Procurement Notes
Verify component status as the specific variant ACM4520V-901-2P-T00 may be listed as Not Recommended for New Designs (NRND) by some distributors. Confirm availability through authorized channels and check for active stock or last-time buy notices before finalizing procurement plans.
Selection Notes
Select this component when automotive-grade common mode chokes are required with high current handling capabilities. Ensure the 1.2 A rating meets circuit requirements and verify that the 60 mΩ DC resistance aligns with power loss constraints. The shielded design is critical for applications demanding strict EMI compliance.
Part Context
This part belongs to the ACM-V series of common mode chokes designed for automotive applications. It utilizes a wire-wound technology on a ferrite core, offering robust performance in noisy environments. The series is characterized by its compact footprint and high reliability under automotive operating conditions.
Replacement Considerations
Check for direct substitutes within the ACM4520V series with matching impedance and current ratings. Consider ACM4520V-142-2P-T00 if higher impedance is acceptable, but verify differences in DC resistance and current capacity.
