• Unshielded design suitable for general power applications
• Surface-mount package optimized for compact PCB layouts

Applications

• Power supply filtering
• DC-DC converter circuits
• General-purpose signal blocking

Procurement Notes

Verify the manufacturer designation API Delevan against official documentation. Confirm RoHS compliance status through the specific datasheet. Ensure the 13 Ohm DC resistance and 45 mA current ratings match circuit requirements before procurement.

Selection Notes

Select this component for low-current applications requiring 33 uH inductance. The high DC resistance limits usage to low-power signals. Verify thermal management capabilities given the 45 mA saturation limit. Compare physical footprint constraints against available board space.

Part Context

This part belongs to the Delevan fixed inductor family. It utilizes a standard SMD form factor. The series provides reliable performance for basic power electronics. Ferrite cores are used for magnetic properties.

Replacement Considerations

Check for direct substitutes with identical 33 uH values and compatible current ratings. Verify pin compatibility and mechanical dimensions. Ensure equivalent thermal characteristics.
