Fixed Inductors Procurement Notes

Verify the specific suffix against official Bourns documentation to confirm exact electrical ratings and packaging options. Ensure that the selected variant matches the required saturation and RMS current specifications for the target application. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when high current handling and compact SMD footprint are required for automotive-grade designs. Compare the 5.5 A saturation limit against peak load requirements to prevent inductance collapse. Consider the 44.1 mΩ DCR for efficiency calculations in low-voltage power stages. Verify thermal management capabilities given the wide operating temperature range.
