GRM316C81C225KA12D

The GRM316C81C225KA12D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This particular part belongs to the GRM series, which represents Murata's general-purpose ceramic capacitor line widely used across consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors function as energy storage and filtering devices in electronic circuits. They are constructed from alternating layers of ceramic dielectric material and metallic electrodes, compressed into a compact package. This construction allows manufacturers to achieve relatively high capacitance values in extremely small physical sizes, making MLCCs ideal for space-constrained applications where board real estate is premium. The part number designation indicates this capacitor uses a 1206 package format (also called 3216 in metric dimensions), which measures approximately 3.2mm by 1.6mm. This mid-range package size represents a common compromise between miniaturization and ease of handling during manufacturing and repair. The 1206 package remains popular in industrial and professional-grade equipment where components must withstand production soldering processes and occasional rework without excessive mechanical stress. The "C" designation in the part number identifies this as an X7R or Class II dielectric type. X7R capacitors are temperature-stable ceramic capacitors suitable for applications requiring consistent performance across a typical industrial temperature range. Unlike Class I capacitors, X7R types tolerate higher voltage and current stress, making them appropriate for power supply filtering, decoupling, and signal coupling applications in industrial control systems, power conversion equipment, and embedded electronics. Engineers select this specific part number when they require a reliable, temperature-stable capacitor in a standard 1206 package from an established manufacturer with proven field reliability. Murata's GRM series is known for consistent quality and availability in the global supply chain, which simplifies procurement and reduces obsolescence risk for long-term product designs. The combination of the 1206 package, X7R dielectric properties, and Murata's manufacturing standards makes this capacitor suitable for applications ranging from industrial automation controllers to power management circuits in telecommunications infrastructure. This component represents a fundamental building block in modern electronics, and its standardized nature means it can be easily substituted with equivalent parts from other manufacturers if required, though Murata's specific quality certifications and traceability may be preferred in mission-critical applications.
