Procurement Notes

Verify the complete part number including the suffix EGTS to ensure correct packaging and specifications. Confirm RoHS3 compliance status as required by project regulations. Check manufacturer datasheets for specific handling instructions regarding moisture sensitivity level 1. Ensure compatibility with automated pick-and-place equipment given the 0805 package footprint.

Selection Notes

Select this component when a compact 47 nH inductance is required for high-current applications up to 600 mA. The unshielded design may influence nearby circuit layout due to magnetic field exposure. Consider the 390 mΩ DCR impact on power loss calculations. Verify that the 0805 footprint aligns with the PCB design constraints and that the operating temperature range meets environmental requirements.

Part Context

This component belongs to the 0805CT series of fixed power inductors manufactured by Delta Electronics/Components. The series utilizes wirewound technology with ceramic cores to provide stable inductance values in small surface-mount packages. Delta supplies passive and magnetic components for various sectors including IoT, automotive, and consumer electronics.

Replacement Considerations

The 0805CS-470EGTS is a related variant within the same package family but differs in electrical ratings, specifically offering 500 mA current capacity and 310 mΩ DCR. Direct substitution requires verification of current handling and impedance characteristics against the original design requirements.
