Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official TE Connectivity datasheet prior to integration. Confirm that the 0603 package dimensions align with your PCB land pattern requirements. Ensure the selected variant meets the required AEC-Q200 qualification if used in automotive environments. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when space-constrained designs require effective EMI suppression in power lines carrying up to 1 A. The 9 Ohm impedance at 100 MHz targets common high-frequency noise profiles. Consider the low DCR of 80 mOhms to maintain efficiency in power delivery networks. Verify thermal performance within the -40°C to +125°C operating range for your specific application environment.
