Fixed Inductors Procurement Notes

Verify part authenticity through authorized Coilcraft distributors or direct manufacturer channels. Confirm that the specific suffix MEC matches the required termination material and packaging format. Ensure compliance with RoHS and halogen-free standards as specified in the official datasheet. Cross-reference the AEC-Q200 certification status if automotive grade validation is critical for the application.

Fixed Inductors Selection Notes

Select this component when low DC resistance and high current capability are required in a compact 1616 package. The soft saturation profile makes it suitable for applications experiencing current spikes. Verify that the 330 nH value aligns with the target switching frequency and ripple current requirements. Consider the thermal performance limits relative to the ambient operating environment.

Fixed Inductors Part Context

This model belongs to the XEL series of shielded power inductors manufactured by Coilcraft. The series is characterized by composite cores and molded packages designed for robust performance in demanding environments. The XEL4020 variant specifically targets automotive electronics requiring high efficiency and low acoustic noise.

Fixed Inductors Replacement Considerations

Consult official Coilcraft documentation for verified substitute part numbers within the XEL series or other compatible families. Do not assume interchangeability based on similar electrical parameters alone; verify mechanical footprint and thermal characteristics.
