GRM155R61E105MA12D

The GRM155R61E105MA12D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor belongs to the GRM series, which represents Murata's established line of general-purpose ceramic capacitors designed for reliable performance across a wide range of industrial and commercial applications. Multilayer ceramic capacitors like this component are fundamental building blocks in modern electronics, used for energy storage, filtering, coupling, decoupling, and signal conditioning in circuits. The GRM155 designation indicates this is a compact surface-mount device in the 0402 package size (1.0mm x 0.5mm), making it suitable for high-density PCB designs where space constraints are critical. This small form factor allows engineers to integrate multiple capacitors into confined areas without compromising circuit functionality. The "MA12D" suffix in this part number identifies the specific characteristics of this capacitor variant. Murata's GRM series capacitors in this configuration are typically specified for applications requiring stable performance across moderate temperature ranges and voltage levels. These capacitors are commonly found in consumer electronics, telecommunications equipment, automotive systems, industrial control boards, and portable instrumentation where compact size and reliable filtering are essential. Ceramic capacitors from the GRM series are particularly valued in decoupling applications, where they suppress voltage transients and high-frequency noise near integrated circuits and power supplies. Their low equivalent series resistance (ESR) and inductance (ESL) make them effective for power supply bypassing, especially in digital logic circuits and microprocessor-based systems. Engineers also specify these capacitors in analog signal paths for AC coupling and filtering, taking advantage of their predictable frequency response characteristics. The robust construction of Murata's ceramic capacitors provides excellent reliability in demanding environments. The multilayer design offers good mechanical stability and resistance to thermal shock, important considerations for industrial applications subject to temperature cycling or vibration. The standardized 0402 package size ensures compatibility with modern automated assembly equipment and standard component placement machines found in manufacturing facilities worldwide. When selecting this specific part number, engineers are choosing a component with established manufacturing standards, consistent quality control, and proven performance history across numerous production designs. The combination of small package size, proven reliability, and Murata's reputation for quality makes this capacitor a practical choice for applications where space efficiency and dependable operation are both required.
