GRM2165C2A911JA01D

The GRM2165C2A911JA01D 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 represents a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, telecommunications, and automotive applications. Multilayer ceramic capacitors are among the most commonly specified passive components in modern electronics. They function to store and release electrical energy, smooth power supply ripple, filter high-frequency noise, couple or decouple signals, and stabilize voltage rails in circuits. The GRM series is engineered for reliable performance in standard industrial and consumer applications where cost-effectiveness and proven reliability are priorities. The part number structure indicates specific electrical characteristics. The "2165" designator identifies the physical package size and form factor—a surface-mount rectangular package suitable for automated assembly on printed circuit boards. This package type is compact and stackable, making it ideal for space-constrained designs where board real estate is valuable. The "C2A" portion references the capacitor's dielectric material class and voltage rating, typically corresponding to general-purpose ceramic formulations designed for moderate voltage applications found in most consumer and industrial electronics. Engineers specify Murata GRM series capacitors for several reasons. First, Murata maintains strict quality control and manufacturing consistency, resulting in tight tolerance specifications and reliable performance across operating temperature ranges. Second, these capacitors are widely available through multiple distribution channels, reducing supply chain risk for high-volume production. Third, the GRM series offers excellent value, providing reliable performance at competitive price points compared to premium alternatives. Fourth, extensive design documentation and application notes are readily available, supporting rapid circuit design and qualification. This particular part number is typically selected for applications requiring a standard ceramic capacitor in a specific package size and electrical configuration. Common use cases include decoupling and bypass applications on power distribution networks, noise filtering on analog and digital signal lines, timing circuits, and general-purpose energy storage. The component would be found in industrial control systems, power supplies, audio equipment, data acquisition systems, and numerous consumer electronics devices. For engineers evaluating this part, consideration should be given to application-specific requirements including voltage stress, temperature cycling, frequency response needs, and mechanical shock resistance. Murata's GRM series is designed to perform reliably in these varied environments, making it a trusted choice for production designs that require established component quality without premium specifications.
