It features a maximum DC resistance of 220 mΩ and a rated current of 675 mA. The component measures 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. It utilizes standard terminations and is supplied in reel packaging.

Feature Summary

• Unshielded construction for minimal magnetic interference
• Surface-mount design for automated PCB assembly
• Standard termination configuration

Applications

• RF circuit filtering
• Impedance matching networks
• Signal processing circuits

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets are often managed by other entities. Confirm RoHS compliance status directly with the supplier, as documentation varies across distributors. Ensure the ordering suffix matches the required tolerance and packaging format to avoid receiving variants with different electrical characteristics or supply formats.

Selection Notes

Select this component for applications requiring precise 220 nH inductance with tight 2% tolerance. Consider the 675 mA current rating and 220 mΩ DC resistance for power handling requirements. The small 0805 footprint suits space-constrained designs. Verify self-resonant frequency limits against the target operating frequency to ensure effective performance.
