• Power line choke applications
• DC-DC converter circuits
• General-purpose power supply filtering

Procurement Notes

Verify the specific suffix "+P3" against official documentation to confirm packaging configuration. Note that this component is classified as Not Recommended for New Designs (NRND) with an End-of-Life date of March 5, 2026. Ensure procurement plans account for the final sales date of March 31, 2027, and potential availability constraints due to the obsolescence status.

Selection Notes

Select this component when a shielded 82 µH inductor with a 1 A rated current is required. The 10.40 mm square footprint suits space-constrained PCB layouts. Verify thermal requirements against the +85°C maximum operating limit. Consider the NRND status for long-term production viability and evaluate alternative components if future-proofing is a priority.
