NFM31KC104R2A3L

Overview

The NFM31KC104R2A3L is a three-terminal feed-through capacitor from Murata Electronics, designed for high-frequency noise suppression. It features a capacitance of 0.1 µF with a tolerance of ±20% and a DC voltage rating of 100 VDC. The component operates within a temperature range of -55°C to +105°C and has a low impedance of 3 mΩ. Rated for 6 A current, it utilizes an SMD/SMT termination type in a 1206 (3216 Metric) package measuring 3.2 mm by 1.6 mm.

Feature Summary

• Three-terminal feed-through architecture provides effective electromagnetic interference filtering
• Low internal resistance supports high-current power line applications
• Multilayer ceramic construction ensures stability across wide temperature ranges

Applications

• Power supply input filtering
• High-speed digital circuit noise suppression
• Automotive electronics EMI reduction

Procurement Notes

Verify the specific suffix R2A3L against official Murata documentation to confirm exact tolerance and termination specifications. Ensure the procurement channel sources genuine components to guarantee compliance with AEC-Q200 automotive qualification standards if required for the target application environment.

Selection Notes

Select this component when a 0.1 µF capacitance value is required for power rail decoupling or filtering. The 100 VDC rating and 6 A current handling capability make it suitable for higher voltage systems compared to lower-rated alternatives. The 1206 footprint allows for compact PCB layouts while maintaining robust thermal performance.

Part Context

This part belongs to the NFM31 series of feed-through capacitors, which are engineered for superior high-frequency attenuation compared to standard MLCCs. The series is widely utilized in automotive and industrial sectors where reliable EMI suppression on power lines is critical for system integrity and regulatory compliance.

Replacement Considerations

Direct substitutes include other Murata NFM31 series parts with identical 1206 footprints and similar electrical ratings. Cross-brand replacements require matching the 0.1 µF capacitance, 100 VDC rating, and three-terminal configuration to ensure equivalent filtering performance.
