• AEC-Q200 qualified for reliable operation in automotive electronic environments
• High current handling capability suitable for power line filtering applications

Applications

• Automotive infotainment system power supply filtering
• Engine control unit (ECU) noise suppression
• Industrial control board EMI mitigation

Procurement Notes

Verify the specific suffix R1H3D against official Murata documentation to confirm packaging and tape specifications. Ensure the procurement channel sources genuine components from authorized distributors to maintain AEC-Q200 certification validity. Cross-reference the full part number with the manufacturer's latest datasheet to confirm current production status and compliance with RoHS3 directives before finalizing orders.

Selection Notes

Select this component when space-constrained designs require effective high-frequency noise reduction in automotive or industrial settings. The 0805 footprint allows for compact PCB layouts while maintaining robust current handling. Consider the 1000 pF capacitance value for balancing filtering performance with circuit impedance requirements. Verify thermal management capabilities align with the -55°C to +125°C operating range of the target application environment.

Part Context

This component is part of Murata's EMIFIL NFM21HC series, which specializes in three-terminal feedthrough capacitors for EMI suppression. The series offers various capacitance values within the same 0805 package form factor. These devices are engineered to replace traditional two-terminal capacitors by providing a direct ground path for high-frequency interference, thereby improving signal integrity in sensitive electronic circuits.

Replacement Considerations

Consult official Murata substitution guides for compatible alternatives within the NFM21HC or NFM21CC series. Verify that any substitute maintains identical package dimensions, terminal configuration, and electrical ratings to ensure mechanical and functional compatibility without redesigning the printed circuit board layout.
