GRM31CR61C106KA88L

The GRM31CR61C106KA88L 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 to store and release electrical energy in circuits. They serve critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and timing applications. The compact size and reliability of MLCCs make them ideal for modern circuit boards where space is constrained and high-volume manufacturing is required. The GRM31 designation indicates this capacitor uses a 1206 package size (3.2mm × 2.5mm), which represents a standard surface-mount format widely recognized across the electronics industry. This package size offers a balance between compact dimensions suitable for dense PCB layouts and sufficient physical robustness for automated assembly processes and field applications. The 1206 package is one of the most commonly specified sizes for general-purpose capacitor applications in industrial and commercial equipment. The "CR" portion of the part number indicates this capacitor features an X7R dielectric material. X7R capacitors provide relatively stable capacitance performance across a wide temperature operating range, making them suitable for applications where temperature variations are expected. This characteristic distinguishes them from Y5V or other dielectric types that may exhibit greater capacitance variation with temperature, allowing engineers to select X7R capacitors when temperature stability is a design requirement. Engineers typically specify the GRM31CR61C106KA88L when designing circuits requiring a capacitor with the 1206 form factor and X7R temperature stability characteristics. This part would be selected for applications such as DC-DC converter filtering, power distribution networks, signal conditioning circuits, or industrial control systems where reliable performance across operating temperature ranges is important. The Murata GRM series represents mature, well-established technology with proven field reliability across millions of deployed units. This long production history and established supply chain make parts like the GRM31CR61C106KA88L attractive for both new product designs and replacement/maintenance applications in existing equipment.
