GRM31A5C2H820JW01D

The GRM31A5C2H820JW01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors designed for widespread use across consumer, industrial, and automotive electronics. Multilayer ceramic capacitors function as energy storage devices and filtering components in electronic circuits. They work by storing electrical charge across multiple internal ceramic layers, allowing them to provide stable capacitance in compact form factors. The GRM series is engineered for reliability and cost-effectiveness, making these capacitors ideal for applications where consistent performance and miniaturization are important design considerations. The part designation contains encoded information about its specifications. The "31" in the part number indicates this is a 1206 package size, one of the most common surface-mount formats in modern electronics. This size provides a practical balance between component density and ease of handling during manufacturing. The "C2" prefix relates to the capacitor's temperature coefficient classification, which describes how the capacitance value changes across different operating temperatures—a key consideration for temperature-sensitive applications. Typical applications for GRM series capacitors include consumer electronics such as smartphones, tablets, and portable audio devices, as well as industrial control systems, power supplies, and telecommunications equipment. These capacitors are frequently used for power supply filtering, signal coupling and decoupling, timing circuits, and EMI suppression. Their small size and reliable performance make them particularly valuable in high-density PCB designs where space is at a premium. Engineers often select the GRM31A5C2H820JW01D specifically when they require a capacitor that meets particular voltage rating, capacitance value, and temperature stability requirements. Murata's GRM series has an established track record for consistency and quality across manufacturing batches, which is important for products requiring reliable performance over extended lifespans. The ceramic dielectric materials used in this series provide stable operation across a wide temperature range, suitable for both indoor and outdoor industrial environments. The standardized 1206 package format ensures broad compatibility with standard manufacturing equipment and assembly processes, reducing production complexity. For engineers designing new circuits or upgrading existing systems, this part offers proven reliability paired with readily available inventory at component distributors worldwide, minimizing supply chain risk for production builds.
