Fixed Inductors Procurement Notes

Verify the specific suffix V2 against design requirements to ensure compatibility with target voltage and current profiles. Confirm that the 4 A saturation limit aligns with peak load conditions. Check AEC-Q200 certification status if strict automotive compliance is mandated. Validate footprint dimensions against PCB layout constraints prior to finalization.

Fixed Inductors Selection Notes

Select this model when space-constrained automotive designs require a shielded inductor with moderate inductance values. The 3.3 uH rating suits filtering applications where low impedance is critical. Consider the 9 mOhms DCR for efficiency optimization in low-voltage rails. Ensure the 4 A saturation current meets transient load demands without magnetic collapse.

Fixed Inductors Part Context

This component belongs to the HCM1AV2 series of high-power surface-mount inductors. The series targets automotive markets with robust shielding and high current capabilities. The V2 designation indicates specific manufacturing revisions within the HCM1A family. It complements other variants offering different inductance and current ratings within the same physical envelope.

Fixed Inductors Replacement Considerations

Direct substitutes include HCM1A4020V2-R33-R and HCM1A4020V2-R47-R from the same manufacturer. Cross-model comparisons should verify identical footprint and pinout configurations. Alternative brands may offer similar specifications but require validation of AEC-Q200 compliance and thermal characteristics.
