Fixed Inductors Procurement Notes

Verify the specific suffix '3' against the manufacturer's official datasheet to confirm the exact inductance value and tolerance, as suffixes often denote critical electrical variations. Ensure the through-hole mounting style aligns with your PCB design requirements. Confirm the operating temperature range meets your environmental specifications before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when a 220 µH unshielded inductor with a 5.5 A current rating is required for through-hole assembly. Consider the 80 mΩ DCR impact on power loss in your circuit design. Verify that the radial vertical form factor fits within your mechanical constraints and that the 10 kHz test frequency matches your application needs.
