GRM21BC71E475ME11K

The GRM21BC71E475ME11K is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading capacitor producers. This component belongs to Murata's GRM series, which is widely recognized in industrial and consumer electronics applications for delivering reliable performance across demanding environments. Multilayer ceramic capacitors like this part are fundamental passive components used in virtually every modern electronic circuit. They function to store electrical charge, filter noise, couple or decouple signals, and stabilize voltage in power supply circuits. The compact form factor and high volumetric efficiency of MLCCs make them ideal for space-constrained applications where designers need to minimize board footprint while maintaining robust electrical performance. The "21" designation in the part number indicates this capacitor uses a 0805 metric package size (2.0mm x 1.25mm), making it suitable for both surface-mount assembly on standard printed circuit boards and automated manufacturing processes. This package size represents a common middle ground in MLCC selection, offering a balance between component density and ease of handling during production. Murata's GRM series capacitors are specified across diverse industrial sectors including telecommunications infrastructure, automotive electronics, industrial control systems, LED lighting, and renewable energy equipment. These capacitors perform reliably in power management circuits, signal integrity applications, and electromagnetic interference filtering where consistent performance is critical. Engineers typically choose this specific part number when they require an MLCC that meets particular voltage, capacitance, and temperature coefficient specifications within the GRM family's performance envelope. Murata's manufacturing processes ensure tight tolerance control and consistent electrical characteristics across production batches, which is important for applications where component-to-component variation must be minimized. The ceramic material composition and internal multilayer construction of GRM series capacitors provide stable capacitance over temperature ranges commonly encountered in industrial equipment. This stability, combined with low equivalent series resistance (ESR) characteristics typical of modern MLCCs, makes these components suitable for high-frequency circuits and applications requiring minimal ripple current effects. Designers often cross-reference multiple capacitor manufacturers' datasheets when selecting components, and Murata's GRM series frequently emerges as a preferred alternative due to proven field reliability, consistent availability, and performance that meets or exceeds comparable alternatives from other manufacturers. For engineers working on designs requiring replacement or upgrade of existing GRM capacitors, specifying this exact part number ensures compatibility and maintains the validated performance characteristics established during original design qualification.
