GRM31MR71H104KA01L

The GRM31MR71H104KA01L 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 broad family of general-purpose ceramic capacitors widely used across consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors are fundamental passive components used in virtually every modern electronic device. They function to store electrical energy, filter signals, couple or decouple AC and DC circuits, and stabilize power supplies. The GRM series specifically is designed for mainstream applications where cost-effectiveness and reliability must be balanced with consistent performance across commercial and industrial temperature ranges. The part number structure indicates this component uses a 1206 package size, which is a standard Surface Mount Device (SMD) format measuring approximately 3.2mm by 1.6mm. This package size offers a practical middle ground—large enough to provide reasonable capacitance values and power handling capability, yet small enough for high-density circuit board layouts common in modern electronics. The 1206 format is one of the most widely encountered package sizes in industrial design, making inventory management and procurement straightforward for manufacturing operations. This particular variant is specified with X7R dielectric material, indicated by the "MR" designation in the part number. X7R ceramics provide stable capacitance across a wide temperature operating range, making them suitable for applications where temperature fluctuations are expected. This stability is particularly valuable in industrial environments, automotive systems, and telecommunications equipment where reliability over extended temperature ranges is critical. Engineers typically specify the GRM31MR71H104KA01L when they require a dependable, proven capacitor solution for general filtering, decoupling, and energy storage functions. The extensive availability of GRM series components, combined with Murata's reputation for consistent quality and performance, makes this part attractive for both prototype development and high-volume production runs. The 1206 package size ensures compatibility with standard manufacturing processes and rework procedures used in most contract manufacturers and internal production facilities. The component represents a standard solution rather than a specialized alternative, making it suitable for applications where established, proven performance is preferred over cutting-edge specifications. Its widespread use across industry means design engineers often have existing reference designs and application notes available, reducing development time and risk.
