Procurement Notes

Verify the specific suffix GS against official manufacturer documentation to confirm the exact tolerance and electrical characteristics, as suffixes often denote variations within the series. Ensure compatibility with standard SMD reflow processes and check RoHS compliance status through the latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a 1.5 µH inductance value is required with tight 2% tolerance. Consider the 340 mA current rating and 840 mΩ DCR for power handling requirements. The unshielded nature requires layout consideration to minimize electromagnetic interference coupling with adjacent components.

Part Context

This part belongs to the Delevan 103/R series of fixed RF inductors. These components are designed for high-frequency applications where compact size and stable performance are critical. The series offers various inductance values and tolerances to suit different RF circuit designs.

Replacement Considerations

Cross-reference with other 103R series variants such as 103R-152FS or 103R-152JS if tolerance differences are acceptable. Verify pinout and dimensional compatibility before substituting with components from other manufacturers offering similar RF inductor specifications.
