Procurement Notes

Verify the exact part number suffix against official documentation, as variations such as KS or H may indicate differences in tolerance or shielding status. Confirm availability through authorized distributors, noting that some listings may indicate discontinued status or limited stock. Ensure the component meets RoHS compliance requirements for your specific manufacturing process.

Selection Notes

Select this component when an unshielded RF inductor with 560 nH nominal value is required. Consider the 145 mOhms DC resistance and 820 mA current limit for power handling needs. The 1.22 GHz self-resonant frequency defines the upper operational limit. Compare against shielded alternatives if electromagnetic interference suppression is critical for the design.
