GRM155B11C393KA01D

The GRM155B11C393KA01D 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. This particular component features a 0402 package size (also known as 1005 metric), making it one of the smallest standard surface-mount capacitor formats. The compact footprint is ideal for space-constrained designs where board real estate is at a premium, such as mobile devices, portable instruments, and densely populated circuit boards. Despite its diminutive size, the 0402 package offers reliable soldering and handling characteristics suitable for automated assembly processes. Multilayer ceramic capacitors like this model serve as essential building blocks in modern electronics. They function as energy storage elements, noise filters, and signal coupling/decoupling components in a wide range of circuits. Common applications include power supply filtering, high-frequency decoupling near integrated circuits, AC signal coupling, and resonant circuit tuning. The GRM155B11C series is particularly suited for mainstream industrial and commercial applications where cost-effectiveness and reliable performance are balanced against extreme environmental or frequency requirements. The "C" designation in this part number indicates the voltage rating class appropriate for general-purpose applications across consumer and industrial segments. Murata's GRM series utilizes advanced multilayer ceramic dielectric materials that provide stable capacitance across typical operating temperature ranges, making these capacitors dependable choices for applications that must function reliably in varied environmental conditions. Engineers typically specify this exact part number when they need a proven, established component with consistent supply chains and well-documented manufacturing history. The Murata GRM family is supported by extensive technical documentation and design resources, reducing integration risk in new products. Additionally, the widespread adoption of this series means that design teams can leverage proven circuit design practices and readily available application notes from Murata and the broader engineering community. For applications requiring surface-mount construction, compact packaging, and straightforward performance characteristics without specialized environmental ratings or extreme frequency operation, the GRM155B11C393KA01D represents a reliable and cost-effective capacitor solution. Its prevalence in production electronics makes it a practical choice for both new designs and replacement/repair applications where compatibility with existing boards is important.
