GRM21BR71C474KA01K

The GRM21BR71C474KA01K 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 designed for widespread industrial and commercial applications. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, used to store and release electrical energy, filter signals, and stabilize power supplies across countless devices and systems. The GRM21BR71C474KA01K specifically combines reliable performance with a compact footprint, making it suitable for applications where space efficiency and cost-effectiveness are important design considerations. The part number itself encodes key information about the component. The "21" designation indicates this capacitor uses a 0805 metric package size (2.0mm x 1.25mm), which is a surface-mount form factor commonly found on circuit boards in industrial equipment, consumer electronics, telecommunications hardware, and automotive systems. This standardized package allows for automated assembly and compatibility with standard manufacturing processes used across the electronics industry. The "BR7" code indicates specific characteristics related to the capacitor's dielectric material and electrical class, which determines its temperature stability and voltage characteristics. The "1C" segment references the voltage rating, while the "474K" designation indicates the capacitance value and tolerance specification. The "A" suffix denotes the specific termination type and environmental robustness level, while "01K" provides manufacturing date code information. Engineers typically specify this exact part number when they need a capacitor that balances several practical requirements: a proven, widely-available component from a reputable manufacturer; compatibility with standard PCB assembly processes; reliable performance across typical industrial temperature and humidity ranges; and cost-effective procurement for volume production. Murata's GRM series capacitors are recognized throughout the electronics industry for consistent quality and long-term availability. Common applications for capacitors in this class include decoupling and bypass filtering in digital circuits, power supply stabilization, signal coupling and blocking, EMI suppression, and timing circuit applications. Because the GRM series offers multiple variants across different capacitance values, voltage ratings, and temperature characteristics, engineers can select the precise variant needed for their specific circuit requirements while maintaining design standardization. For applications requiring high reliability, established supplier relationships, or compliance with specific industrial quality standards, specifying this particular Murata part provides confidence in long-term component availability and consistent performance characteristics.
