CL21B102KB65PNC

The CL21B102KB65PNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable passive component widely used in industrial and commercial electronic applications. This capacitor belongs to Samsung's established CL series family, which is recognized for consistent performance across manufacturing and design consistency that engineering teams depend on for high-volume production environments. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, serving critical functions in power supply filtering, signal coupling and decoupling, noise suppression, and frequency tuning circuits. The CL21B series specifically is designed for general-purpose applications where stability, miniaturization, and cost-effectiveness are important considerations. These capacitors are commonly found in industrial control systems, consumer electronics, telecommunications equipment, automotive electronics, and various embedded systems. The part designation provides insight into its construction and intended use. The "CL21B" prefix indicates this is a surface-mount capacitor in the 0805 package size, one of the most widely used footprints in modern PCB design. This package size strikes a practical balance between handling ease during assembly, space efficiency on circuit boards, and electrical performance. The package dimensions make it suitable for both automated assembly processes and manual rework when necessary, which appeals to manufacturers with varied production capabilities. Samsung's CL21B series capacitors are engineered to deliver stable performance across typical industrial operating conditions. These components are suitable for applications requiring moderate voltage ratings and general-purpose filtering and coupling functions. Engineers often specify Samsung MLCCs when they need established, predictable component characteristics with broad supply availability and proven track records in field applications. The specific variant designation indicates particular electrical characteristics that make this part suitable for distinct application requirements. Engineers evaluating this component typically consider factors such as the required voltage class, capacitance value, tolerance band, and operating temperature range alongside their circuit design parameters. The CL21B family's consistency and wide adoption in reference designs make it a logical choice for design teams seeking components with well-documented performance and minimal supply chain uncertainty. For industrial buyers and design engineers, Samsung's CL series MLCCs represent a mainstream choice that balances performance requirements with practical manufacturing considerations. These capacitors have demonstrated reliability in demanding environments, making them suitable specifications for equipment designed for long operational life and consistent performance.
