Procurement Notes

Verify the complete part number including suffixes against official TDK documentation to ensure correct capacitance, tolerance, and termination specifications. Confirm AEC-Q200 qualification status if automotive compliance is required. Check datasheet revisions for any updates to mechanical dimensions or recommended soldering profiles prior to integration into production designs.

Selection Notes

Select this component when space-constrained automotive designs require high-current handling capability alongside EMI filtering. The 0805 footprint offers a balance between parasitic inductance reduction and board area efficiency. Ensure the 1 A current rating aligns with the specific circuit requirements and that the 50 V rating exceeds the maximum operating voltage with appropriate margin.

Part Context

This component belongs to the TDK YFF series of three-terminal feedthrough capacitors. These devices are specifically engineered to provide superior high-frequency noise attenuation compared to standard two-terminal capacitors by minimizing lead inductance. The series is widely utilized in modern electronic systems where electromagnetic compatibility is critical.

Replacement Considerations

Consult official TDK substitution guides for compatible alternatives within the YFF family. Verify that any substitute matches the 0805 footprint, 22 pF capacitance, 50 V rating, and AEC-Q200 qualification to maintain system integrity and regulatory compliance.
