Fixed Inductors Procurement Notes

Verify compliance status prior to procurement as lead records indicate this specific part number may be non-RoHS compliant. Confirm the manufacturer's current production status and datasheet version to ensure alignment with project requirements. Cross-reference the ordering suffix to validate the exact tolerance code specified for the design.

Fixed Inductors Selection Notes

Select this component for designs requiring low inductance values in a compact 0402 footprint. The high self-resonant frequency makes it suitable for RF applications. Ensure the circuit current does not exceed the 0.76 A limit. Verify thermal management capabilities given the 125 °C maximum operating temperature specification.
