CL21B102KBCNNNC

The CL21B102KBCNNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a widely-used component in modern electronics where compact size and reliability are essential requirements. This capacitor belongs to Samsung's CL21 series, which is engineered for general-purpose applications across consumer, industrial, and automotive electronics. The "B" designation in the part number indicates the capacitor is designed for standard voltage applications. MLCCs in this series are constructed from multiple layers of ceramic dielectric material with interleaved metal electrodes, providing stable capacitance across a wide range of operating conditions. The compact 0805 package size makes the CL21B102KBCNNNC particularly suitable for modern PCB designs where space optimization is critical. This small form factor allows engineers to achieve higher component density while maintaining adequate performance margins. The "C" codes in the part number specification indicate this capacitor meets standard industry grade classifications for reliability and performance consistency, making it appropriate for both consumer and industrial-grade applications. Typical applications for capacitors of this type include decoupling and bypassing functions in digital circuits, where they filter high-frequency noise from power supply rails. Engineers frequently specify these capacitors in microcontroller circuits, digital signal processors, and mixed-signal applications. They are also commonly used in analog circuits for coupling and filtering applications, audio processing stages, and general-purpose filtering throughout consumer electronics, IoT devices, industrial control systems, and automotive electronics. The Samsung CL21 series is recognized in the industry for consistent performance and broad availability, making it a reliable choice for high-volume manufacturing environments. These capacitors offer stable behavior across temperature ranges typical of standard operating environments, and their construction method ensures minimal variations between units. Engineers might select the CL21B102KBCNNNC specifically when designing cost-sensitive applications requiring proven reliability, where the small footprint is advantageous for PCB routing and space constraints. The established manufacturing consistency of Samsung's CL21 series means predictable performance and easier supply chain management compared to lesser-known alternatives. Additionally, the widespread adoption of this series across the industry supports broader ecosystem compatibility and reduces qualification risk for new designs. For applications requiring extreme performance characteristics, temperature stability beyond standard ranges, or specialized voltage ratings, alternative capacitor types or series may be more appropriate. However, for mainstream electronics requiring dependable general-purpose capacitance in a compact package, this component represents a standard industry choice.
