GRM31MR61A225KA01L

The GRM31MR61A225KA01L 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 use in demanding industrial, consumer electronics, and telecommunications applications where reliable energy storage and filtering are critical to circuit performance. Multilayer ceramic capacitors like this model consist of alternating layers of ceramic dielectric material and metal electrodes, all stacked and sintered into a compact package. The primary function of this component is to store electrical charge and filter unwanted noise from power supplies and signal lines. Engineers specify MLCCs in countless applications including power distribution networks, analog filtering stages, coupling and decoupling circuits, and high-frequency signal conditioning. The GRM31MR61A series belongs to Murata's general-purpose MLCC lineup, characterized by a 1206 package size (3.2 mm × 2.5 mm), which represents a common middle ground in the surface-mount capacitor world. This package size offers a practical balance between component density and ease of handling during manufacturing, making it suitable for automated assembly processes used in most modern electronic production facilities. The "61" designation in the part number indicates this capacitor is rated for 10-volt operation, a typical specification for circuits operating from standard logic supply voltages or modestly elevated power rails. The "225" in the part number denotes a capacitance value in the low-microfarad range, suitable for general decoupling, smoothing, and filtering applications where moderate energy storage is needed. The "A" suffix typically indicates standard tolerance and temperature coefficient characteristics, making this a general-purpose grade rather than a specialized high-precision or extreme-temperature variant. Murata's MR series MLCCs are known for consistent quality, stable performance across commercial temperature ranges, and reliable behavior in manufacturing-intensive environments. These capacitors are widely specified in consumer electronics, industrial control systems, automotive electronics (non-critical functions), and telecommunications infrastructure where cost-effectiveness and proven reliability are valued alongside technical performance. Engineers typically choose this specific part number when they need a cost-effective, readily available general-purpose capacitor in a standard package size, with mainstream voltage and capacitance ratings. The combination of established manufacturing processes, proven field reliability, and broad availability makes this component a practical default choice for mid-range voltage applications where more specialized high-capacitance or high-temperature variants are not required.
