GRM2165C2A511JA01D

The GRM2165C2A511JA01D 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 surface-mount ceramic capacitors widely used across consumer electronics, industrial equipment, telecommunications, automotive systems, and medical devices. Multilayer ceramic capacitors are fundamental passive components used for energy storage, filtering, decoupling, and signal coupling in electronic circuits. The GRM2165C2A511JA01D is specifically designed for applications requiring stable capacitance performance in a compact form factor. Its designation indicates it falls within Murata's standard MLCC lineup, engineered to meet the demanding requirements of modern circuit design where space constraints and reliability are critical considerations. The "2165" in the part number denotes the physical package size, which is a standard metric format commonly encountered in industrial and consumer electronics manufacturing. This particular size represents a balance between capacitance density and ease of handling in automated assembly processes. Engineers often select components from this package family when designing boards that require moderate capacitance values without sacrificing valuable PCB real estate. The "511" segment of the part number indicates the nominal capacitance value within Murata's standardized coding system. This capacitor would be specified in applications where a specific capacitance value is needed for power supply filtering, AC coupling, timing circuits, or impedance matching. The component's construction uses ceramic dielectric material, which provides excellent frequency response characteristics and temperature stability across typical operating ranges found in industrial and commercial equipment. Murata's GRM series capacitors are known for consistent quality, reliable performance under thermal cycling, and compliance with industry standards including RoHS and AEC automotive specifications. Engineers specify exact part numbers like the GRM2165C2A511JA01D rather than generic alternatives because Murata maintains tight manufacturing controls, detailed performance characterization, and comprehensive technical documentation that enables precise circuit design and long-term supply chain stability. This component is particularly valuable in applications where thermal stability, low equivalent series resistance (ESR), and predictable aging characteristics matter—such as switched-mode power supplies, audio equipment, signal conditioning circuits, and industrial control systems. The specific voltage rating and temperature coefficient of this part make it suitable for general-purpose decoupling and energy storage roles in mid-range voltage applications typical of modern electronics.
