Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging configuration. Confirm that the required impedance value matches the specific application frequency requirements. Check RoHS compliance status against current regulatory standards. Ensure the maximum DC current rating exceeds the operational load to prevent performance degradation. Validate the package dimensions against the target PCB footprint.

Selection Notes

Select this component when a low-profile ferrite bead is required for high-density layouts. The 0402 package size allows for space-constrained designs. Consider the 80-ohm impedance profile for targeting specific noise frequencies around 100 MHz. Evaluate the 200 mA current rating against the circuit's steady-state and peak current demands. Compare the DC resistance impact on power integrity relative to alternative components.

Part Context

This component belongs to the ACML series of multilayer ferrite chip beads from Abracon. The series offers various impedance values and current ratings within standard industrial packages. These components are engineered for electromagnetic interference suppression in portable and stationary electronics. The ACML-0402 variant specifically addresses miniaturization needs in modern circuit board designs.

Replacement Considerations

Direct substitutes include other 0402 ferrite beads with 80 ohms impedance at 100 MHz and similar current ratings. Verify pin compatibility and thermal characteristics before substitution. Cross-reference datasheets for impedance curves to ensure equivalent noise suppression performance across the target frequency spectrum.
