Fixed Inductors Procurement Notes

Verify the specific suffix M000 against the manufacturer's official ordering code list to ensure correct packaging and tape specifications. Confirm that the automotive grade classification aligns with your project's quality requirements. Cross-reference the DCR and saturation current values with the latest datasheet revision to avoid discrepancies in design margins.

Fixed Inductors Selection Notes

Select this component when a compact 7x7 mm footprint is required for high-current DC-DC converters. The shielded design is critical for reducing noise coupling in sensitive automotive electronics. Ensure the thermal environment allows for the dissipation associated with the 43 mΩ resistance at the target operating current levels.

Fixed Inductors Part Context

This part belongs to the B82472D6 series of SMT power inductors. These components are engineered for tight coupling factors in SEPIC and ZETA topologies. The series provides a balance of low DC resistance and high current handling within a standardized package size for automotive power stages.

Fixed Inductors Replacement Considerations

Compatible substitutes include other B82472D6 variants with different inductance values, such as B82472D6222M000 or B82472D6472M000, provided the electrical parameters match the circuit requirements.
