Fixed Inductors Procurement Notes

Verify the specific suffix codes against official Murata documentation to confirm exact tolerance and packaging specifications. Ensure that the selected variant meets the required automotive reliability standards if used in vehicle electronics. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a low-inductance value is required for high-frequency RF applications. The 0402 footprint allows for dense PCB layouts. Consider the 350 mA current rating and 460 mOhm DCR for power handling requirements. The unshielded nature may require careful layout consideration to minimize electromagnetic interference with adjacent components in sensitive designs.
