105R-472H

Overview

The Delevan 105R-472H is a fixed, unshielded power inductor designed for surface-mount applications. It features a nominal inductance of 4.7 µH with a tolerance of ±3%. The component utilizes an iron core material and exhibits a maximum DC resistance of 3.1 Ohms. It supports a maximum DC current rating of 175 mA. The unit operates within a temperature range of -55°C to +125°C and is housed in a non-standard package configuration.

Feature Summary

• Unshielded construction utilizing an iron core for general-purpose power filtering
• Surface-mount design compatible with standard PCB assembly processes
• Wide operational temperature range suitable for demanding environments

Applications

• General-purpose power supply filtering
• DC-DC converter input/output stages
• Signal conditioning circuits requiring low-current inductance

Procurement Notes

Verify the specific manufacturer suffix and RoHS compliance status against the latest official datasheet, as legacy variants may differ. Confirm that the non-standard package dimensions match your PCB footprint requirements precisely before finalizing procurement orders.

Selection Notes

Select this component when an unshielded, iron-core inductor is required for low-current applications. Ensure the 175 mA current rating meets the circuit's peak load demands. Verify that the 3.1 Ohm DC resistance does not cause excessive voltage drop in the target application path.

Part Context

This part belongs to the Delevan fixed inductor family, specifically the 105R series. These components are engineered for compact electronic designs where space efficiency is prioritized alongside reliable inductive performance for power management tasks.

Replacement Considerations

The 105R-472G is a documented variant within the same series offering identical electrical specifications but potentially differing in lead finish or packaging details.
