GRM31A5C3A101JW01D

# Product Description The GRM31A5C3A101JW01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive electronic components. This capacitor is part of Murata's GRM series, which represents a broad family of general-purpose ceramic capacitors widely used in consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronic circuit design. They function as energy storage and filtering components, smoothing voltage ripples, decoupling power supplies, and blocking DC while passing AC signals. Their small form factor, reliability, and cost-effectiveness make them essential in virtually every electronic device manufactured today. The GRM31 designation indicates this capacitor uses a 1206 surface-mount package, a standard industry size that balances ease of automated assembly with reasonable capacitance values. This package size is popular in space-constrained applications where engineers need moderate capacitance without requiring larger, more expensive components. The 1206 package is compatible with standard pick-and-place assembly equipment used in manufacturing facilities worldwide. Murata's GRM series capacitors are characterized by stable performance across typical industrial temperature ranges and operating conditions. These components are designed for general-purpose applications rather than specialized high-reliability or high-temperature extreme environments, making them ideal for mainstream consumer and industrial electronics where cost and availability are practical considerations. Engineers typically specify this exact part number when they need a reliable, readily available capacitor from an established manufacturer with consistent supply chain availability. Murata's quality standards and worldwide distribution ensure that designs using GRM series components can move into production with minimal risk of component obsolescence or supply disruption—a critical factor in production environments. The specific variant designation in the part number indicates particular electrical characteristics, including capacitance value, voltage rating, and tolerance class. These specifications are selected by design engineers based on circuit requirements, board layout constraints, and cost targets. This capacitor would commonly appear in power supply filtering circuits, signal coupling and blocking applications, noise suppression, and timing circuits across industrial control equipment, power electronics, communication devices, and consumer products. When evaluating alternatives, engineers consider factors such as temperature stability characteristics, equivalent series resistance, voltage derating curves, and proven field reliability in similar applications. For complete technical specifications and performance characteristics, manufacturers' datasheets provide detailed electrical parameters, temperature coefficients, and derating information essential for precise circuit design and reliability analysis.
