CL31C221JDCNNNC

The CL31C221JDCNNNC is a ceramic capacitor manufactured by Samsung, designed for general-purpose applications in electronic circuits where reliable energy storage and filtering are required. This component belongs to the broad family of multilayer ceramic capacitors (MLCCs), which are among the most widely used passive components in modern electronics due to their compact size, cost-effectiveness, and stable performance across a wide range of conditions. Ceramic capacitors like this part are fundamental building blocks in countless industrial and consumer applications. They are commonly found in power supply circuits for filtering and decoupling, signal conditioning networks, timing circuits, and RF applications. In industrial equipment, they support stable operation of control boards, sensor interfaces, and power management systems. The ceramic dielectric material provides good electrical stability while maintaining a small physical footprint, making these capacitors ideal when board space is constrained and high component density is necessary. The designator "CL31" in the part number indicates this is a Samsung capacitor from a specific product line, while the "C221J" portion conveys information about the capacitance value and tolerance class. The "DCNNNC" suffix provides additional details about the component's packaging and specifications. Samsung's capacitor lines are engineered to meet strict quality standards required in both commercial and industrial settings, with consistent performance and reliable long-term operation. Designers and engineers specify this exact part number when they need a capacitor with the particular electrical characteristics encoded in the part number—including a specific capacitance value and tolerance—paired with Samsung's quality reputation and availability through established distribution channels. The ceramic construction offers advantages in terms of temperature stability, low equivalent series resistance (ESR) in many operating ranges, and minimal aging effects compared to some alternative dielectric materials. This component is suitable for use in temperature-controlled industrial environments as well as applications with moderate thermal cycling. Its compact package format allows integration into densely populated circuit boards common in modern equipment control systems, data acquisition platforms, and power electronics. Engineers selecting this part would typically be working on designs requiring precise capacitive performance without the bulk or cost associated with larger film or electrolytic alternatives, while needing the proven reliability associated with established ceramic capacitor manufacturers.
