Procurement Notes
Verify the specific manufacturer part number against official Abracon documentation to ensure accuracy. Confirm that the required impedance, current rating, and package dimensions align with the design specifications before procurement. Check for RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this component when a low-profile, two-line filter is required for differential or single-ended signal lines. Ensure the operating current does not exceed the rated limit to prevent saturation. Verify that the impedance characteristic at the target frequency meets the noise attenuation requirements of the circuit.
Part Context
This component belongs to the ACM-21 series of chip wire wound common mode chokes from Abracon. The series offers various impedance and current ratings in a standardized small footprint, suitable for integration into modern electronic systems requiring efficient electromagnetic interference mitigation.
Replacement Considerations
Consult official Abracon documentation for verified substitute part numbers within the ACM-21 series or other compatible families. Ensure any replacement matches the electrical parameters and physical dimensions to maintain board compatibility.
