GRM2165C1H121JA01D

The GRM2165C1H121JA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This part belongs to Murata's GRM series, which represents a broad family of surface-mount ceramic capacitors designed for general-purpose applications across consumer electronics, industrial equipment, telecommunications, and automotive systems. Multilayer ceramic capacitors like this unit are fundamental building blocks in modern electronics, used for energy storage, filtering, decoupling, and signal coupling in virtually every type of circuit board. The GRM2165C1H121JA01D specifically uses a 1206 package size, a standard rectangular form factor measuring 3.2mm × 1.6mm × 1.6mm. This mid-range package size strikes a practical balance between component density and ease of handling during assembly, making it popular in both high-volume manufacturing and prototyping environments where both automated and manual placement may occur. The part number coding indicates this capacitor operates at 50V or higher voltage rating with a capacitance value in the 120pF range, typical for applications requiring high-frequency filtering, bypass functionality, or impedance matching in RF and analog circuits. Murata's GRM series capacitors are characterized by reliable performance across commercial and industrial temperature ranges, making them suitable for equipment operating in varied environmental conditions. Engineers typically specify capacitors from the GRM2165 line when they need dependable, cost-effective solutions with established supply chains and proven field history. The 1206 package format is particularly advantageous because it offers good mechanical stability, accommodates standard reflow soldering processes, and provides sufficient lead spacing for reliable PCB layout without requiring specialized equipment or techniques. This part is commonly found in power supply circuits, RF matching networks, audio equipment, measurement instruments, and industrial control systems. The choice of an MLCC in this package and from this manufacturer's range reflects design priorities around component availability, manufacturing simplicity, and performance predictability. Murata's quality standards and the GRM series' established presence in the market mean engineers can confidently integrate this part into designs without extensive qualification work, while procurement teams benefit from consistent global availability. For specific electrical parameters, operating conditions, or detailed application guidance, the manufacturer's official datasheet should be consulted, as component characteristics may vary based on specific tape and reel configurations or regional variants.
