CL21A106MPFNNNE

The CL21A106MPFNNNE is a multilayer ceramic capacitor manufactured by Samsung, part of the CL21 series designed for general-purpose industrial and consumer electronics applications. This component falls into the class of film and ceramic capacitors commonly used in power supply circuits, filtering applications, and signal coupling throughout modern electronic equipment. Multilayer ceramic capacitors like this model are constructed from alternating layers of ceramic dielectric material and metal electrodes, stacked and fired together to create a compact, reliable energy storage device. The CL21 series represents Samsung's established line of capacitors engineered to provide stable performance across a wide range of operating conditions typical in industrial environments. The specific construction and material composition of this part make it suitable for applications requiring moderate capacitance values with reasonable voltage ratings. Engineers frequently specify capacitors from this series in audio equipment, telecommunications hardware, industrial control systems, and general-purpose PCB designs where cost-effectiveness and proven reliability matter. The compact package size helps minimize board space while delivering consistent electrical performance. One key reason engineers select the CL21 series is the balance between performance characteristics and production-volume economics. These capacitors are widely available through distribution channels, have established manufacturing processes, and benefit from extensive field history across multiple industries. When engineers need a proven, standard-grade ceramic capacitor that doesn't require exotic materials or specialized performance attributes, the CL21 line offers a practical choice with predictable behavior. The multilayer construction provides advantages including high capacitance density relative to component size, which is important in space-constrained designs. Samsung's manufacturing processes ensure consistent performance across production batches, reducing design risk in applications where capacitor stability directly affects circuit performance. Common use cases include bypass and decoupling applications in power distribution networks, output filtering in switched-mode power supplies, timing circuits, and general energy storage where the application environment remains within standard industrial temperature and humidity ranges. The CL21 series has been employed in telecommunications infrastructure, consumer electronics, and industrial automation equipment for decades. When evaluating alternatives, engineers should consider that ceramic capacitors in this class offer distinct tradeoffs compared to other technologies. They provide better frequency response characteristics than larger electrolytic capacitors but may have different capacitance stability versus temperature compared to film-based alternatives. The CL21 remains a sensible specification when those tradeoffs align with circuit requirements and cost targets.
