GRM21BC7YA475KE11K

The GRM21BC7YA475KE11K is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a comprehensive family of general-purpose ceramic capacitors widely used across industrial, consumer, and automotive electronics applications. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronic circuits, serving critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and energy storage in timing circuits. The GRM series is engineered to deliver reliable performance in demanding environments, making it a trusted choice for engineers designing everything from industrial control systems to automotive electronics and consumer devices. The part number structure reveals key characteristics about this specific capacitor. The "21" in the designation indicates the physical package size, which is a standard form factor that balances compact dimensions with practical handling and assembly characteristics. This package size is widely compatible with automated assembly equipment and offers a good balance between board space constraints and electrical performance for general-purpose applications. Murata's GRM series capacitors are available in multiple package sizes and electrical ratings to accommodate diverse circuit design requirements. What makes engineers specify particular MLCC part numbers like the GRM21BC7YA475KE11K comes down to several factors working together: the specific capacitance value, voltage rating, temperature stability characteristics, and dielectric material composition. Different applications demand different combinations of these electrical properties. A capacitor suitable for power supply filtering in a 3.3V digital system will have different specifications than one used in high-voltage industrial equipment. The dielectric material type—indicated in the part number—directly affects how the capacitor behaves across temperature ranges and operating conditions, which is critical information for engineers designing circuits that must function reliably in real-world environments. Engineers selecting this component would typically be working on applications requiring moderate voltage and capacitance values with standard temperature performance. The proven reliability of Murata's manufacturing process, combined with the GRM series' extensive availability and well-established performance history, makes parts like this a practical specification choice for production designs where component availability and supply chain stability are important considerations. For engineers designing new equipment or updating existing designs, understanding the specific electrical and thermal characteristics of ceramic capacitors is essential for ensuring circuit stability, signal integrity, and long-term reliability.
