CL21B104KBCNNNC

The CL21B104KBCNNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung. This component belongs to the CL21 series, which represents Samsung's general-purpose ceramic capacitor line designed for broad industrial and commercial applications. Multilayer ceramic capacitors are among the most widely used passive components in modern electronics. They function as energy storage and filtering elements in circuits, smoothing voltage fluctuations, decoupling noise from power supplies, and enabling signal coupling and blocking across frequency ranges. The compact size and reliable performance of ceramic capacitors make them essential in virtually every category of electronic equipment. The CL21 series specifically targets applications requiring standard performance characteristics at a competitive cost point. These capacitors use a ceramic dielectric material stacked in multiple layers to achieve useful capacitance values in a small physical footprint. The series is suited for general industrial electronics, consumer appliances, lighting, power supplies, audio equipment, and automotive applications where demanding high-reliability specifications are not the primary requirement. The construction and materials of the CL21 line provide stable performance across normal operating temperature ranges typical of industrial environments. These capacitors exhibit the predictable behavior expected of X7R or similar temperature-compensated ceramic dielectrics, maintaining relatively stable capacitance values despite temperature variations during normal operation. Engineers typically specify components from the CL21 series when the application requirements call for a cost-effective, readily available capacitor without demanding the premium performance or specialized characteristics found in higher-grade alternatives. The series offers good availability and established supply chains across multiple distributors, reducing procurement risk for manufacturers building products at volume. The specific part number CL21B104KBCNNNC identifies a particular capacitance value and voltage rating within this family. The alphanumeric designation follows Samsung's standard coding scheme, where each segment of the part number indicates specific physical and electrical characteristics. This level of precision in part numbering ensures engineers can reliably source exact replacement components or specify particular values for circuit designs. The CL21 series remains popular for engineers designing cost-sensitive products where component reliability must be maintained without incurring premium costs associated with specialty capacitor lines. Whether used in filter networks, timing circuits, or bypass applications, these capacitors provide the foundational passive component performance required across diverse industrial and commercial electronics platforms.
