CL31C120JBCNNNC

The CL31C120JBCNNNC is a ceramic capacitor manufactured by Samsung, designed for general-purpose filtering and coupling applications in electronic circuits. This component belongs to Samsung's CL series of multilayer ceramic capacitors (MLCCs), which are widely used across industrial, consumer electronics, and telecommunications equipment. Ceramic capacitors like this model serve critical functions in modern electronics, including AC coupling, DC blocking, power supply filtering, and noise suppression. The CL series is engineered to provide reliable performance in applications where compact size and cost-effectiveness are important considerations. These capacitors are commonly found in power management circuits, signal conditioning stages, and protection networks throughout industrial control systems, automotive electronics, and embedded devices. The part number structure indicates this is a surface-mount ceramic capacitor, typical of contemporary manufacturing standards. The specific designation reflects Samsung's comprehensive classification system, which encodes the component's electrical characteristics, package dimensions, and performance ratings into the part number itself. Like other components in this family, the CL31C120JBCNNNC is designed for soldering directly onto printed circuit boards using standard reflow processes, making it suitable for high-volume manufacturing environments. Engineers typically specify Samsung's CL series capacitors when they require dependable ceramic capacitor performance at competitive price points. These components are recognized for consistent quality, wide availability through distribution networks, and compatibility with standard PCB assembly procedures. The series encompasses various capacitance values and voltage ratings to accommodate different circuit requirements, from low-voltage digital logic applications to higher-voltage industrial power circuits. The ceramic dielectric material used in these capacitors provides stable electrical characteristics across operating temperature ranges typical for industrial and consumer applications. Samsung's manufacturing processes ensure repeatable performance and tight tolerances, which is particularly valuable in production environments where component consistency directly impacts yield rates and product reliability. For design engineers, the decision to specify the CL31C120JBCNNNC typically comes down to matching the specific capacitance value and voltage rating required for their circuit function, combined with Samsung's established reputation for quality and reliability in the ceramic capacitor market. These components represent a mainstream choice for standard filtering and coupling needs where premium performance characteristics or specialized features are not required, making them a practical solution for cost-sensitive applications requiring proven, dependable capacitor technology.
