CL21A105KOFNNNF

# CL21A105KOFNNNF - Samsung Multilayer Ceramic Capacitor The CL21A105KOFNNNF is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a widely-used component in modern electronics. This capacitor belongs to Samsung's CL21 series, which comprises general-purpose ceramic capacitors designed for applications requiring compact size, reliable performance, and cost-effectiveness across consumer and industrial product categories. Multilayer ceramic capacitors function as passive components that store and release electrical energy within a circuit. They are essential building blocks in power distribution networks, signal coupling, decoupling, and filtering applications. The CL21 series specifically targets mainstream applications where moderate voltage ratings and standard performance characteristics are sufficient, making these capacitors popular in both prototype development and high-volume manufacturing environments. The "A" in the part number designation indicates this capacitor belongs to a performance class suited for general-purpose usage rather than specialized applications. Engineers typically select components from this series for non-critical timing circuits, power supply bypassing, audio signal path applications, and general noise suppression throughout PCB designs. The compact package size enables high component density on modern circuit boards while maintaining adequate electrical performance for standard operating conditions. This part number format follows industry-standard conventions for identifying specific electrical and mechanical characteristics. The combination of materials, construction methods, and terminal configuration results in a component with defined performance boundaries that remain stable across typical industrial operating environments. Engineers working with consumer electronics, industrial control systems, telecommunications equipment, and automotive applications frequently encounter these capacitors in reference designs and existing product platforms. Designers choose the CL21A105KOFNNNF variant specifically when existing designs call for this exact configuration, when PCB layouts have been optimized around this component's dimensions, or when supply chain standardization requires consistency with proven component selections. The Samsung manufacturer designation provides assurance of quality control and consistent performance across production batches, which is critical for manufacturers managing multiple production runs or requiring component traceability. The MLCC technology used in this part offers inherent advantages over older capacitor technologies, including excellent volumetric efficiency, low equivalent series resistance suitable for modern switching frequencies, and reliable performance across temperature variations encountered in typical industrial settings. These characteristics have made ceramic multilayer capacitors the industry standard for contemporary electronics manufacturing. This component integrates readily into standard assembly processes and works seamlessly with automated placement equipment used in modern manufacturing facilities. Its established presence in the component supply chain and compatibility with existing manufacturing infrastructure make it a practical choice for ongoing production and design updates.
