GRM31MR61A106ME19L

The GRM31MR61A106ME19L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor belongs to Murata's GRM series, which is designed for general-purpose applications across consumer electronics, industrial equipment, telecommunications, and automotive systems. Multilayer ceramic capacitors are fundamental passive components used in nearly every modern electronic circuit. They function to store electrical charge, filter signals, smooth power supply ripples, couple and decouple AC signals, and stabilize voltage regulation circuits. The compact size and low cost of MLCCs make them the most widely used capacitor type in electronics manufacturing. The GRM31 package format indicates this is a compact surface-mount device with 1210 case dimensions (3.2mm × 2.5mm), making it suitable for high-density PCB applications where space is constrained. This size class offers a balance between capacitance value, voltage rating, and physical footprint—larger than smaller 0603 or 0805 packages but more compact than larger formats. Based on the part number coding, this capacitor is specified for general industrial and consumer applications. Murata's GRM series capacitors typically feature X7R dielectric material, which provides stable capacitance across temperature variations and voltage conditions, making them reliable for applications requiring consistent performance. The X7R classification indicates the capacitor maintains relatively stable capacitance characteristics across a broad temperature range, a critical requirement for circuits that must operate reliably in variable environmental conditions. Engineers typically specify this exact part number when designing circuits that require proven reliability, consistent electrical performance, and compatibility with established component sourcing. Murata's GRM series has extensive historical use data and proven field performance across countless applications, reducing design risk. The combination of compact package size, stable dielectric properties, and standard availability makes this part suitable for filtering, decoupling, and energy storage functions in power supplies, audio circuits, sensor interfaces, and signal processing applications. The 1210 package size also provides better capacitance per unit volume compared to smaller packages, which is advantageous when designers need specific capacitance values without excessive board space consumption. For applications requiring high reliability and temperature stability—such as industrial control systems, automotive electronics, or telecommunications infrastructure—engineers often prefer Murata's GRM series over alternative suppliers due to consistent quality and long-term availability. This component represents a standard choice for engineers designing robust, production-ready electronics requiring dependable passive component performance.
