GRM31CR61E106KA12K

The GRM31CR61E106KA12K 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 filtering, decoupling, and signal coupling applications across a wide range of industrial and commercial electronic equipment. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronics, used extensively in power supplies, audio circuits, RF applications, and digital signal processing equipment. The "GRM31" series designation indicates this is a general-purpose MLCC in a compact surface-mount package, suitable for automated assembly in high-volume manufacturing environments. These capacitors are widely specified in consumer electronics, telecommunications equipment, industrial control systems, and automotive applications where reliable, cost-effective capacitance is required. The part number coding reveals several key characteristics of this component. The package type is a standard 1206-size surface-mount format (approximately 3.2mm x 1.6mm), making it compatible with standard PCB assembly equipment and design practices. This size offers a practical balance between component density and ease of handling during manufacturing. The "E" in the part number indicates the dielectric material classification, which relates to the capacitor's temperature stability and voltage characteristics. Murata's GRM31 series typically offers stable performance across industrial temperature ranges, making these capacitors suitable for applications requiring consistent operation in varying environmental conditions. Engineers select this specific Murata part for several practical reasons. Murata's reputation for quality and reliability means consistent performance across production batches, reducing field failures and warranty issues. The GRM31 series is widely used in established designs, meaning design engineers can reference proven application circuits and installation guidelines. The standardized 1206 package ensures easy sourcing of replacement components and compatibility with standard PCB layouts. Additionally, Murata's broad product range means this particular part number is likely optimized for a specific combination of capacitance value, voltage rating, and temperature characteristics that may be difficult to match exactly with alternative suppliers. For engineers involved in board-level design, manufacturing, or maintenance, this capacitor represents a reliable, industry-standard solution for decoupling power supplies, filtering noise, and coupling signals in countless applications. Its widespread adoption across industries makes it a sensible default choice when general-purpose capacitance is needed in a compact surface-mount package, while maintaining the quality standards expected in professional electronics manufacturing.
