Procurement Notes

Verify the complete part number including suffixes to ensure correct capacitance, tolerance, and termination specifications. Confirm AEC-Q200 compliance if automotive application is required. Check datasheet for insertion loss characteristics at target frequencies. Ensure PCB footprint matches 0603 dimensions with four-pad configuration. Validate operating temperature range against system requirements.

Selection Notes

Select this component when low capacitance values are needed for high-frequency noise attenuation in space-constrained designs. The 0603 package allows for dense board layouts while maintaining robust current handling. Consider the specific insertion loss performance curve for the intended frequency band. Verify compatibility with reflow soldering profiles specified in the datasheet.
