Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm that the 4.5A current rating and 20mOhm DCR align with your circuit requirements. Ensure the 1206 footprint matches your PCB layout. Check for AEC-Q200 compliance if automotive certification is mandatory for your project specifications.

Selection Notes

Select this component when high current capacity is required alongside EMI filtering in space-constrained designs. The shielded design reduces magnetic field leakage compared to unshielded alternatives. Consider the 1206 package size for standard SMT assembly processes. Evaluate the 100-ohm impedance at the target noise frequency to ensure effective attenuation without excessive voltage drop.

Part Context

This part belongs to the ABUP series, which focuses on high-current ferrite beads for demanding applications. The series utilizes Chilisin technology for consistent performance. The ABUP line is specifically engineered to handle significant DC currents while maintaining effective noise suppression characteristics in compact surface-mount packages suitable for modern electronic assemblies.

Replacement Considerations

Cross-reference with other ABUP series variants for different impedance or current ratings. Verify package compatibility with existing footprints. Ensure substitute parts meet the same AEC-Q200 automotive standards and thermal operating ranges.
