Fixed Inductors Procurement Notes

Verify the specific suffix 'MEC' against official Coilcraft documentation to confirm termination plating and packaging specifications. Ensure the selected variant matches the required thermal derating curves and AEC-Q200 compliance status for the target application environment.

Fixed Inductors Selection Notes

Select this component based on the required 1.8 µH inductance and 21 A RMS current capability. Consider the 4.46 mΩ DCR for conduction loss calculations. Verify that the 25 A saturation limit accommodates peak load transients without performance degradation in the circuit design.

Fixed Inductors Part Context

This part belongs to the XAL7070 series of shielded power inductors designed for high-current applications. The series offers various inductance values while maintaining consistent footprint dimensions. The XAL7070 line is engineered for robustness in demanding environments, particularly within automotive systems requiring strict reliability standards.

Fixed Inductors Replacement Considerations

Consult the official Coilcraft XAL7070 datasheet for cross-reference options. Substitutes must match the 7.5x7.2x7 mm package, 1.8 µH value, and ≥21 A current ratings. Verify equivalent AEC-Q200 certification if automotive use is required.
