GRM31CR61E106MA12L

The GRM31CR61E106MA12L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is designed for general-purpose applications across industrial, automotive, telecommunications, and consumer electronics sectors where reliable energy storage and signal filtering are required. Multilayer ceramic capacitors like this model function as energy storage and filtering elements in electronic circuits. They smooth voltage fluctuations, filter high-frequency noise, decouple power supplies, and stabilize signal integrity in digital and analog applications. The compact size and high volumetric efficiency of MLCCs make them ideal for modern circuit board designs where space is at a premium. This particular part number belongs to Murata's GRM series, which represents a well-established family of general-purpose capacitors widely specified across the industry. The "31" in the part number indicates the package size—specifically a 1206 metric package (3.2mm x 1.6mm), which is one of the most common surface-mount capacitor formats. This standard size makes the component compatible with automated assembly equipment and allows for straightforward replacement or retrofitting in existing designs. The GRM31CR series designation suggests this is a ceramic X7R dielectric type capacitor, a material composition known for stable capacitance performance across a wide temperature range. X7R dielectrics are preferred in applications requiring consistent performance in varying thermal environments, making them suitable for industrial and automotive use where temperature fluctuations are common. Engineers typically specify this exact part when they need a proven, widely-available ceramic capacitor in a standard package size with predictable electrical characteristics and proven long-term reliability. The established reputation of Murata's GRM series means extensive application notes, design guidance, and field history are available, reducing design risk. The 1206 package size provides flexibility—it's small enough for modern compact designs yet large enough to handle reasonable power levels without thermal concerns. This part is commonly found in power supply decoupling networks, signal conditioning circuits, impedance matching networks, and general filtering applications throughout industrial equipment, control systems, telecommunications infrastructure, and consumer devices. Its standardized format and broad applicability make it a reliable choice for engineers seeking a dependable ceramic capacitor solution that balances performance, availability, and cost-effectiveness.
