Fixed Inductors Procurement Notes

Verify the manufacturer part number against official API Delevan documentation to confirm specifications. Ensure compatibility with RoHS requirements if applicable to your region. Check for any specific handling instructions regarding surface-mount thermal profiles during soldering. Confirm availability through authorized distributors as stock levels may vary.

Fixed Inductors Selection Notes

Select this component when a 560 µH inductance value is required within a compact 12x12 mm footprint. Consider the 550 mA current rating to ensure operation remains within safe limits without saturation. The shielded design is suitable for dense layouts where magnetic coupling must be controlled. Verify that the 1 ohm DC resistance aligns with efficiency targets for the target power stage.

Fixed Inductors Part Context

This part belongs to the SPD125R series of shielded power inductors from API Delevan. The series is characterized by its robust ferrite core construction and standardized SMD package dimensions.
