GRM219R61E106MA12J

The GRM219R61E106MA12J is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor is designed for general-purpose applications across consumer electronics, industrial equipment, telecommunications, and automotive systems where reliable energy storage and filtering are required. Multilayer ceramic capacitors are among the most widely used passive components in modern electronics due to their small size, low cost, and excellent reliability. The GRM219R61E106MA12J belongs to Murata's general-purpose MLCC family, making it suitable for decoupling, filtering, and coupling applications in various circuit designs. These capacitors function by storing electrical charge between ceramic layers, enabling them to smooth voltage fluctuations, suppress noise, and maintain stable power delivery to sensitive circuits. The part designation provides important information about its characteristics. The "0805" package size (equivalent to 2.0mm × 1.25mm) represents a surface-mount form factor that is standard across the electronics industry. This compact footprint makes it ideal for high-density printed circuit board layouts where space constraints are critical. The surface-mount design allows for automated assembly processes, reducing manufacturing costs and improving production efficiency for volume applications. The "E" designation in the part number indicates the voltage rating class, while the "106" typically refers to the capacitance value in picofarad code. Murata's general-purpose MLCC lines are engineered to balance cost-effectiveness with performance, making them appropriate for non-critical filtering and decoupling roles where extreme precision or specialized characteristics are not required. Engineers commonly specify this exact part number for several reasons. Murata's reputation for consistent quality and reliability reduces the risk of field failures. The standard 0805 package size ensures compatibility with virtually all modern PCB assembly equipment and design tools. Additionally, the broad availability of general-purpose MLCCs from established manufacturers like Murata simplifies supply chain management and reduces design-to-production timeline risks compared to sourcing specialized components. This capacitor would typically be found in power supply circuits, signal coupling stages, EMI filtering sections, and decoupling applications on logic boards. Its versatility, proven performance history, and standardized form factor make it a dependable choice for engineers developing products ranging from consumer devices to industrial control systems. The component's widespread adoption across industries ensures long-term availability and established design practices within the engineering community.
