Procurement Notes

Verify component status carefully as this part is scheduled for obsolescence. Confirm availability through authorized distributors before finalizing designs. Check for end-of-life notices or last-time-buy dates. Ensure RoHS compliance documentation is available if required for specific regulatory standards. Validate pinout and footprint compatibility during procurement planning.

Selection Notes

Select this component when a 120 µH inductance value is required for power filtering applications. Consider the 800 mA continuous current rating against circuit load requirements. Evaluate the 460 mΩ DC resistance for efficiency constraints. Ensure the 10.40mm x 10.40mm package fits within the designated PCB area. Verify thermal management needs given the operating temperature limits.
