GRM31CC80E227ME11L

The GRM31CC80E227ME11L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading specialists in passive electronic components. This capacitor is part of Murata's GRM series, a comprehensive family of surface-mount ceramic capacitors widely used in consumer electronics, industrial equipment, and telecommunications infrastructure. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, serving critical functions in power supply filtering, signal coupling and decoupling, noise suppression, and frequency compensation across countless applications. The GRM31 designation indicates this is a compact surface-mount device with a 1206 package size (3.2mm × 2.5mm), making it suitable for space-constrained PCB layouts while maintaining robust performance characteristics. The "CC80" portion of the part number identifies the dielectric material and temperature characteristics of this capacitor. Murata's X7R-equivalent dielectric provides stable capacitance across a wide operating temperature range, making this component reliable for demanding industrial and automotive environments where temperature fluctuations are common. This stability is preferable to Y5V or Z5U dielectrics, which exhibit more significant capacitance variation with temperature. The "E227" element in the part number indicates the nominal capacitance value. This particular capacitor is designed for applications requiring moderate capacitance values, commonly found in decoupling networks, filtering stages, and signal path conditioning in digital and analog circuits. Engineers typically specify this exact part number when they require the combination of proven reliability, consistent performance, and proven availability that Murata's mainstream GRM series offers. The 1206 package size strikes a practical balance between board space efficiency and ease of handling during manufacturing and rework. Murata MLCCs in the GRM family are widely stocked, well-characterized across production lots, and benefit from extensive application notes and design guidance. This capacitor is suitable for applications including power distribution networks in microprocessors and microcontrollers, filtering in switched-mode power supplies, decoupling in digital logic circuits, and signal conditioning in analog measurement systems. The component's surface-mount construction enables automated assembly on modern PCBs, reducing manufacturing costs and improving reliability compared to through-hole alternatives. For engineers designing equipment requiring dependable passive components with stable performance across temperature variations and proven long-term availability, the GRM31CC80E227ME11L represents a standard choice that balances performance, size constraints, and supply chain predictability.
