GRM2165C1H122JA01D

The GRM2165C1H122JA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's largest and most respected capacitor producers. This component belongs to Murata's GRM series, which represents a broad family of general-purpose MLCCs designed for reliable performance across consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors like this model are among the most widely used passive components in modern electronics. They function as energy storage devices, filtering elements, and signal coupling/decoupling components in circuits. The GRM series is engineered to deliver stable capacitance values across a wide range of operating conditions, making these capacitors suitable for applications where consistent electrical performance is critical. This particular part number follows Murata's standard coding convention, with the "GRM" prefix indicating the general-purpose MLCC category. The component features a 1206 package size (0.126 × 0.063 inches), which is one of the most common surface-mount form factors. This standardized package size makes the component compatible with automated manufacturing equipment used in high-volume production environments, while remaining compact enough for space-constrained designs. The "C1H" designation in the part number indicates the component operates at 50V rated voltage, making it suitable for standard industrial and consumer-grade power supply circuits, audio equipment, and mid-voltage applications. The component utilizes Murata's ceramic dielectric formulation, which provides good stability and reliability for general-purpose filtering and coupling applications. Engineers typically specify Murata GRM series capacitors when they require proven, widely available components with established supply chains and consistent performance from established production facilities. The GRM family benefits from extensive documentation, proven reliability data across millions of units in field service, and compatibility with standard manufacturing processes. This makes them a lower-risk choice compared to lesser-known alternatives, particularly in mission-critical applications or high-volume productions where component availability and consistency directly impact manufacturing schedules. The 1206 package size offers practical advantages for both automated assembly and manual rework, which is valuable during prototyping and repair scenarios. Murata MLCCs in this series are commonly found in power management circuits, filtering stages, signal integrity applications, and coupling/decoupling roles throughout industrial control systems, test equipment, and embedded systems. This component represents a standard, reliable choice for engineers seeking proven performance in general-purpose capacitor applications where mid-voltage ratings and compact packaging are required.
