Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as the part contains lead. Validate electrical parameters against original datasheets before integration into production designs.

Selection Notes

Select this component for high-frequency applications requiring precise 18 µH inductance. Consider the low current rating of 75 mA when designing power paths. Ensure PCB layout accommodates the specific 2.54 x 2.54 mm footprint dimensions.

Part Context

This part belongs to the Delevan fixed inductor family designed for radio frequency environments. It serves as a specialized passive component for signal integrity management in electronic systems requiring stable inductive characteristics at high frequencies.

Replacement Considerations

Public confirmed substitute part numbers are not available in verified documentation. Due to the discontinued status, alternative sourcing requires careful validation of equivalent electrical and mechanical specifications.
