CL21a106KPFNNNE

The CL21a106KPFNNNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable passive component widely used in electronic circuits across industrial, consumer, and automotive applications. This capacitor is part of Samsung's established CL21 series, which is recognized for delivering consistent performance in mainstream electronic designs where compact packaging and cost-effectiveness are important considerations. Multilayer ceramic capacitors function as energy storage and filtering components in circuits. They are essential for decoupling, bypassing, and coupling applications where AC signals need to be passed while blocking DC components, or where power supply stabilization is required. The CL21 family represents a general-purpose grade of MLCC, suitable for non-critical filtering and stabilization roles throughout electronic equipment. The "a" designation in the part number indicates this capacitor belongs to a specific size and performance tier within the CL21 lineup. The component uses a standard ceramic dielectric material formulation typical of this series, which balances capacitance stability, frequency response, and cost. Engineers commonly specify MLCCs from this family in power supply circuits, audio signal paths, timing circuits, and general-purpose filtering applications where component footprint efficiency matters and precision capacitance tolerances are not critical requirements. Industrial and engineering buyers select capacitors like the CL21a106KPFNNNE when designing electronic control systems, automation equipment, and instrumentation where proven reliability and broad supplier availability are valued. The Samsung manufacture ensures consistent quality and longevity compared to some alternative sources, which can be important for equipment requiring extended service life or operating in demanding environments. Compared to alternatives in the MLCC market, the CL21 series offers a practical balance between performance, size, and cost. While more specialized ceramic capacitors exist for high-frequency, high-voltage, or ultra-low-ESR applications, the CL21 family serves as a workhorse component in mainstream electronics. Its established presence in the supply chain means design engineers can rely on consistent availability and well-documented compatibility with standard PCB assembly processes. The compact form factor of this component makes it ideal for modern circuit board designs where space constraints require efficient component placement. Its ceramic construction provides inherent reliability and resistance to mechanical stress during manufacturing and deployment. For engineers designing cost-conscious equipment with moderate performance requirements, the CL21a106KPFNNNE represents a proven, accessible solution backed by Samsung's manufacturing reputation and widespread industry adoption.
