Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and generic Delevan branding. Confirm RoHS compliance status through official documentation. Ensure the ordering suffix matches the required tolerance and packaging format. Cross-reference the part number against distributor databases to confirm availability and lead times prior to procurement.

Selection Notes

Select this component for designs requiring a 1.8 µH inductance with tight 2% tolerance. The unshielded structure may require consideration regarding electromagnetic interference coupling. Evaluate the 325 mA current rating against circuit load requirements. Verify that the 28 MHz self-resonant frequency aligns with the target operating band.

Part Context

This part belongs to the Delevan fixed inductor family, categorized under RF Inductors - SMD. It shares the 1.8 µH value with other series members like the 103R-182HS but differs in tolerance and physical dimensions. The 103R series typically utilizes a small rectangular form factor distinct from larger shielded variants.
