GRM31CR61C475KA01K

The GRM31CR61C475KA01K is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across industrial, consumer, and automotive electronics applications. Multilayer ceramic capacitors like this model serve as fundamental building blocks in electronic circuits, functioning as energy storage elements, filtering components, and noise suppression devices. The GRM31 designation indicates this is a 1206-case-size capacitor, which is a standard SMD (surface-mount device) package measuring approximately 3.2mm by 1.6mm. This mid-range package size strikes a practical balance between component density and ease of handling during assembly, making it popular in both prototype development and high-volume manufacturing environments. The "CR" specification within the part number indicates this capacitor is designed with X7R dielectric material. X7R ceramics are temperature-stable formulations that maintain relatively consistent capacitance values across a wide operating temperature range, making them suitable for applications where temperature fluctuations are a concern. This characteristic makes X7R capacitors preferable to less stable ceramic types in industrial control systems, power supplies, telecommunications equipment, and automotive electronics where reliability across temperature variations is critical. Based on the part number's construction, this component is specified for general-purpose decoupling, filtering, and coupling applications in circuits operating at moderate voltage levels. Engineers commonly specify capacitors from this series in power supply designs, signal conditioning circuits, timing applications, and general board-level filtering where cost-effectiveness and space efficiency matter. The choice of an MLCC like the GRM31CR61C475KA01K over alternative technologies depends on several factors. Compared to film capacitors, MLCCs offer superior miniaturization and volumetric efficiency. Compared to electrolytic capacitors, they provide better high-frequency performance and longer operational life. Compared to specialty capacitors, they deliver excellent price-to-performance value for mainstream industrial applications. Murata's GRM series maintains reputation for consistency in manufacturing and reliable performance across commercial and industrial temperature ranges. This makes the GRM31CR61C475KA01K suitable for designers seeking proven, widely-adopted components with established supply chains and predictable long-term availability. This capacitor is appropriate for incorporation into industrial automation systems, measurement instrumentation, power conversion equipment, embedded control systems, and general-purpose electronic assemblies where reliable passive component performance is required.
