GRM188C80E106ME47D

The GRM188C80E106ME47D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of electronic components. This capacitor belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors designed for widespread use in consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors are among the most commonly used passive components in modern electronics. They function as energy storage devices, signal coupling and decoupling elements, and noise filtering components in circuits. The GRM188 designation indicates this is a relatively compact surface-mount device, making it suitable for high-density PCB layouts where space is a critical constraint. The small footprint allows engineers to achieve miniaturization without sacrificing performance or reliability. The "C" in the part number indicates this capacitor uses a ceramic dielectric material, specifically a Class II formulation. Class II capacitors offer higher volumetric efficiency compared to Class I alternatives, allowing more capacitance to be packed into a smaller package. This makes them cost-effective for applications where moderate tolerance and temperature stability are acceptable. The trade-off is slightly more capacitance variation across temperature and voltage operating ranges compared to Class I types, but for most industrial and consumer applications, this performance is more than adequate. Murata's GRM series capacitors are specified into applications ranging from power supplies and audio equipment to automotive electronics, medical devices, and industrial control systems. They serve critical functions such as decoupling power supply noise, filtering high-frequency interference, and coupling AC signals while blocking DC components. Engineers select these capacitors for their proven reliability, consistent manufacturing quality, and wide availability across global supply chains. An engineer might choose the GRM188C80E106ME47D specifically when the application requires a capacitor with the exact capacitance value and voltage rating encoded in this part number, combined with Murata's quality assurance and the availability advantages of a standardized catalog part. Rather than using custom or harder-to-source components, specifying established GRM series parts reduces design risk, simplifies procurement, and often provides cost advantages through high-volume manufacturing. The GRM series has maintained consistent performance characteristics across decades of production, making it a reliable choice for both new designs and replacement applications in existing equipment. For engineers designing or maintaining industrial equipment, selecting this established Murata part ensures compatibility with well-documented circuit design guidelines and proven application notes.
