Procurement Notes

Verify the exact suffix 'KS' against official manufacturer documentation to confirm packaging specifications and tolerance ratings. Ensure compatibility with standard SMD reflow processes. Cross-reference the part number with authorized distributors to validate authenticity and current production status before procurement.

Selection Notes

Select this component when an unshielded RF inductor with 15 uH inductance is required. Consider the 130 mA current limit and 5.6 Ohm DC resistance for power handling. Verify that the 28 MHz self-resonant frequency aligns with the target operating range. Compare with shielded alternatives if electromagnetic interference mitigation is necessary.

Part Context

This part belongs to the Delevan 103/R series of RF inductors. The series offers various inductance values and tolerances in a compact 0805-like footprint. These components are engineered for radio frequency applications requiring stable inductance characteristics.

Replacement Considerations

Check for direct substitutes within the same series, such as 103R-153JS or 103R-153K, noting differences in tolerance and packaging. Evaluate other manufacturers' 15 uH unshielded RF inductors with similar dimensional constraints and electrical parameters.
