CL21B102KCANFNC

The CL21B102KCANFNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable passive component widely used in electronic circuit design and industrial applications. This capacitor belongs to the CL21 series, which is engineered for general-purpose filtering, decoupling, and energy storage functions across a broad range of consumer and industrial electronics. Multilayer ceramic capacitors like this component are fundamental building blocks in modern circuit design. They function by storing electrical energy in an electric field between multiple ceramic layers and metallic electrodes, enabling rapid charge and discharge cycles. These capacitors are essential for power supply decoupling, noise filtering, timing circuits, and signal coupling applications where compact, cost-effective solutions are required. The CL21 series is commonly encountered in industrial control systems, power management circuits, telecommunications equipment, automotive electronics, and consumer appliances. Engineers specify these capacitors in applications requiring stable performance across operating temperature ranges while maintaining compact physical dimensions. The series is designed to offer good capacitance stability and reliable performance in high-volume manufacturing environments. The part designation CL21B102KCANFNC indicates specific characteristics within Samsung's standardized naming convention. The "CL21" prefix identifies the series and package type, which is a radial-leaded through-hole format suitable for traditional PCB assembly methods. The mid-section codes define the capacitance value and voltage rating, while the suffix identifies the dielectric material, tolerance class, and specific manufacturing variant. This particular configuration makes it suitable for engineers working with established circuit designs or legacy systems where through-hole components are preferred or required. Samsung's CL21 series capacitors are manufactured to stringent quality standards and are widely recognized in industrial electronics for consistent performance and availability. The through-hole package style provides mechanical robustness and is particularly valued in applications where component vibration resistance and ease of manual rework are important considerations. When selecting this specific part, engineers typically do so because they require a Samsung MLCC in this particular package and performance class, need to maintain compatibility with existing designs, or have qualified this exact part number through their reliability and quality assurance processes. The CL21B102KCANFNC remains a standard offering for applications where proven, stable capacitor performance and established supplier relationships matter more than the latest miniaturized technology.
