GRM31MR71H474KA01K

The GRM31MR71H474KA01K is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor is designed for general-purpose filtering, decoupling, and signal coupling applications across a wide range of industrial and commercial electronics. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, used extensively in power supplies, audio equipment, RF circuits, computing devices, and industrial control systems. The GRM31 series designation indicates this is a mid-range capacitor in Murata's portfolio, positioned between smaller chip capacitors and larger discrete components. These capacitors are constructed from multiple layers of ceramic dielectric material with alternating metal electrodes, which allows manufacturers to achieve significant capacitance values in compact surface-mount packages. The part number's nomenclature reveals important characteristics. The "31" indicates a 1206-size package (3.2mm × 2.5mm), a standard SMD footprint that balances component density with ease of assembly and handling. This size is particularly popular in space-constrained applications where miniaturization matters but hand-rework capability is still required. The "MR" designation signals this capacitor operates with an X7R temperature-compensated dielectric, which provides stable capacitance across temperature ranges typically encountered in industrial environments. This temperature stability makes X7R capacitors more reliable than Y5V alternatives in applications where performance consistency is critical over varying operating conditions. Engineers typically specify Murata MLCCs for their consistent quality, reliable performance in high-volume manufacturing, and excellent availability through global distribution networks. Murata's manufacturing processes ensure low defect rates and repeatable electrical characteristics, reducing the risk of field failures and warranty claims. The brand is recognized for maintaining strict quality standards across production facilities worldwide. This capacitor type is commonly used in decoupling circuits near digital IC power pins, where it suppresses voltage transients and provides localized charge storage. It also serves in analog filter networks, timing circuits, and signal conditioning stages. The 1206 package offers practical advantages: it's large enough to handle adequate ripple current without excessive heating, yet small enough to enable dense PCB layouts typical of modern embedded systems and industrial equipment. When selecting this specific part, engineers benefit from Murata's extensive characterization data, established long-term supply agreements, and compatibility with automated assembly processes. The combination of proven reliability, consistent performance, and industry-standard packaging makes the GRM31MR71H474KA01K a practical choice for production environments where component quality directly impacts system uptime and customer satisfaction.
