CL21A106KPCL3RC

The CL21A106KPCL3RC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for general-purpose filtering and coupling applications in electronic circuits. This component belongs to the CL21 series, which comprises conventional film-type MLCCs widely used across industrial and consumer electronics manufacturing. Multilayer ceramic capacitors like this model serve critical functions in power supply circuits, signal conditioning, noise filtering, and decoupling applications. Engineers specify MLCCs in situations where compact size, reliability, and cost-effectiveness are priorities. The CL21 series positioning makes this part suitable for mainstream industrial applications rather than specialized high-performance scenarios, making it a reliable choice for cost-sensitive designs that still demand reasonable performance standards. The component's construction uses multiple layers of ceramic dielectric material with alternating metal electrodes, a proven approach that delivers stable capacitance across typical operating conditions. Samsung's manufacturing quality ensures consistent performance characteristics across production batches, which is important for designers managing component procurement across multiple assembly runs or manufacturing facilities. This particular part number designation indicates a specific combination of capacitance value, voltage rating, tolerance, and packaging configuration within the CL21 family. The radial lead configuration typical of this series allows straightforward through-hole mounting on printed circuit boards, making it compatible with both legacy and current manufacturing processes. This backward compatibility makes the CL21 series attractive to companies maintaining older product lines alongside new designs. Engineers might select this exact part when circuit requirements align with its performance envelope and when benefiting from established supply chains and manufacturing familiarity. The CL21 series' long market presence means widespread design references, readily available supporting documentation, and predictable sourcing across multiple distributors globally. For applications where more specialized characteristics are unnecessary—such as ultra-low ESR, extreme temperature stability, or specialized voltage ratings—specifying a standard CL21 component reduces design complexity and procurement costs. Common application areas include consumer appliances, industrial control systems, LED lighting drivers, telecommunications equipment, and various computing peripherals. The robustness of this series across different environmental conditions supports use in both benign office environments and more demanding industrial settings with moderate temperature variations. For engineers evaluating this component, the key advantage lies in its balance of established reliability, widespread availability, reasonable cost structure, and compatibility with standard manufacturing processes. It represents a practical solution for circuit designers seeking proven performance without unnecessary premium specifications.
