Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets may be managed by Eaton Electronics. Confirm RoHS compliance status through official documentation prior to procurement. Ensure the supplier provides valid traceability data for the component batch. Cross-reference the part number against current distributor catalogs to confirm availability and authenticity before finalizing purchase orders.

Selection Notes

Select this component for applications requiring precise 22 uH inductance with tight 3% tolerance in RF environments. The high DC resistance and low current rating suit low-power signal paths rather than power delivery. Consider the unshielded nature when designing layouts to minimize electromagnetic interference coupling with adjacent sensitive traces.
