Procurement Notes

Verify the specific suffix designation (e.g., K vs F) against the manufacturer's official documentation to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status as indicated in the datasheet, noting that some listings may indicate non-compliance or lack of information. Cross-reference the part number with authorized distributors to validate current availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when an unshielded RF inductor with 120 nH inductance and 1% tolerance is required. Ensure the application current does not exceed 710 mA and that the operating frequency remains below the 400 MHz self-resonant limit. Verify that the 3.94 x 2.79 mm footprint fits the target PCB layout constraints.
