105R-222H

Overview

The Delevan 105R-222H is a surface-mount RF inductor with an inductance of 2.2 µH and a tolerance of ±3%. It features a maximum DC resistance of 1.7 Ω and a rated current of 235 mA. The component utilizes a shielded SMT construction to minimize electromagnetic interference. Designed for PCB mounting, it serves as a fixed inductor within the RF category, suitable for applications requiring stable impedance characteristics in compact electronic circuits.

Feature Summary

• Shielded surface-mount construction for reduced electromagnetic interference
• High precision inductance tolerance of ±3% for accurate circuit tuning
• Designed for direct PCB mounting in compact RF layouts

Applications

• RF signal processing circuits
• Impedance matching networks
• Filtering components in communication devices

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets are often managed under different corporate entities. Confirm RoHS compliance status and lead times directly with authorized suppliers or distributors. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, to align with assembly requirements.

Selection Notes

Select this component when a shielded RF inductor with tight tolerance is required. The 2.2 µH value suits mid-frequency filtering. Consider the 1.7 Ω DC resistance for power loss calculations. Compare against unshielded alternatives if magnetic coupling is not a concern, noting that shielded types generally offer better noise immunity in dense layouts.

Part Context

This part belongs to the broader category of fixed surface-mount inductors manufactured by Delevan (API). It is specifically categorized as an RF inductor, distinguishing it from power chokes or general-purpose components. The series typically targets high-frequency applications where size and shielding are critical design constraints.

Replacement Considerations

Direct substitutes include other shielded 2.2 µH SMD inductors with similar current ratings. Verify footprint compatibility and thermal performance. Unshielded variants like the 4232R-222H may require layout adjustments due to magnetic field exposure.
