106-122H

Overview

The Delevan 106-122H is a fixed surface-mount inductor designed for radio frequency applications. It features an unshielded wirewound construction with an iron core, housed in a nonstandard two-terminal package measuring approximately 4.57 mm in length and 1.91 mm in height. The component provides a nominal inductance of 1.2 µH with a tolerance of ±3%. It supports a maximum DC current of 335 mA and exhibits a maximum DC resistance of 900 mOhms. The device operates reliably within a temperature range of -55 °C to +125 °C.

Feature Summary

• Unshielded wirewound design suitable for general-purpose RF circuits
• Iron core construction for stable inductance performance
• Compact surface-mount form factor for PCB integration

Applications

• RF signal filtering
• General purpose inductive circuits
• Radio frequency choke applications

Procurement Notes

Verify the specific suffix designation when sourcing replacements, as variants such as 106-122G or 106-122F may exist with differing tolerances or compliance statuses. Confirm that the unshielded configuration aligns with your electromagnetic interference requirements. Ensure the operating temperature range meets your system's thermal specifications before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a 1.2 µH inductance value in a compact SMT footprint. The unshielded nature makes it appropriate where magnetic field isolation is not critical. Consider the 335 mA current rating to ensure adequate headroom for your circuit's peak loads. Verify compatibility with standard reflow soldering profiles given the iron core material.

Part Context

This part belongs to the API Delevan 106 series of fixed inductors. The manufacturer specializes in passive components for high-frequency and RF environments. The 106 series typically offers various inductance values in similar small outline packages, providing designers with standardized options for impedance matching and filtering tasks in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include the 106-122F and 106-122G from the same manufacturer family. These parts share identical physical dimensions and core materials but may differ in tolerance specifications or regulatory compliance status. Cross-reference datasheets to confirm electrical parameter equivalence before substitution.
