GRM21BR71C224KA01L

The GRM21BR71C224KA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is designed for general-purpose applications across consumer electronics, industrial equipment, telecommunications, and automotive systems where reliable energy storage and filtering are required. Multilayer ceramic capacitors like this unit function as energy storage and filtering devices in electronic circuits. They suppress electrical noise, stabilize voltage supplies, couple and decouple AC signals, and smooth transient responses in power distribution networks. The compact size and high volumetric efficiency of MLCCs make them ideal for space-constrained designs where traditional electrolytic capacitors would be impractical. The "GRM21" prefix indicates this capacitor uses Murata's 1206 surface-mount package (3.2mm × 2.5mm × 1.25mm), a standard size widely adopted in modern PCB assembly. This package size strikes a practical balance between component miniaturization and ease of handling during automated manufacturing. The part is suitable for both wave soldering and reflow soldering processes commonly used in industrial production environments. The BR designation in the part number refers to the capacitor's dielectric material and temperature characteristics. Murata's BR series capacitors are formulated for reliable performance across a defined temperature operating range, making them suitable for applications that experience moderate thermal stress. The "224" code indicates the capacitance value through standard three-digit notation used across the industry. Engineers typically specify this exact part number when design requirements call for a compact ceramic capacitor in the 1206 package with specific electrical characteristics, temperature stability, and reliability standards established by Murata's quality and testing protocols. The GRM21 series benefits from decades of refinement in ceramic formulation and manufacturing processes, ensuring consistent performance across production batches. This consistency is particularly valuable in industrial and automotive applications where component variability must be minimized. The capacitor's construction using multiple ceramic layers provides advantages in terms of capacitance density and mechanical robustness compared to single-layer designs. This multilayer approach also contributes to the part's ability to handle the electrical stresses encountered in modern high-frequency switching power supplies and digital signal processing circuits. For applications requiring filtering, decoupling, or general energy storage in compact form factors, the GRM21BR71C224KA01L offers a proven solution with strong performance credentials and widespread industry acceptance.
