GRM21BR71E475MA73L

The GRM21BR71E475MA73L is a multilayer ceramic capacitor 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 surface-mount ceramic capacitors designed for reliable performance across diverse industrial and commercial applications. Multilayer ceramic capacitors are fundamental passive components used to store electrical energy, filter signals, decouple power supplies, and stabilize voltage in electronic circuits. The GRM21BR71E475MA73L specifically serves these functions in compact form, making it suitable for space-constrained applications where miniaturization is critical without sacrificing performance or reliability. The part number designation itself contains important information about the component's specifications. The "21" in the series name indicates this capacitor uses a 1206 metric package size (3.2 × 2.5 mm), which represents a standard footprint widely adopted in surface-mount assembly. This package size offers a practical balance between component density and handling ease during manufacturing, making it popular in modern PCB designs where space efficiency matters. The GRM21BR71E475MA73L is engineered for general-purpose applications across consumer electronics, telecommunications equipment, automotive systems, medical devices, and industrial control circuits. Engineers commonly specify capacitors from this series in power supply filtering stages, signal coupling and decoupling networks, and timing circuits where stable, reliable performance is essential. Murata's GRM ceramic capacitor series is known for consistent quality, long-term stability, and cost-effectiveness, positioning these components as standard choices for high-volume manufacturing. The series demonstrates excellent frequency characteristics and low equivalent series resistance, which proves valuable in applications requiring clean power delivery or high-speed signal integrity. When selecting the GRM21BR71E475MA73L over alternative capacitors, engineers consider Murata's manufacturing reputation, the compact 1206 package footprint, and the specific electrical characteristics encoded in the part number. This capacitor integrates reliably into existing designs where this package and performance class have been validated, reducing design risk and qualification time. The ceramic construction provides robustness in challenging environments, with good resistance to mechanical stress and thermal cycling—important for applications in industrial settings, automotive underhood locations, or equipment experiencing temperature fluctuations. The surface-mount design eliminates the need for through-hole drilling, supporting modern automated assembly processes and reducing overall manufacturing costs. For engineers evaluating passive component options, the GRM21BR71E475MA73L represents a proven, readily available solution from an established manufacturer, suitable for numerous applications where this package size and performance characteristics align with circuit requirements.
