Procurement Notes

Verify the specific manufacturer lifecycle status before procurement, as availability may vary across distributors. Confirm that the unshielded configuration aligns with electromagnetic interference requirements for the target application. Ensure the operating temperature range meets environmental specifications. Validate the physical footprint dimensions against the printed circuit board layout constraints prior to ordering.

Selection Notes

Select this component when a 390 nH inductance value is required with tight 3% tolerance. Consider the 475 mA current rating and 450 mOhm resistance for power handling needs. The unshielded nature requires careful placement to avoid coupling issues. Verify compatibility with standard SMT assembly processes and ensure the package dimensions fit the designated board space.
