CL21A475KBQNNNE

The CL21A475KBQNNNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for general-purpose filtering, decoupling, and energy storage applications across industrial and commercial electronic equipment. This component belongs to Samsung's established CL series of ceramic capacitors, which are widely recognized in the electronics industry for reliable performance in demanding environments. Multilayer ceramic capacitors like this unit are fundamental building blocks in modern electronics, used extensively in power supplies, audio equipment, telecommunications infrastructure, automotive systems, industrial control circuits, and consumer electronics. Engineers specify MLCCs in applications requiring compact size, high volumetric efficiency, and cost-effective solutions for energy storage and signal conditioning. The ceramic dielectric material provides excellent stability and low equivalent series resistance (ESR), making these capacitors particularly valuable in high-frequency filtering applications and decoupling networks where transient current demands must be rapidly managed. The CL21A designation indicates this capacitor uses a 1206 surface-mount package footprint, a standard size that provides an optimal balance between component density and ease of assembly on modern PCBs. This package format is compatible with automated pick-and-place equipment used in high-volume manufacturing environments, while remaining accessible for repair and prototyping work. The 1206 size also offers sufficient physical robustness for industrial applications subject to vibration, thermal cycling, and mechanical stress. Samsung's CL series capacitors are manufactured with consistent quality control processes and deliver predictable electrical performance across temperature and voltage operating ranges typical of industrial applications. These capacitors function reliably in standard commercial and industrial temperature environments, supporting the operational demands of equipment used in manufacturing facilities, process control systems, power distribution networks, and fixed installation equipment. Engineers select this specific part number when they require a proven, standardized solution that meets established design practices and qualification requirements. The widespread adoption of Samsung's CL series in industrial designs means extensive field history, simplified supply chain management, and compatibility with existing manufacturing processes and test procedures. For applications where component reliability, predictable sourcing, and integration with established PCB layouts are critical factors, this capacitor provides a trusted solution. Whether used as part of a larger filtering network, a decoupling element near integrated circuit power pins, or an energy storage component in timing circuits, the CL21A475KBQNNNE offers the electrical performance and mechanical reliability expected in professional electronic equipment.
