CL31B123JBCNNNC

The CL31B123JBCNNNC is a ceramic capacitor manufactured by Samsung, designed for general-purpose applications in electronic circuits. This component belongs to the CL31 series, a family of multilayer ceramic capacitors (MLCCs) widely used across consumer electronics, industrial equipment, and telecommunications infrastructure. Ceramic capacitors like this part are fundamental passive components that store electrical charge and are essential in circuit designs for filtering, decoupling, coupling, and noise suppression. The CL31 series represents a mid-range offering in Samsung's capacitor portfolio, suitable for cost-sensitive applications where reliability and consistent performance are required without premium specifications. Based on the part number structure, this capacitor features a surface-mount package format, making it ideal for automated PCB assembly processes common in modern manufacturing. The specific package size allows for high-density circuit board layouts while maintaining adequate spacing for thermal management and signal integrity. Engineers often select components from this series when designing power supply circuits, audio equipment, computing devices, and industrial control systems. The CL31 series is typically specified in applications where moderate voltage ratings and standard tolerance classes meet design requirements. Common use cases include bypass and decoupling applications near microprocessors and digital logic circuits, where this capacitor helps maintain stable voltage levels and reduces electromagnetic interference. The component is also suitable for coupling and filtering applications in analog signal processing circuits. One reason engineers choose the CL31 series over alternatives is the balance between performance, cost, and availability. Samsung's established manufacturing processes ensure consistent quality across production runs, which is critical for high-volume manufacturing and supply chain reliability. These capacitors meet standard industry specifications and certifications, making them suitable for applications requiring compliance with RoHS and other environmental standards. The construction of multilayer ceramic capacitors in this series provides stable capacitance across different operating conditions, though designers should account for standard MLCC characteristics such as capacitance variation with applied voltage and temperature. This makes the CL31 series particularly suitable for applications where minor capacitance shifts are acceptable or can be compensated for in circuit design. For engineers evaluating this specific part number, consideration of the exact capacitance value, voltage rating, and physical dimensions encoded in the part number is essential when cross-referencing design requirements. The CL31 series from Samsung offers a reliable, proven solution for standard industrial and consumer electronics applications where proven performance and cost-effectiveness are priorities.
