GRM319R61K225KA12D

The GRM319R61K225KA12D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the leading producers of passive components for electronics. This capacitor belongs to Murata's GRM series, which represents a comprehensive family of surface-mount ceramic capacitors designed for high-reliability applications across industrial, automotive, telecommunications, and consumer electronics sectors. Multilayer ceramic capacitors like this component are fundamental building blocks in modern circuit design. They function as energy storage devices, signal coupling elements, noise filtering components, and voltage stabilization aids in power supply circuits. The compact form factor and excellent electrical characteristics of MLCCs make them indispensable in densely populated printed circuit boards where space constraints are critical. The GRM319 designation indicates this is a 1206-sized component, measured in metric dimensions (3.2mm × 1.6mm × 0.8mm). This size represents a practical middle ground in surface-mount capacitor selection—larger than smaller 0603 packages but more compact than 1210 alternatives. The 1206 package is widely used in applications requiring moderate capacitance values with reasonable component density. The "K" designation in the part number typically refers to the dielectric material class used in the capacitor's construction. Murata's GRM series offers various dielectric formulations optimized for different performance characteristics, balancing capacitance stability, temperature performance, and voltage rating according to application requirements. Engineers often select specific dielectric classes based on whether their circuit prioritizes temperature stability, high capacitance per unit volume, or wide operating temperature range. This component is particularly suitable for applications requiring reliable passive component performance in demanding environments. Industries commonly specifying components from this family include automotive electronics, industrial control systems, power conversion circuits, RF and microwave applications, and consumer electronics where both performance and long-term reliability are essential. The GRM series has established a strong reputation for quality and consistency, making it a preferred choice for engineers designing products with extended service life requirements. Engineers typically specify the exact GRM319R61K225KA12D part number when they have calculated specific capacitance and voltage requirements for their circuit and need the proven reliability and consistent performance characteristics associated with Murata's quality standards. The part number's structure ensures clear identification of the component's electrical class and packaging, reducing the risk of substitution errors in manufacturing and supporting design documentation requirements in regulated industries.
