CL21A106KQQN3NE

The CL21A106KQQN3NE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable passive component widely used across industrial electronics, consumer devices, and embedded systems. This component belongs to Samsung's established capacitor portfolio, engineered to deliver consistent performance in demanding applications where compact size and electrical stability are essential requirements. As a ceramic capacitor, this component stores and releases electrical charge, functioning as a filter, bypass element, or coupling device in circuit designs. MLCCs like this part are fundamental building blocks in power supply circuits, signal conditioning stages, and noise suppression applications. Engineers integrate these capacitors into PCB layouts to stabilize voltage rails, filter high-frequency noise, and decouple power distribution networks from integrated circuits and other active components. The CL21A106KQQN3NE features a surface-mount package configuration, making it suitable for automated assembly processes and high-density PCB designs typical of modern industrial and commercial electronics. Its compact form factor allows engineers to optimize board real estate while maintaining the electrical performance needed for contemporary applications. The part designation indicates it belongs to Samsung's widely-adopted CL21 series, known for consistent quality and availability across global supply chains. This capacitor type is commonly specified in applications including industrial automation equipment, power management modules, telecommunications infrastructure, LED drivers and lighting systems, motor control circuits, and general-purpose consumer electronics. The ceramic material composition provides good frequency response characteristics and stable behavior across a range of operating conditions, making it suitable for both DC filtering and AC coupling applications. Engineers often select Samsung MLCCs like the CL21A106KQQN3NE when they require a proven component with reliable performance history, established manufacturing standards, and consistent availability. Samsung's quality control processes and widespread adoption of this series across OEM production lines mean that designers can confidently specify this part with expectations of consistent electrical characteristics and long-term supply continuity. The part's presence in established design ecosystems also reduces qualification risk for system integrators and manufacturers. For design engineers working on industrial equipment, control systems, or consumer products requiring robust passive components, the CL21A106KQQN3NE represents a standard-grade solution offering the balance of performance, reliability, and cost-effectiveness that industrial buyers expect. When integrated into properly designed circuits with appropriate derating practices, this capacitor provides durable operation across typical industrial temperature and environmental conditions.
