GRM31MR71E225KA93L

The GRM31MR71E225KA93L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers 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, telecommunications, industrial control systems, and automotive applications. Multilayer ceramic capacitors like this one are fundamental building blocks in modern electronics, serving critical functions in power supply filtering, signal coupling and decoupling, noise suppression, and frequency compensation circuits. The GRM31MR71E225KA93L uses a ceramic dielectric material sandwiched between multiple internal electrode layers, allowing manufacturers to achieve relatively high capacitance values in a compact physical footprint. This design makes MLCCs ideal for applications where board space is limited and miniaturization is essential. The part number itself encodes important information about the component's specifications. The "31" in the designation indicates this is a 1206-size package, a standard surface-mount form factor measuring 3.2mm by 1.6mm. This size sits in the middle range of common MLCC packages, offering a practical balance between handling ease and component density. The "MR" designation suggests this capacitor uses a standard X7R or similar dielectric material, which provides stable capacitance performance across a moderate temperature range—typical for general industrial and commercial applications rather than high-reliability military use. Engineers typically specify the GRM31MR71E225KA93L when they need a dependable ceramic capacitor for mainstream applications where cost-effectiveness and proven reliability matter. The 1206 package size makes it straightforward to work with using standard surface-mount assembly equipment and techniques. This part is commonly found in power management circuits, communication modules, industrial instrumentation, and consumer product designs where the performance characteristics of Murata's established GRM family meet application requirements. Compared to alternative solutions, this component offers the manufacturer's long-standing quality reputation and availability through multiple distribution channels. Engineers who have validated previous generations of Murata capacitors in similar applications often continue specifying parts from this family due to consistency and interchangeability. The GRM31MR71E225KA93L represents a mature, well-established solution rather than a specialized high-performance device, making it suitable for volume production runs where standardization and supply chain reliability are practical considerations.
