Fixed Inductors Procurement Notes

Verify the specific suffix (JM vs KM) as it may indicate different tolerance levels or material compositions. Confirm RoHS compliance status directly with the manufacturer, as some listings indicate non-compliance. Ensure the ordering quantity matches the reel packaging requirements specified by the supplier.

Fixed Inductors Selection Notes

Select this component when a 68 µH inductance value is required within the RF spectrum. Consider the 180 mA current rating to ensure adequate headroom for the application. The axial package requires sufficient board space for leads. Compare against other ER1641 variants if different tolerance or current ratings are needed.

Fixed Inductors Part Context

This part belongs to the Delevan ER1641 series of fixed RF inductors. The series offers various inductance values ranging from nanohenries to microhenries. All parts share similar physical dimensions and shielding characteristics, differing primarily in electrical parameters like inductance, tolerance, and current handling capabilities.

Fixed Inductors Replacement Considerations

Direct substitutes include ER1641-683JM, which shares identical electrical specifications but may differ in tolerance designation. Verify pin compatibility and thermal characteristics before substitution.
