GRM31MR71H394KA01L

The GRM31MR71H394KA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a broad family of surface-mount ceramic capacitors designed for general-purpose industrial and commercial applications. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronic circuits, serving functions such as filtering, coupling, decoupling, and bypass applications. They store electrical energy in an electric field between multiple ceramic layers, offering high volumetric efficiency and reliable performance across a wide range of environmental conditions. The part number coding indicates specific electrical characteristics. The "31" in the designation refers to the physical package size, which is a 1206 package format (3.2mm × 2.5mm). This size represents a common middle ground in surface-mount capacitor selection, offering adequate capacitance for many circuits while remaining compact enough for dense PCB layouts. The "MR" prefix identifies this as part of Murata's general-purpose ceramic capacitor line rated for mid-range voltage applications. The numeric sequence "394" relates to the capacitance value, while "KA01L" indicates environmental specifications, temperature characteristics, and RoHS compliance. Engineers typically specify components from the GRM series when designing power supply circuits, signal processing stages, RF applications, and consumer electronics that require cost-effective, reliable capacitors. These capacitors exhibit stable performance across industrial temperature ranges and are suitable for both automated assembly and high-volume manufacturing processes. The MLCC format eliminates the need for through-hole drilling, making them ideal for modern surface-mount technology production lines. The choice of this specific part over alternatives generally depends on matching the required capacitance value, voltage rating, and temperature stability class to the application's demands. Murata's GRM series is known for consistent quality, proven long-term reliability, and widespread design compatibility. Engineers appreciate these capacitors for applications ranging from consumer electronics to industrial control systems, where performance must be predictable over extended operating lifespans and varied environmental conditions. For exact electrical specifications, operating temperature ranges, and detailed performance characteristics, consultation of the manufacturer's datasheet is recommended. The GRM31MR71H394KA01L is readily specified in design applications where Murata MLCCs are already qualified and trusted.
