GRM31A5C2J680JW01D

The GRM31A5C2J680JW01D 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 is widely used in consumer electronics, industrial equipment, telecommunications, and automotive applications. Multilayer ceramic capacitors are among the most commonly used capacitor types in modern electronics due to their small size, reliability, and cost-effectiveness. The GRM31 designation indicates this is a surface-mount component in a 1206 package size, a standard rectangular form factor that balances ease of assembly with reasonable capacitance density. This package type is compatible with automated pick-and-place manufacturing processes used in high-volume PCB assembly. The part number suffix "J680" indicates the capacitance value and tolerance class of this specific component. Capacitors from this series are available across a wide range of capacitance values and voltage ratings, making the GRM series suitable for diverse circuit design requirements. Engineers commonly specify Murata's GRM MLCCs in coupling and decoupling applications, where they filter high-frequency noise and stabilize power distribution across integrated circuits. They are also found in timing circuits, signal conditioning networks, and impedance matching applications. The GRM31 series is designed for general-purpose use in consumer and industrial products where reliability and performance consistency matter. Murata's manufacturing processes ensure consistent electrical characteristics across production batches, which is critical for applications requiring predictable circuit behavior. The ceramic dielectric material used in these capacitors provides stable capacitance across operating temperatures and applied voltages, though some derating may occur under certain conditions—a characteristic typical of ceramic capacitors. Engineers choose this specific part number when they need a compact, reliable capacitor with Murata's quality reputation and proven field performance. The 1206 package offers practical advantages: it's large enough to handle in manual rework if needed, yet small enough for high-density PCB layouts. For designers working with established design guidelines or those updating existing products, specifying a known Murata part minimizes qualification risk and supply chain complexity. This component is RoHS compliant, reflecting current environmental standards for electronics manufacturing. It is suitable for both military/aerospace applications and standard commercial-grade products, depending on the specific voltage and temperature ratings of the particular capacitor value selected from the GRM series.
