Procurement Notes

Verify the complete part number including suffixes against official TDK documentation to ensure correct capacitance and packaging specifications. Confirm that the intended application environment aligns with the AEC-Q200 automotive grade requirements and the specified operating temperature range before finalizing procurement decisions.

Selection Notes

Select this component when a 220 pF feedthrough filter is required for 50 V automotive circuits. Ensure the design accommodates the 0603 footprint and four-pad configuration. Validate that the 1 A current rating and insertion loss characteristics meet the specific signal integrity needs of the target application.

Part Context

This component belongs to the TDK YFF-AC series, which consists of ceramic feedthrough capacitors specifically developed for automotive use. The series offers various capacitance values within the same 0603 form factor, allowing designers to standardize footprints across different filtering requirements while maintaining consistent mechanical and thermal performance profiles.

Replacement Considerations

Consult official TDK substitution guides for verified equivalents. Cross-referencing requires matching capacitance, voltage rating, package dimensions, and AEC-Q200 qualification status to ensure functional compatibility without redesigning the PCB layout.
