GRM21BR71H563KA01L

The GRM21BR71H563KA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This part belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors designed for mainstream industrial and commercial electronics applications. Multilayer ceramic capacitors like this unit are fundamental passive components found in virtually every modern electronic device. They serve critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and timing circuit applications. The compact package format and reliability of ceramic capacitors make them the dominant choice for high-volume manufacturing across consumer electronics, telecommunications, automotive electronics, industrial control systems, and medical devices. The GRM21 designation indicates this capacitor uses a 0805 metric package (2.0mm × 1.25mm footprint), which represents one of the most widely used surface-mount sizes in modern PCB design. This mid-sized package strikes a practical balance between component density and ease of handling during assembly. The 0805 format is compatible with standard pick-and-place equipment and reflow soldering processes used in virtually all contract manufacturers and OEM assembly facilities. The "BR" in the part number identifies this as a capacitor with a mid-range dielectric class, which provides stable capacitance across typical industrial temperature ranges with reasonable voltage derating characteristics. This makes BR-class capacitors suitable for general filtering and coupling applications where moderate temperature stability is required but extreme precision is not critical. Murata's GRM series capacitors are specifically engineered for reliability in industrial environments. They exhibit low equivalent series resistance (ESR) and equivalent series inductance (ESL) compared to older ceramic capacitor generations, making them effective for modern high-frequency switching power supplies and digital circuits. The series is RoHS compliant and suitable for lead-free soldering processes. Engineers commonly specify Murata GRM capacitors when they require proven reliability, consistent supply availability, and proven compatibility with standard manufacturing processes. The combination of the established 0805 package format, mid-range dielectric performance, and Murata's reputation for quality control makes this part a standard choice for designers who need a dependable general-purpose capacitor without specialized performance requirements or extreme environmental demands. The part's widespread use in production electronics means design resources, application notes, and manufacturing support are readily available.
