GRM31CR71C475MA01L

The GRM31CR71C475MA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers 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 infrastructure. Multilayer ceramic capacitors like this part are fundamental passive components found in virtually every modern electronic device. They serve critical functions including energy storage, signal coupling and decoupling, filtering, and noise suppression in power supply circuits. The MLCC construction—multiple layers of ceramic dielectric material with interleaved metallic electrodes—allows manufacturers to achieve significant capacitance values in compact physical packages. The part number designation provides key information about this specific variant. The "GRM31" prefix indicates this is a surface-mount component in a standard 1206 package size (3.2mm × 2.5mm), one of the most common form factors in modern electronics manufacturing. The "CR71" portion of the designation relates to the capacitor's dielectric composition and performance characteristics, typically indicating a ceramic formulation suited for general industrial and commercial applications. The "C475" element specifies the capacitance value, while the "MA01L" suffix indicates RoHS compliance and tape-and-reel packaging format suitable for automated assembly. Engineers and procurement professionals specify Murata MLLCs like the GRM31CR71C475MA01L for several important reasons. Murata's manufacturing processes deliver consistent quality and reliability, with tight tolerances and excellent long-term stability compared to many alternative suppliers. The 1206 package size offers an optimal balance between component density and ease of handling in manufacturing environments. This particular variant is especially common in applications requiring moderate to higher capacitance values in space-constrained designs. Typical applications include filtering circuits in switching power supplies, decoupling capacitors on digital logic boards, timing circuits, and coupling stages in analog signal conditioning. Industrial equipment, IoT devices, automotive electronics, and renewable energy systems frequently incorporate capacitors from this family. The GRM31CR71C475MA01L represents a standard-performance, proven solution for designers who prioritize reliability and supply chain continuity. Its widespread use across industries means substantial design documentation and application notes are readily available, reducing development risk for engineers integrating this component into new designs.
