GRM21BR72A473KA01L

The GRM21BR72A473KA01L 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 broad family of general-purpose ceramic capacitors designed for widespread use across consumer, industrial, and telecommunications applications. Multilayer ceramic capacitors are among the most widely used passive components in modern electronics. They function to store and release electrical energy, filter noise, decouple power supplies, and stabilize voltage in circuits. The GRM21BR72A473KA01L belongs to the size 0805 package category (roughly 2.0mm × 1.25mm), making it suitable for compact PCB designs where space is a premium consideration. This package size represents a standard in contemporary surface-mount technology, balancing component density with ease of manufacturing and rework. The part designation indicates this capacitor operates at 16 volts, with a capacitance value in the 47 microfarad range and features X7R dielectric material. X7R dielectrics are temperature-stable formulations commonly specified for applications requiring predictable performance across industrial temperature ranges, typically from -55°C to +125°C. This makes the component suitable for both consumer-grade and industrial-rated equipment. Engineers typically specify capacitors from the GRM series in decoupling applications near integrated circuits, where they suppress voltage transients and noise on power distribution networks. They are equally common in analog and mixed-signal circuits, including audio equipment, power management modules, LED drivers, and general instrumentation. The 0805 package size is particularly popular in cost-sensitive production environments where automated assembly equipment and standard PCB layouts are employed. The choice of this specific part number over alternatives often depends on several factors: the need for a proven, widely-available component from a trusted manufacturer; compatibility with existing supply chains and design standards; the specific voltage and capacitance combination required by the circuit design; and the reliability requirements of the end application. Murata's GRM series has been in production for many years, ensuring long-term availability and consistent quality across manufacturing batches. For applications requiring high-reliability operation, industrial certifications, or extended temperature ranges, engineers may reference this part as a standard building block in power supply design, microcontroller decoupling networks, and signal conditioning circuits across industrial automation, telecommunications infrastructure, and automotive electronics platforms.
