Procurement Notes

Verify the specific suffix codes against official TDK documentation to confirm dielectric type and tolerance specifications. Ensure the ordering part number matches the required capacitance value and voltage rating for the target application. Confirm packaging options such as cut tape or reel availability directly with authorized distributors to align with assembly requirements.

Selection Notes

Select this component when designing circuits requiring combined power handling and EMI filtering in small footprints. The 0805 form factor suits space-constrained automotive boards. Verify that the 400 mA current rating exceeds the maximum expected load current. Check impedance characteristics at target frequencies to ensure adequate attenuation performance for specific noise profiles.

Part Context

This component belongs to the TDK YFF-AC series, which specializes in automotive-grade feedthrough capacitors. These devices integrate capacitor elements with internal grounding structures to minimize parasitic inductance. The series is engineered specifically for harsh automotive environments, offering robust thermal stability and long-term reliability under vibration and temperature cycling conditions.

Replacement Considerations

Consult TDK's official cross-reference guides for direct substitutes within the YFF series. Verify that alternative parts match the 0805 footprint, 50V rating, and 2200pF capacitance. Ensure any replacement also holds AEC-Q200 certification if automotive compliance is mandatory.
