CL21B104KBCNNN

The CL21B104KBCNNN is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable passive component widely used across industrial electronics, consumer devices, and embedded systems applications. This component belongs to the CL series family, which is recognized for consistent performance and broad availability in the global supply chain. Multilayer ceramic capacitors like this part serve as essential energy storage and filtering elements in electronic circuits. They are used to smooth voltage ripples, decouple power supplies, block DC signals while passing AC signals, and filter high-frequency noise in power distribution networks. The versatility of ceramic capacitors makes them indispensable in virtually every category of modern electronics, from simple discrete circuits to complex industrial control systems. The CL21B designation indicates this capacitor uses a specific dielectric formulation and physical package configuration optimized for general-purpose applications. The part's construction utilizes multiple ceramic layers with interleaved electrodes, allowing manufacturers to achieve relatively high capacitance values in a compact footprint. This design approach provides excellent volumetric efficiency, making it ideal for space-constrained applications where board real estate is premium. Samsung's CL series capacitors are commonly specified in applications requiring stable performance across typical operating conditions. Engineers select these components for their predictable electrical characteristics, consistent manufacturing quality, and compatibility with standard automated assembly processes. The ceramic composition used in this series offers reliable behavior across temperature ranges typical for industrial and commercial-grade equipment. The part number structure indicates specific electrical parameters and packaging details embedded within the designation. The "104" portion of the part number carries particular significance for capacitor identification and is used by design engineers during component selection and bill-of-materials preparation. The "B" designation relates to the voltage rating class, while the "KBCNNN" suffix identifies the specific variant, packaging format, and any special manufacturing options. Engineers may choose this specific part number over alternatives based on several factors: compatibility with existing designs, proven field reliability in their application environment, availability from multiple supply channels, and established relationships with Samsung as a manufacturer. In industrial applications particularly, component standardization reduces qualification costs and supply chain risk. The CL21B104KBCNNN represents a mature, well-established product within Samsung's extensive capacitor portfolio. Its continued availability and widespread use across industries reflects both the component's solid engineering fundamentals and its suitability for the broad range of applications where ceramic capacitor technology is the appropriate technical solution.
