105R-222K

Overview

The Delevan 105R-222K is a fixed power inductor designed for surface-mount technology (SMD) applications. It features an unshielded construction with a nominal inductance of 2.2 µH and a tolerance of ±10%. The component has a maximum DC resistance of 1.7 Ohms and supports a maximum DC current of 235 mA. It utilizes a nonstandard two-lead package configuration suitable for PCB mounting.

Feature Summary

• Unshielded SMD design for general-purpose power filtering
• Ferrite core construction for stable inductance characteristics
• Two-lead nonstandard package format for flexible board layout

Applications

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

Procurement Notes

Verify the specific package dimensions against the official datasheet, as the nonstandard lead configuration may differ from typical SMD footprints. Confirm RoHS compliance status through the manufacturer's latest documentation before integration into regulated assemblies.

Selection Notes

Select this component when unshielded performance is acceptable to minimize size and cost. Ensure the operating current remains below the 235 mA limit to prevent saturation. Consider thermal management due to the relatively high DC resistance compared to shielded alternatives.

Part Context

This part belongs to the Delevan fixed inductor portfolio, targeting applications where standard SMD footprints are insufficient. It serves as a specialized alternative to common chip inductors, offering higher current handling capabilities within a compact form factor for power electronics designs.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific nonstandard package variant. Evaluate generic 2.2 µH power inductors only if custom footprint adaptation is feasible.
