CL21A106KAYNNNG

The CL21A106KAYNNNG is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for general-purpose energy storage and filtering applications in electronic circuits. This component belongs to the CL21 series, a family of compact film and ceramic capacitors widely used in industrial and consumer electronics for decades. Multilayer ceramic capacitors like this part are fundamental passive components used to smooth voltage ripple, filter high-frequency noise, decouple power supplies, and provide localized energy storage near integrated circuits and other active components. The CL21 series is particularly valued in applications where space efficiency, cost-effectiveness, and reliable long-term performance are required. These capacitors are commonly found in power management circuits, audio equipment, switching power supplies, telecommunications infrastructure, automotive electronics, and industrial control systems. The "A" designation in the part number indicates this capacitor uses a dielectric material formulated for stable capacitance across a moderate temperature range, making it suitable for general industrial applications rather than specialized high-temperature or high-reliability military contexts. Samsung's CL21 series capacitors are manufactured to consistent standards and are recognized for predictable electrical characteristics and good mechanical durability in production environments. This particular package type represents a conventional through-hole or surface-mount form factor that has proven reliable in both legacy and modern PCB assembly processes. The compact size of the CL21 series allows designers to integrate these components into dense circuit layouts without requiring excessive board space, which is important for applications where miniaturization and cost reduction are priorities. Engineers typically specify the CL21A106KAYNNNG when they need a dependable ceramic capacitor with proven field history, good availability from multiple sources, and compatibility with standard manufacturing processes. Compared to alternatives, this part offers a balance of performance, cost, and supply chain stability. The Samsung manufacturer designation provides assurance of consistent quality control and traceability, which is important for industrial applications requiring documentation and repeatability. The component is suitable for operating voltages and temperature ranges typical of mainstream industrial electronics. Its construction as a multilayer ceramic capacitor means it exhibits low equivalent series resistance and inductance, making it effective for high-frequency noise suppression and decoupling applications where performance stability matters. When sourcing passive components like this capacitor, engineers benefit from selecting established series from recognized manufacturers to ensure long-term availability, consistent performance, and reliable technical support throughout the product lifecycle.
