GRM31B7U3A561JW31L

The GRM31B7U3A561JW31L is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading suppliers of passive components for electronics. This capacitor is part of Murata's GRM series, which represents a broad family of surface-mount ceramic capacitors designed for high-reliability applications across consumer, industrial, and automotive sectors. Multilayer ceramic capacitors like this component serve as energy storage and filtering elements in electronic circuits. They are essential for decoupling, noise suppression, timing circuits, and signal conditioning across virtually all modern electronic equipment. The compact surface-mount package format allows for high-density circuit board layouts, making MLCCs ideal for space-constrained applications where traditional through-hole components are impractical. The GRM31 designation indicates this is a 1206 package size capacitor—a widely standardized surface-mount format measuring approximately 3.2mm by 1.6mm. This mid-range package size offers a practical balance between capacitance density and ease of handling and assembly. The 1206 format remains popular in industrial and professional-grade equipment where reliability and performance consistency are prioritized over maximum miniaturization. Murata's GRM series capacitors are specified for applications requiring stable performance across extended temperature ranges and demanding operational conditions. These components typically exhibit low equivalent series resistance (ESR) and are engineered to maintain consistent electrical characteristics under thermal cycling and long-term aging. Such properties make them suitable for power management circuits, RF filtering, LED drivers, telecommunications equipment, industrial control systems, and automotive electronics. Engineers select specific Murata GRM capacitors like the GRM31B7U3A561JW31L when the application demands a combination of proven reliability, consistent quality, and performance within defined operating parameters. The precise part number indicates particular electrical specifications—including capacitance value, voltage rating, and dielectric material composition—that match exact circuit requirements. Murata's manufacturing processes and quality standards ensure minimal variation between units, which is critical in applications where predictable component behavior directly impacts system performance and longevity. The GRM series has established a strong track record in industrial and professional applications over decades, making it a trusted reference standard for design engineers and procurement specialists. When specifications call for a capacitor with known performance characteristics and proven field reliability, this part number represents a solution with extensive validation across multiple industries and application environments.
