Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct tolerance and packaging configuration. Confirm that the selected variant meets the required AEC-Q200 qualification if used in automotive contexts. Cross-reference the DigiKey part number 732-1726-1-ND or equivalent distributor identifiers to validate stock availability and exact reel specifications before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 12 nH is required for high-frequency signal paths. The unshielded construction necessitates careful PCB layout to minimize electromagnetic interference with adjacent traces. Ensure the operating environment remains within the specified -40°C to 125°C range and that the circuit current does not exceed the 640 mA rating to maintain performance stability.

Fixed Inductors Part Context

This inductor belongs to the WE-KI series by Würth Elektronik, which specializes in ceramic wirewound RF inductors. These components are designed for applications requiring high Q factors and superior self-resonant frequencies. The 0402 footprint allows for compact integration into modern surface-mount assemblies, particularly where space constraints limit the use of larger inductive components.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include the 744765113A (13 nH) and 744765019A (1.9 nH). Verify that alternative part numbers match the required inductance tolerance and current ratings. Any replacement must maintain the 0402 package dimensions and AEC-Q200 qualification if automotive compliance is mandatory.
