CL31B105KCHSFNE

The CL31B105KCHSFNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung. This component belongs to the CL series family, which represents Samsung's standard-performance ceramic capacitor line widely used across consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors are fundamental passive components used for energy storage, filtering, decoupling, and signal coupling in electronic circuits. The CL31 package designates a 1206 surface-mount form factor, making it suitable for automated assembly on printed circuit boards. This size strikes a practical balance between compact board placement and handling ease during manufacturing. The "105K" portion of the part number indicates the component's nominal capacitance value of 1 microfarad (10 × 10^5 picofarads) with a K-tolerance rating, which is typical for general-purpose applications where moderate tolerance is acceptable. The "CH" designation refers to the voltage rating and dielectric material class within Samsung's naming convention, positioning this capacitor for standard industrial voltage applications rather than specialized high-voltage or low-voltage segments. Engineers commonly specify MLCCs in this capacitance range for bulk capacitance applications, input/output filtering on power supplies, decoupling of integrated circuits, and noise suppression on signal lines. The 1206 package size offers sufficient capacitance density for most mainstream applications while remaining cost-effective for high-volume production. The Samsung CL series represents a reliable, established platform with consistent availability and proven field performance across decades of deployment. Industrial and commercial equipment designers favor these capacitors for their stable electrical characteristics across operating conditions and their resistance to mechanical stress during manufacturing processes like wave soldering and thermal cycling. When selecting this specific part, engineers consider factors including the established reliability track record of the CL series, compatibility with standard 1206 land patterns, the capacitance value meeting circuit requirements, and the voltage rating providing adequate safety margin. Alternatives might include other manufacturers' offerings in similar package and value combinations, or different package sizes if board space or performance parameters differ. The CL31B105KCHSFNE represents a baseline choice for standard industrial applications where proven reliability and broad compatibility with existing design ecosystems are priorities. Its widespread use in equipment ranging from industrial control systems to consumer devices makes it a sensible specification for engineered products requiring long-term supply chain stability and manufacturing consistency.
