GRM21BR61C105KA01L

The GRM21BR61C105KA01L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, a leading supplier of passive electronic components. This capacitor belongs to Murata's GRM series, which is widely recognized in the electronics industry for reliable performance across consumer, industrial, and automotive applications. Multilayer ceramic capacitors like this model are fundamental building blocks in modern electronic circuits. They function to store electrical energy, filter noise, couple or decouple signals, and stabilize voltage in power supply circuits. The GRM series specifically represents a cost-effective yet dependable option for general-purpose capacitance requirements in compact designs where space constraints are common. The "21" designation in the part number indicates the physical package size—specifically a 0805 metric package (roughly 2.0mm × 1.25mm × 1.25mm). This compact form factor makes the component ideal for surface-mount assembly on printed circuit boards, particularly in space-constrained applications like consumer electronics, telecommunications equipment, and industrial control systems. The small footprint allows designers to achieve high component density without sacrificing reliability. Murata's GRM series capacitors are engineered for stable performance across a range of operating conditions. These components feature X7R dielectric material, which provides stable capacitance performance over typical industrial and consumer temperature ranges, making them suitable for both room-temperature and moderately elevated ambient conditions. This temperature stability is critical for applications where circuit performance must remain consistent regardless of environmental fluctuations. Engineers typically specify this exact part number when their design requires a general-purpose capacitor that balances cost, reliability, and performance. The GRM21 package offers versatility—it appears in everything from power management circuits in microcontrollers to filtering stages in audio amplifiers and signal conditioning circuits. The widespread availability and consistent quality of Murata's GRM series mean shorter lead times and reduced obsolescence risk compared to lesser-known alternatives. The robustness of Murata's manufacturing process, combined with the proven track record of the GRM family, makes this component a preferred choice for engineers who need predictable behavior and long-term supply stability. Whether designing medical devices, industrial automation equipment, or consumer products, specifying established MLCC solutions from recognized manufacturers like Murata reduces technical risk and simplifies procurement. For applications requiring specific electrical characteristics, detailed technical documentation should be consulted to confirm this part meets your circuit's exact capacitance, voltage, and tolerance requirements.
