Procurement Notes
Verify the complete part number including suffixes to ensure correct packaging and specifications. Confirm that the X7S dielectric and AEC-Q200 qualification align with specific project requirements. Check manufacturer documentation for RoHS compliance and SVHC status before integration into designs.
Selection Notes
Select this component when high current capacity and compact surface-mount form factor are required. The 1206 footprint allows for automated assembly. Ensure the 100V rating exceeds the maximum operating voltage. Consider the thermal performance and mounting orientation relative to the PCB layout for optimal signal integrity.
Part Context
This component belongs to the TDK YFF series of feedthrough capacitors. These devices integrate capacitor elements within a single package to minimize parasitic inductance. The series is engineered for high-frequency noise attenuation in space-constrained applications, particularly within the automotive sector where robustness and size efficiency are critical design parameters.
Replacement Considerations
Consult official substitution lists for compatible alternatives. Verify that any substitute matches the 1206 footprint, 0.1 µF capacitance, 100V rating, and 10A current handling. Ensure equivalent AEC-Q200 certification if automotive usage is intended.
