Procurement Notes

Verify the specific manufacturer designation, as API Delevan components may be listed under API Delevan Inc. Confirm RoHS compliance status through official documentation, as some sources indicate non-compliance. Ensure the unshielded variant matches the required electromagnetic interference specifications for the target application before procurement.

Selection Notes

Select this component for applications requiring high inductance in a small footprint. The low current rating necessitates careful thermal management. Verify that the 13 Ohm DC resistance aligns with system power loss constraints. Consider the unshielded nature when placing components near sensitive signal paths to prevent interference.

Part Context

This part belongs to the 108 series of fixed inductors from Delevan. It is designed for surface-mount technology (SMT) assembly. The component serves as a passive element in electronic circuits, providing impedance control and energy storage capabilities within specified electrical limits defined by its ferrite core and winding structure.

Replacement Considerations

The S108-333H is documented as a direct substitute. Verify compatibility regarding shielding type and exact electrical parameters before implementation.
