Fixed Inductors Procurement Notes

Verify the specific suffix J indicates a 5% tolerance when sourcing replacements. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability data for the ferrite core material. Cross-reference the DCR value against circuit requirements to prevent thermal issues. Validate that the shielding type matches the design's EMI constraints.

Fixed Inductors Selection Notes

Select this component for designs requiring precise 100 nH inductance with tight 5% tolerance. The shielded architecture is essential for noise-sensitive RF environments. Evaluate the 1.02 A current rating against peak load conditions. Consider the 383 MHz self-resonant frequency to ensure operation below the resonant limit. Compare the 90 mOhm DCR against efficiency targets in power paths.

Fixed Inductors Part Context

This part belongs to the S1008R series of fixed RF inductors manufactured by Delevan. The series offers various inductance values within the 1008 package size. The S1008R-101J specifically addresses low-inductance RF filtering needs. It complements other variants like the S1008R-101G and S1008R-101K which offer different tolerances or unshielded options.

Fixed Inductors Replacement Considerations

S1008R-101F serves as a higher precision alternative with 1% tolerance. S1008R-101K offers a wider 10% tolerance option. HF1008R-101G is an unshielded variant with similar inductance but lower current handling.
