GRM21B7U1A823JA01L

The GRM21B7U1A823JA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive components. This capacitor belongs to the GRM series, a widely-used family of general-purpose MLCCs designed for mainstream industrial and consumer electronics applications. Multilayer ceramic capacitors are fundamental passive components used in virtually every modern electronic circuit. They provide energy storage, filtering, decoupling, and coupling functions in power supplies, signal processing circuits, and control electronics. The GRM series specifically targets cost-sensitive applications where reliable performance and compact size are required, making it a popular choice for original equipment manufacturers and contract manufacturers worldwide. The part number structure indicates this capacitor uses a 0805 package size (2.0mm x 1.25mm), which is one of the most common surface-mount form factors in electronics manufacturing. This size represents a good balance between miniaturization and ease of handling in automated assembly processes. The 0805 package is small enough for dense PCB layouts yet large enough to maintain reasonable mechanical robustness and solderability. Based on the part number designation, this capacitor features a ceramic dielectric material with characteristics typical of general-purpose MLCCs. Murata's GRM series capacitors are designed to operate across a broad temperature range suitable for industrial equipment, consumer devices, and automotive applications. These capacitors are frequently specified in audio equipment, power management circuits, RF applications, and general-purpose filtering stages. Engineers typically choose MLCCs from established series like the GRM for several reasons: proven reliability in high-volume production, consistent performance across manufacturing batches, availability from multiple distribution channels, and cost-effectiveness compared to alternative capacitor technologies. The 0805 package size ensures compatibility with standard PCB assembly equipment and design tools, reducing development time and manufacturing complexity. The Murata GRM family has been in continuous production for decades, making these capacitors suitable for both new designs and replacement parts in existing equipment. This long-term availability and standardization across the industry means engineers can confidently specify these components knowing they will remain accessible throughout the product lifecycle. For applications requiring specific voltage ratings, capacitance values, or temperature coefficients, the GRM series offers numerous variants within the same package family, allowing design flexibility while maintaining supply chain consistency.
