CL05B393KO5NNNC

The CL05B393KO5NNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable component choice for a broad spectrum of industrial and consumer electronics applications. This capacitor belongs to Samsung's established line of general-purpose ceramic capacitors designed to meet demanding performance requirements in modern electronic designs. Multilayer ceramic capacitors are fundamental passive components used to store electrical energy, filter signals, and stabilize power supplies across virtually every category of electronic equipment. The CL05B series designation indicates this is a 0402-inch (metric 1005) package size—one of the most widely adopted compact form factors in contemporary circuit design. This miniature footprint makes it ideal for space-constrained applications where engineers need to maximize circuit density without sacrificing performance or reliability. The specific designation within Samsung's catalog suggests this part is engineered for applications requiring stable capacitance across operational temperature ranges typical of industrial equipment. Ceramic capacitors in this class are commonly specified in analog and digital circuits for bypass and decoupling functions, where they suppress high-frequency noise and stabilize voltage rails near integrated circuits. They also serve roles in timing circuits, filtering stages, and energy storage applications where moderate capacitance values are needed. Engineers frequently select Samsung's CL05B series capacitors because of their consistent electrical characteristics, proven reliability track record, and ready availability through established distribution channels. Samsung maintains rigorous quality standards across its ceramic capacitor manufacturing, providing designers with confidence in part performance and longevity. For designers working on products requiring high-volume production runs, the established manufacturing ecosystem and broad market acceptance of this series reduces design risk and qualification time. The 0402 package size represents an optimal balance for many applications—small enough to enable modern PCB designs and automated assembly processes, yet large enough to provide adequate capacitance and voltage handling capability without requiring specialized handling equipment. This package density is standard across the electronics industry, meaning design tools, assembly processes, and inventory management systems are well-established. Industries routinely specifying components from Samsung's ceramic capacitor lineup include telecommunications, automotive electronics, industrial control systems, power management applications, and consumer electronics. The combination of compact size, proven performance, and broad compatibility makes this part a practical default choice for engineers developing new products or maintaining existing designs. For engineers evaluating this component, compatibility with existing supply chains, proven field performance data, and the ability to source replacements with consistent specifications represent key advantages of selecting established manufacturers like Samsung for fundamental passive components.
