Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance or lead-containing variants. Confirm package type matches design requirements, as reel packaging is standard. Ensure supplier provides official datasheets to validate electrical parameters before integration into production schedules.

Selection Notes

Select this component for applications requiring precise 5.6 µH inductance with tight tolerance. Consider the unshielded nature when designing layouts to minimize electromagnetic interference coupling. Verify thermal limits and current ratings against circuit load conditions to ensure reliable operation within the specified temperature range.

Part Context
