CL21A226MAQNNWE

The CL21A226MAQNNWE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, belonging to the CL21 series family. This component represents a practical choice for engineers designing electronic circuits requiring reliable capacitance storage in a compact form factor. Multilayer ceramic capacitors are fundamental passive components used across virtually every modern electronic device. The CL21 series from Samsung is engineered for general-purpose applications where cost-effectiveness, miniaturization, and stable performance are essential. These capacitors are constructed from multiple layers of ceramic dielectric material with alternating metal electrodes, allowing manufacturers to achieve significant capacitance values in small physical packages. The CL21A designation indicates this capacitor uses an X7R dielectric material, which provides relatively stable capacitance across a wide temperature range compared to other ceramic dielectric types. This stability makes X7R capacitors particularly suitable for applications where temperature variations could otherwise degrade circuit performance. The "226" portion of the part number is the capacitance code, indicating the component's rated capacitance value. Applications for capacitors like the CL21A226MAQNNWE span diverse industrial and consumer electronics sectors. These components commonly appear in power supply circuits, signal coupling and decoupling applications, timing circuits, filtering stages, and general-purpose energy storage roles within larger assemblies. Automotive electronics, telecommunications equipment, industrial control systems, and consumer appliances all rely on MLCCs for proper operation. The CL21 package is a surface-mount technology (SMT) component, meaning it is designed for automated placement on printed circuit boards during manufacturing. This facilitates high-volume production and reduces assembly costs compared to through-hole alternatives. The compact package size also enables space-constrained designs where board real estate is premium. Engineers typically specify Samsung's CL21 series MLCCs when seeking a balance between performance, reliability, and economics. Samsung's manufacturing processes and quality controls have established these capacitors as dependable components for applications that do not require exotic materials or extreme performance metrics. The X7R dielectric provides adequate stability for most mainstream applications without the premium cost associated with more specialized dielectric formulations. For circuit designers selecting between competing capacitor options, the CL21A226MAQNNWE offers proven reliability within Samsung's established product family, compatibility with standard SMT assembly processes, and predictable electrical characteristics suited to general industrial and commercial applications. Designers can confidently integrate this capacitor into diverse circuits where stable, consistent performance across operational temperature ranges is required.
