Procurement Notes

Verify the manufacturer designation as API Delevan Inc. or Delevan when sourcing this component. Confirm that the part number matches the specific 180 nH value and 5% tolerance requirements. Ensure the unshielded characteristic aligns with the electromagnetic interference constraints of the target application. Check for any RoHS compliance documentation if required by the project specifications.

Selection Notes

Select this inductor for applications requiring a compact 103/R series footprint with specific RF performance characteristics. Consider the 695 mA current rating and 200 mOhm resistance for power handling needs. The unshielded design may influence layout decisions regarding magnetic coupling. Verify that the 180 nH inductance meets the frequency response requirements of the intended circuit topology.

Part Context

This component belongs to the Delevan 103/R series of RF inductors. It is categorized under Surface Mount Device (SMD) types within the broader Inductors, Chokes & Coils product family. The 103R-181JS shares dimensional similarities with other parts in the 103R series, such as the 103R-121KS and 103R-681HS, differing primarily in inductance values and associated electrical parameters.
