Procurement Notes

Verify RoHS compliance status prior to procurement as documentation indicates non-compliance. Confirm lead availability and axial spacing requirements against target PCB layout specifications. Ensure operating temperature limits align with system thermal constraints. Validate supplier authenticity due to potential discontinuation or legacy status within the product lifecycle.

Selection Notes

Select this component when specific 6.8 µH inductance with low tolerance is required for axial mounting. Consider the 3.2 Ω DC resistance impact on circuit efficiency. Evaluate the 122 mA current limit against peak load conditions. Compare physical dimensions against available board space constraints for axial components.
