Procurement Notes
Verify the complete part number including suffixes against official TDK documentation to ensure correct packaging and specifications. Confirm AEC-Q200 qualification status if required for your specific application. Check current availability through authorized distributors as lead times may vary.
Selection Notes
Select this component when a low-capacitance, high-reliability feed-through filter is needed for automotive or industrial applications. Ensure the 50V rating and 470pF value suit your circuit requirements. Consider the 0805 package size for space-constrained PCB layouts requiring robust EMI performance.
Part Context
This component belongs to the TDK YFF-AC series of feed-through capacitors. These components are specifically engineered for electromagnetic interference suppression in environments requiring high reliability and compact form factors. The series supports various capacitance values while maintaining consistent electrical characteristics across the family.
Replacement Considerations
Consult TDK's official substitution guide for compatible alternatives within the YFF-AC series. Verify that any substitute maintains the same capacitance, voltage rating, and AEC-Q200 qualification. Cross-reference pin configurations and thermal characteristics before implementation.
