CL21A106KQQNNNE

The CL21A106KQQNNNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for use in a wide range of electronic applications requiring stable capacitance and reliable performance. This component belongs to the CL21 series, which represents a mainstream offering in the capacitor market for general-purpose and industrial applications. Multilayer ceramic capacitors are fundamental passive components used to store electrical energy, filter signals, and stabilize voltage supplies across circuit boards. The CL21 series is widely recognized in the electronics industry for delivering consistent performance in mainstream applications where cost-effectiveness and reliability are equally important. These capacitors are commonly found in consumer electronics, industrial control systems, telecommunications equipment, and power supply circuits. The part number designation reveals key characteristics of this specific component. The "A" in the part number indicates the voltage and capacitance class, while the alphanumeric suffix provides information about the specific electrical characteristics and packaging configuration. Samsung's CL series capacitors are designed to meet industry standards and are compatible with standard PCB assembly processes, including both manual and automated placement equipment. One of the primary reasons engineers specify components from the CL21 series is their proven track record in high-volume manufacturing environments. These capacitors offer a balance between performance, cost, and availability that makes them ideal for applications where long-term reliability and supply chain stability are important considerations. The series is manufactured using mature production processes, which contributes to consistent quality and predictable behavior across manufacturing batches. The CL21A106KQQNNNE would typically be selected for applications including power distribution networks, signal coupling and decoupling circuits, filtering in switching power supplies, and general-purpose energy storage functions. Engineers often choose Samsung's CL series when designing products intended for high-volume production, as the widespread availability and standardization of these components can simplify sourcing and qualification processes. The ceramic dielectric material used in MLCCs provides good temperature stability across a range of operating conditions, making them suitable for both consumer and industrial temperature environments. The compact package size inherent to ceramic capacitors allows for high component density on modern circuit boards, which is increasingly important as electronic designs become more compact. For applications requiring a dependable, standard-performance multilayer ceramic capacitor with good availability and established qualification history, the CL21A106KQQNNNE represents a practical choice that balances performance requirements with practical manufacturing considerations.
