Procurement Notes

Verify the complete part number including suffixes such as CTAH0 to ensure correct packaging and compliance specifications. Confirm RoHS3 status and moisture sensitivity level requirements against project standards. Cross-reference datasheet parameters like impedance tolerance and DC current ratings with circuit design constraints before ordering.

Selection Notes

Select this component when a 470 Ohm impedance at 100 MHz is required for signal line filtering. Ensure the PCB layout accommodates the 0603 package dimensions. Verify that the circuit current does not exceed the 500 mA rating to prevent thermal issues. Consider the 300 mOhm DC resistance impact on voltage drop in low-voltage signal paths.
