Fixed Inductors Procurement Notes

Verify the specific suffix JP against official manufacturer documentation to confirm tolerance and electrical characteristics. Confirm RoHS status as non-compliant based on available distributor data. Ensure the ordering quantity aligns with reel packaging requirements specified by the supplier.

Fixed Inductors Selection Notes

Select this component when a 620 nH inductance with tight 5% tolerance is required for RF environments. Consider the 1.3 A current rating and low DCR for power handling needs. Verify that the axial package and physical dimensions fit the target PCB layout constraints.

Fixed Inductors Part Context

This part belongs to the Delevan ER1840 series of established reliability RF inductors. The series offers various inductance values and tolerances, all sharing similar physical dimensions and axial lead configurations. These components are typically used in military or high-reliability commercial electronics requiring stable RF performance.

Fixed Inductors Replacement Considerations

Check for direct substitutes within the ER1840 series such as ER1840-108JM or ER1840-108JR if tolerance variations are acceptable. Verify pin compatibility and inductance values before substitution.
