Procurement Notes

Verify the specific suffix R2A3L against official Murata documentation to confirm exact packaging and terminal configuration. Ensure the selected variant matches the required 1206 footprint and 100V rating for your circuit design. Cross-reference the datasheet for precise impedance characteristics at target frequencies to validate performance suitability.

Selection Notes

Select this component when high current handling capability up to 10 A is required alongside low impedance filtering. The 1206 package size balances board space constraints with thermal performance. Confirm that the X7R dielectric stability meets the operational temperature requirements of the specific application environment.

Part Context

This part belongs to the NFM31KC series of feedthrough capacitors, which are engineered for high-frequency noise suppression. The series is characterized by its ability to handle significant current loads while maintaining low insertion loss. It serves as a critical component for maintaining signal integrity in noisy electrical environments.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 10 nF capacitance, 100V rating, and 10 A current capacity. Verify equivalent AEC-Q200 qualification if used in automotive contexts. Consult manufacturer cross-reference lists for verified alternatives with identical electrical specifications.
