CL05C3R9CB5NNNC

The CL05C3R9CB5NNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for general-purpose decoupling, coupling, and filtering applications in electronic circuits. This component belongs to Samsung's CL05 series, which represents a compact 0402 (metric 1005) surface-mount package format—one of the most widely used capacitor sizes in modern consumer electronics, industrial control systems, and telecommunications equipment. Multilayer ceramic capacitors are fundamental passive components used to store electrical energy and manage signal integrity in countless applications. The CL05 series specifically targets high-volume production environments where space constraints and cost efficiency are critical design considerations. These capacitors are typically employed for power supply decoupling near integrated circuits, EMI/RFI filtering, AC coupling in signal paths, and general energy storage in compact assemblies. The 0402 package size makes this part ideal for densely populated circuit boards where miniaturization is essential. Engineers commonly specify components from Samsung's CL05 line when designing compact consumer devices, portable instrumentation, automotive electronics, and industrial IoT solutions. The small footprint allows designers to maximize PCB real estate while maintaining adequate capacitive functionality throughout their designs. Samsung's CL05 series is manufactured using advanced multilayer ceramic technology, delivering reliable performance across extended operating temperature ranges suitable for most industrial applications. These capacitors exhibit low equivalent series resistance (ESR) and equivalent series inductance (ESL), making them particularly effective for high-frequency decoupling tasks where rapid transient response is necessary. An engineer might select this specific part number over alternatives for several reasons. First, Samsung MLCCs from the CL05 series benefit from established supply chains and consistent manufacturing quality, reducing procurement risk in high-volume productions. Second, the 0402 package represents an optimal balance between component size and handling practicality—larger than 0201 packages (which present assembly challenges) yet significantly more compact than 0603 alternatives. Third, this particular series offers broad compatibility with standard PCB assembly equipment and reflow profiles used throughout the electronics manufacturing industry. The component's suitability extends across military-grade to commercial applications, depending on specific circuit requirements and environmental conditions. Electronics designers evaluating passive component selections will find the CL05 series attractive for applications demanding proven reliability, cost-effectiveness, and space-saving benefits without sacrificing performance standards.
