GRM31CR71C475KA01K

The GRM31CR71C475KA01K is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor is part of Murata's GRM series, which is widely recognized in the electronics industry for reliable performance across consumer, industrial, and automotive applications. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronic circuits. They function to store and release electrical energy, filter noise, stabilize voltage supplies, and couple or bypass signals in countless applications. The GRM31 designation indicates this is a compact surface-mount device designed for automated assembly on printed circuit boards, making it ideal for space-constrained designs where miniaturization is critical. The part number suffix reveals important characteristics about this specific variant. The "CR" designation indicates this capacitor features X7R dielectric material, which provides stable capacitance performance across a wide temperature range. This makes it particularly suitable for industrial and automotive environments where components must maintain consistent performance despite temperature fluctuations. The X7R classification is preferred over general-purpose Y5V dielectrics when capacitance stability and reliability are paramount concerns. This component finds application in numerous industries and circuit functions. Automotive electronics frequently specify Murata's GRM series capacitors for engine control modules, body electronics, and infotainment systems. Industrial equipment manufacturers use these capacitors in power supplies, motor drives, and control circuits. Consumer electronics applications range from smartphones and tablets to IoT devices and portable instrumentation. The small package size combined with reliable performance makes these capacitors particularly valuable in compact modern electronics. Engineers typically specify the GRM31CR71C475KA01K when they need a compact, reliable capacitor with stable performance characteristics and proven long-term field reliability. The Murata GRM series has established itself through widespread adoption and consistent quality, reducing design risk compared to lesser-known alternatives. The X7R dielectric ensures that performance specifications remain within acceptable tolerances across the operating temperature range, which is critical for applications requiring predictable circuit behavior. The 0603 package size (1.6mm × 0.8mm) makes this capacitor suitable for high-density PCB layouts without requiring specialized assembly equipment beyond standard surface-mount processes. This combination of proven reliability, compact form factor, stable performance characteristics, and established supply chain availability makes this component a logical choice for engineers specifying capacitors for demanding applications where failure is not an option.
