GRM21BR72A104MAC4L

The GRM21BR72A104MAC4L 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 MLCCs designed for applications requiring reliable energy storage and filtering across a wide range of circuit configurations. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronics, used primarily for decoupling, bypassing, and noise filtering in power distribution networks. Engineers specify MLCCs in virtually every category of electronic equipment, from consumer devices to industrial control systems, telecommunications infrastructure, and automotive electronics. The GRM series in particular is widely selected for mainstream applications where cost-effectiveness and proven reliability are balanced with solid electrical performance. The "21" designation in the part number indicates this capacitor uses a 0805 package size (2.0mm x 1.25mm in metric dimensions), which represents one of the most common form factors in modern PCB design. This compact surface-mount package allows for high-density board layouts while remaining compatible with standard pick-and-place manufacturing equipment. The 0805 size strikes a practical balance between small footprint requirements and ease of manual rework if needed. The "BR" element in the designation refers to the dielectric material type used in this capacitor's construction. Murata's BR dielectric offers stable performance across typical industrial operating temperature ranges, making it suitable for applications where thermal stability is important but extreme temperature performance specifications are not required. This dielectric family is particularly popular in consumer and industrial electronics where cost and consistent behavior are priorities. Ceramic capacitors in the GRM family are known for their reliability, low ESR (equivalent series resistance), and stable capacitance characteristics. These properties make them excellent choices for high-frequency decoupling applications, power supply filtering, and signal coupling circuits. The multilayer construction provides capacitance density that allows designers to achieve required capacitance values in minimal board space. Engineers typically specify the GRM21BR72A104MAC4L series when they need a proven, widely-available capacitor solution that offers good performance-to-cost ratio for general-purpose filtering and decoupling. The extensive availability of Murata's GRM family across global distribution channels, combined with well-established manufacturing processes, makes these parts a reliable choice for production designs requiring long-term supply continuity and consistent quality.
