GRM2165C1H821JA01D

The GRM2165C1H821JA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading capacitor suppliers. This component belongs to Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used in consumer electronics, industrial equipment, telecommunications infrastructure, and automotive applications. MLLCs like this part are fundamental passive components that store and release electrical energy, serving critical functions in power supply filtering, signal coupling, decoupling, and noise suppression across countless circuit designs. The GRM series is known for reliability and consistent performance in mainstream applications where cost-effectiveness and proven quality are essential. The part number structure indicates this capacitor uses a 0805 package size (2.0mm × 1.25mm), which is one of the most common Surface Mount Device (SMD) footprints in modern electronics manufacturing. This compact package allows for high-density circuit board layouts while remaining large enough for reliable hand soldering and automated assembly. The 0805 format strikes a practical balance between miniaturization and ease of handling in production environments. This particular part features a ceramic dielectric material rated for standard voltage and temperature operating ranges typical of general industrial and consumer applications. Murata's quality control processes ensure these capacitors maintain stable capacitance values across their operating temperature ranges, making them suitable for equipment that experiences moderate temperature fluctuations. Engineers commonly specify Murata MLCC components for their proven long-term reliability, consistent electrical performance over product lifespans, and extensive availability through global distribution networks. The GRM series specifically appeals to design teams building cost-sensitive products in high volumes where supply chain stability and manufacturing compatibility are important considerations. The 0805 package format also simplifies board design and reduces manufacturing complexity compared to smaller packages. Applications for components in this family include power management circuits, signal processing modules, RF applications, and general decoupling networks in digital logic and analog circuits. The robust construction of Murata's ceramics makes them well-suited to industrial environments where temperature cycling, vibration, or moisture exposure may occur. For engineers evaluating alternatives, Murata's GRM series offers a mature design with extensive field history, comprehensive technical documentation, and reliable availability. The standardized 0805 package ensures compatibility with established manufacturing processes and inventory systems. When specifications call for proven performance, consistent quality, and straightforward sourcing, this part number represents a dependable choice for circuit designers across multiple industries.
