CL21A475KAQNNNG

# Product Description: CL21A475KAQNNNG The CL21A475KAQNNNG is a multilayer ceramic capacitor manufactured by Samsung, representing a practical component choice for a wide range of industrial and consumer electronics applications. This capacitor belongs to the CL21 series, which is specifically designed for general-purpose filtering, decoupling, and signal coupling functions in compact form factors. As a multilayer ceramic capacitor, this component utilizes alternating layers of ceramic dielectric material and metal electrodes to achieve stable capacitance in a small physical package. The CL21 series is characterized by its compact size relative to its capacitance rating, making it well-suited for space-constrained applications where board real estate is at a premium. These capacitors are commonly found in consumer electronics, telecommunications equipment, industrial control systems, and automotive electronics where reliability and cost-effectiveness matter. The part designation indicates this is a capacitor optimized for standard industrial operating conditions. Samsung's CL21 series capacitors are known for consistent performance across temperature ranges typical of commercial and industrial use. The "A" designation in the part number suggests this particular variant is specified for mainstream applications rather than specialized high-reliability or extreme temperature requirements. Engineers typically specify this component for applications requiring stable capacitive performance without demanding extreme voltage or temperature ratings. Common uses include power supply decoupling on PCBs, EMI filtering in signal lines, timing circuit applications, and general bypassing applications. The ceramic dielectric material provides good frequency characteristics, making these capacitors suitable for both DC bias applications and AC signal filtering up to moderate frequencies. The CL21 form factor is a standard surface-mount package, enabling automated assembly on modern production lines and reducing assembly costs compared to through-hole alternatives. This makes the part particularly attractive for medium to high-volume manufacturing environments. When selecting this specific part number versus alternatives, engineers should consider that Samsung's CL21 series offers a well-established balance of performance, cost, and availability. The series has been widely adopted across industries, which means design documentation, application notes, and long-term supply stability are generally favorable. This part would be chosen over higher-specification alternatives when the application does not require extreme voltage ratings, specialized temperature performance, or unusually tight tolerance specifications, allowing for optimal cost performance in the design.
