GRM31CR72J223KW03L

The GRM31CR72J223KW03L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a comprehensive range of general-purpose MLCCs designed for mainstream industrial and consumer electronics applications. Multilayer ceramic capacitors are fundamental passive components used in virtually every modern electronic circuit. They provide energy storage, filtering, decoupling, and signal coupling functions across power supplies, audio circuits, RF applications, and digital logic boards. The GRM series specifically targets cost-conscious applications where performance and reliability are required without premium specifications. The part number structure reveals key details about this component's specifications. The "31" in the designation indicates a 1206 package size, which is a standard surface-mount format measuring approximately 3.2mm by 1.6mm. This package size is widely used in industrial and commercial electronics because it offers a practical balance between component density and ease of handling during automated assembly processes. The "CR72" notation refers to the dielectric material class and voltage rating within Murata's classification system, typically indicating a ceramic dielectric suitable for general-purpose filtering and decoupling applications. Engineers select this specific part number for applications requiring reliable capacitive performance in standard industrial environments. The GRM31 package is particularly popular in cost-sensitive designs where component miniaturization is beneficial but where ultra-small packages are unnecessary. Common application areas include power supply filtering stages, signal path decoupling on PCBs, noise suppression in digital circuits, and AC coupling applications in audio and instrumentation equipment. The MLCC construction provides several inherent advantages: excellent frequency response characteristics, minimal self-inductance compared to older film or electrolytic capacitor technologies, good temperature stability across typical operating ranges, and proven long-term reliability in industrial settings. Murata's manufacturing quality ensures consistent performance and predictable behavior in design calculations. Designers often specify this particular part when they require a standard, proven component with excellent availability and established supply chains. The GRM31CR72J223KW03L represents a mature product line with extensive design support resources, application notes, and field history. This makes it an ideal choice for industrial equipment, telecommunications infrastructure, automotive electronics (non-safety-critical applications), and general commercial electronics where reliability and cost-effectiveness are equally important priorities.
