Fixed Inductors Procurement Notes

Verify the specific suffix 'J' indicates the 5% tolerance variant, as other suffixes may denote different tolerances or reliability grades. Confirm RoHS status and lead content requirements against project specifications, as older Delevan series may have varying compliance levels. Check for established reliability designations if used in high-reliability environments. Ensure the axial lead length meets board spacing requirements.

Fixed Inductors Selection Notes

Select this component when a 120 µH inductance with tight 5% tolerance is required for RF applications. Consider the low self-resonant frequency of 12 MHz to ensure operation below the resonant point. Evaluate the 66 mA current rating against peak load currents. Compare physical size constraints with available PCB real estate. Verify compatibility with standard through-hole assembly processes.
