Fixed Inductors Procurement Notes

Verify the specific suffix '5R6M' corresponds to the required 5.6 µH value during procurement. Confirm that the package dimensions align with the target PCB footprint. Ensure the supplier provides traceability documentation consistent with automotive industry requirements. Cross-reference the manufacturer datasheet for any updates regarding RoHS compliance or material declarations before finalizing orders.

Fixed Inductors Selection Notes

Select this component when high current handling is critical due to its 40 A saturation rating. The shielded design is suitable for space-constrained applications requiring low EMI. Consider the 7.05 mOhm DCR for efficiency calculations in low-voltage, high-current paths. Verify thermal management capabilities given the wide operating temperature range up to 150°C.

Fixed Inductors Part Context
