GRM31CR61C475MA01L

The GRM31CR61C475MA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This part belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial control systems, telecommunications equipment, and automotive applications. Multilayer ceramic capacitors are among the most commonly specified passive components in modern electronics. They provide stable capacitance in a compact form factor, making them essential for filtering, decoupling, coupling, and energy storage applications in circuit designs. The GRM series is engineered for reliable performance across a wide range of operating conditions and represents a cost-effective solution for high-volume manufacturing. The part number structure reveals key information about this specific component. The "GRM31" designation indicates this is a surface-mount ceramic capacitor in a standardized package size. The "C" in the part number typically refers to the dielectric material class, which determines the capacitor's temperature stability and performance characteristics. Murata designs these capacitors for applications where moderate temperature coefficients and stable performance are required during normal operating ranges. Engineers specify this particular part when they need a reliable, proven capacitor solution that balances cost, performance, and availability. The GRM31 series is popular in applications requiring decoupling and bypass filtering near integrated circuits, where board space is limited but capacitance requirements are moderate. These capacitors are also frequently used in power supply circuits, where they help stabilize voltage rails and suppress high-frequency noise. Murata's manufacturing quality and consistency make the GRM series a preferred choice for engineers designing equipment that must meet stringent reliability standards. The component's proven track record across millions of deployed devices means designers can confidently specify it without extensive qualification testing. This reduces development time and risk, particularly important in industries like automotive, industrial automation, and telecommunications where failure rates must be minimized. The compact surface-mount package enables efficient PCB layouts and supports automated assembly processes, further reducing production costs. For applications requiring multiple capacitors on a single board, standardizing on established GRM series parts streamlines procurement and inventory management across manufacturing operations. When selecting this capacitor, engineers should review the complete electrical specifications and performance curves relevant to their specific circuit requirements, including voltage rating, actual capacitance value, and operating temperature range, to ensure proper circuit performance and long-term reliability.
