GRM31CR72A105KA01K

The GRM31CR72A105KA01K is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is designed for general-purpose applications in electronic circuits where stable capacitance and reliable performance are essential requirements. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics, used extensively in filtering, decoupling, coupling, and energy storage applications across consumer, industrial, and automotive sectors. The GRM31CR72A105KA01K belongs to Murata's GRM series, which represents a broad family of commercial-grade MLCCs engineered for cost-effective performance in standard operating conditions. The "31" designation in the part number indicates this capacitor uses a 1206 package size (3.2mm x 1.6mm), making it a standard surface-mount component suitable for automated assembly on printed circuit boards. This package size offers a practical balance between compact footprint and ease of handling, making it popular in space-constrained applications while remaining straightforward to solder. The "CR" designation identifies this as a capacitor in Murata's commercial reliability class, optimized for typical industrial and consumer applications rather than military or extreme-environment specifications. These capacitors deliver consistent performance under normal operating conditions without the premium cost associated with higher-grade classifications. Engineers specify components from this series when designing circuits that require dependable capacitance values without specialized performance requirements such as extreme temperature tolerance, high-voltage operation, or specialized environmental specifications. Common applications include power supply filtering in microcontroller circuits, noise suppression in digital signal paths, and general decoupling across power distribution networks. The Murata GRM series is known for manufacturing consistency and proven reliability in high-volume production, making it a trusted choice for OEM manufacturers and circuit designers who prioritize supply chain stability. These capacitors are compatible with standard reflow soldering processes and meet the requirements of automated PCB assembly operations. When selecting this specific part number over alternatives, engineers benefit from Murata's quality reputation, the established performance characteristics of the GRM series, and the component's suitability for standard commercial applications. This part represents a practical solution for mainstream electronic design where component reliability and manufacturing availability are important considerations alongside performance specifications.
