106-222K

Overview

The Delevan 106-222K is a fixed surface-mount inductor with a nominal inductance of 2.2 µH and a tolerance of ±10%. It features an unshielded wirewound construction using an iron core, designed for RF applications. The component has a maximum DC resistance of 1.5 Ω and a rated current of 250 mA. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• Unshielded wirewound design utilizing an iron core for general-purpose RF applications
• Surface-mount package configuration suitable for automated PCB assembly
• Robust thermal performance supporting operation across extended industrial temperature ranges

Applications

• RF circuit filtering
• General-purpose signal processing
• Power supply input/output chokes

Procurement Notes

Verify compliance status as the 106 series may contain lead. Confirm RoHS and REACH alignment with specific project requirements before integration. Check datasheet revisions for potential marking or packaging changes. Ensure availability through authorized API Delevan distributors to guarantee authenticity and traceability.

Selection Notes

Select this component for designs requiring a 2.2 µH value with moderate current handling. The unshielded nature requires careful layout to minimize magnetic interference with nearby traces. Verify that the 1.5 Ω DCR meets voltage drop constraints and that the 250 mA rating exceeds peak load currents.

Part Context

This part belongs to the API Delevan 106 series of fixed inductors. These components are characterized by their wirewound construction and iron cores, distinguishing them from ferrite-core alternatives. The series provides standard values for general electronic filtering needs.

Replacement Considerations

Direct substitutes include the 106-222J variant, which offers tighter tolerance. Cross-brand replacements require matching the 2.2 µH inductance, 250 mA current rating, and 1.5 Ω DCR specifications.
