It features a maximum DC resistance of 1 ohm and a minimum Q factor of 65 at its self-resonant frequency of 80 MHz. The component supports a maximum DC current of 310 mA and measures 4.14 mm in length, 3.38 mm in width, and 3.56 mm in height.

Feature Summary

• Unshielded chip construction for standard RF applications
• High precision 1% inductance tolerance
• Standard SMD/SMT termination style

Applications

• RF circuit design
• PCB mount implementations

Procurement Notes

Verify the specific manufacturer datasheet to confirm RoHS compliance status and exact electrical tolerances prior to procurement. Ensure the ordering suffix matches the required packaging configuration. Cross-reference the maximum DC current rating against the target application's operational requirements to prevent performance degradation or thermal issues during integration.

Selection Notes

Select this component when a precise 2.2 uH inductance value is required with tight 1% tolerance constraints. The unshielded design is suitable for layouts where magnetic interference is manageable. Consider the 80 MHz self-resonant frequency limit to ensure operation remains within the intended RF band without parasitic resonance effects impacting circuit stability.
