105R-472F

Overview

The Delevan 105R-472F is a fixed surface-mount power inductor with an inductance of 4.7 µH and a tolerance of ±1%. It features a maximum DC current rating of 175 mA and a maximum DC resistance of 3.1 Ohms. The component utilizes a shielded design to minimize electromagnetic interference, constructed with a ferrite core and wirewound technology. It is housed in a compact SMD package suitable for automated PCB assembly processes.

Feature Summary

Shielded construction reduces magnetic flux leakage
Ferrite core material ensures stable inductance characteristics
Wirewound winding technique supports precise electrical performance

Applications

Power supply filtering circuits
DC-DC converter input/output stages
Signal conditioning networks

Procurement Notes

Verify component availability status as the part may be discontinued or obsolete. Confirm RoHS compliance details through official manufacturer documentation prior to integration. Validate that the specific suffix matches the required tolerance and current ratings for the target application circuit design requirements.

Selection Notes

Select this component when low current handling capability is sufficient for the power stage. The shielded architecture is appropriate for noise-sensitive environments. Ensure the physical footprint dimensions align with the PCB layout constraints and thermal management requirements of the final assembly design.

Part Context

This part belongs to the Delevan fixed inductor family designed for general-purpose electronic applications. It serves as a passive energy storage element within power conversion topologies. The series provides standardized form factors for reliable manufacturing integration across various consumer and industrial electronic device platforms.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalent parts. Cross-reference inductance values, current ratings, and physical dimensions to ensure functional compatibility without redesigning the printed circuit board layout.
