Procurement Notes

Verify the specific suffix =P3 against official Murata documentation to confirm packaging configuration, as suffixes may denote reel or cut tape variations. Confirm RoHS compliance status and lead-free characteristics prior to integration. Check for End-of-Life notifications or Last Time Buy dates, as availability may be restricted. Ensure the supplier provides valid traceability documents matching the manufacturer's part number exactly.

Selection Notes

Select this component when a compact 82 µH inductor with 1 A current rating is required for space-constrained designs. The shielded structure makes it suitable for noise-sensitive environments. Compare DCR and saturation current requirements against circuit load conditions. Verify that the operating temperature range up to +85°C meets the system's thermal profile. Consider the non-standard footprint dimensions for PCB layout constraints.
