GRM31M5C1H563JA01L

The GRM31M5C1H563JA01L 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 applications requiring reliable energy storage, filtering, and signal coupling in compact form factors across industrial, automotive, telecommunications, and consumer electronics markets. Multilayer ceramic capacitors like this model represent the most widely used capacitor technology in modern electronics due to their small footprint, cost-effectiveness, and excellent electrical performance. The GRM31 series designation indicates this is part of Murata's established general-purpose MLCC family, engineered for mainstream industrial and commercial applications rather than specialized military or aerospace requirements. The component uses the 1206 package format (metric designation 3216), which measures approximately 3.2mm by 1.6mm. This package size offers an optimal balance between component density and handling ease, making it suitable for high-volume automated assembly on modern PCBs. The 1206 package is among the most common and recognizable MLCC packages in electronics manufacturing, ensuring broad compatibility with standard pick-and-place equipment and reflow soldering processes. The "C" in the part number indicates X7R dielectric material, which provides relatively stable capacitance performance across temperature variations. This makes X7R capacitors a standard choice for general filtering, decoupling, and timing applications where moderate temperature stability is required but the extreme precision of C0G/NP0 dielectrics is unnecessary. The X7R classification means the capacitor maintains capacitance reasonably well over typical industrial temperature ranges, reducing the need for derating in many circuit designs. The "563" in the part number denotes a capacitance value in the tens of microfarads range, typical for filtering and energy storage in power distribution networks, audio circuits, and signal conditioning applications. Engineers frequently specify capacitors from this series in voltage regulator modules, power supplies, analog signal processing chains, and general PCB decoupling networks. Murata's GRM31 series is widely chosen in production designs because it combines predictable performance with established supply chain reliability. Design teams select this specific part number when X7R temperature stability, 1206 package compatibility, and the particular capacitance value meet their circuit requirements without requiring premium materials or tighter tolerances. The component's long production history and widespread adoption mean extensive design references and application notes are available throughout the electronics industry.
