Fixed Inductors Procurement Notes

Verify RoHS compliance status directly with the manufacturer, as documentation indicates non-compliance for this specific part number. Confirm availability through authorized distributors, as inventory levels fluctuate. Ensure the ordering suffix matches the required tolerance specification. Request official datasheets and material certificates prior to finalizing procurement orders to validate technical parameters against design requirements.

Fixed Inductors Selection Notes

Select this component when a shielded inductor with 33 µH nominal value is required for RF designs. Consider the 125 mA current limit and 7.4 Ohm DC resistance for power budget calculations. Compare against unshielded variants if magnetic coupling is not a constraint. Verify that the 12 MHz self-resonant frequency aligns with the target operating band. Check alternative tolerances such as K or F suffixes if tighter specifications are needed.

Fixed Inductors Part Context

This part belongs to the S1008/R series of fixed inductors manufactured by Delevan. The series provides various inductance values in the standardized 1008 (2520 metric) surface-mount package. Shielded versions utilize ferrite cores to contain magnetic fields, distinguishing them from unshielded counterparts in the same footprint family.

Fixed Inductors Replacement Considerations

S1008R-333K is documented as a direct substitute with identical electrical characteristics but potentially different tolerance specifications.
