Fixed Inductors Procurement Notes

Verify the specific suffix 'H' corresponds to the required automotive grade and RoHS compliance status. Confirm that the 1616 package dimensions align with the target PCB land pattern. Ensure the saturation current rating meets the peak load requirements of the intended circuit application before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when a compact shielded inductor is required for automotive or high-reliability environments. The 3.3 µH value suits moderate frequency switching applications. Compare the 2.40 A saturation current against the system's maximum ripple current to ensure stable operation without magnetic saturation during peak loads.

Fixed Inductors Part Context

This part belongs to the VLS-CX-H series, which focuses on high-power density and low-profile designs. The series utilizes ferrite cores to achieve efficient magnetic shielding. The VLS4015CX-3R3M-H specifically targets applications requiring robust performance in small form factors while maintaining strict automotive quality standards.

Fixed Inductors Replacement Considerations

Direct substitutes include other VLS4015CX variants with identical inductance and current ratings. Verify package compatibility and thermal characteristics when considering alternative manufacturers. Cross-reference AEC-Q200 certification if automotive usage is mandatory.
