Procurement Notes

Verify RoHS compliance status prior to procurement, as datasheets indicate lead-free variants (suffix F) exist alongside non-compliant versions. Confirm the specific tolerance code matches project requirements. Ensure the ordering suffix aligns with the desired lead finish and environmental certification to avoid integration issues during manufacturing.

Selection Notes

Select this component when a low-value inductance near 11 nH is required for high-frequency signal paths. Consider the 0.6 A current rating against peak circuit loads. Compare the 4000 MHz self-resonant frequency against target operating frequencies to ensure adequate performance margins above the fundamental signal band.
