Procurement Notes
Verify the obsolete status of this specific part number before procurement planning. Confirm availability through authorized distributors or surplus suppliers, as original manufacturing may have ceased. Ensure that substitute components meet identical electrical specifications and mechanical footprint requirements to maintain circuit integrity.
Selection Notes
Select this component only if its 79 mA current rating and 4.2 Ohm DC resistance align with the target circuit's power constraints. The 15 µH value must match the required impedance characteristics for the intended frequency range. Verify that the small SMD package fits within the available board space constraints.
Part Context
This component belongs to the API Delevan fixed inductor family, specifically designed for surface mount applications. It serves as a passive electronic component used to block high-frequency AC signals while allowing DC or low-frequency signals to pass. The model designation indicates specific electrical parameters within the manufacturer's standardized product line.
Replacement Considerations
DigiKey lists this product as obsolete with available substitutes. Identify compatible fixed inductors from other manufacturers that offer 15 µH inductance, similar current ratings, and matching SMD footprints. Cross-reference datasheets to ensure equivalent self-resonant frequencies and DC resistance values.
