible substitutes within the same series include ACM-31-121M-T and ACM-31-261M-T. Verify that alternative part numbers meet the specific impedance and current requirements of the circuit before substitution.
