CL21A475MPFNNNE

The CL21A475MPFNNNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable component choice for industrial and consumer electronics applications. This capacitor belongs to Samsung's established CL series family, which is widely recognized across the electronics industry for consistent performance and availability in high-volume manufacturing environments. Multilayer ceramic capacitors like this part are fundamental passive components used to store and release electrical energy within circuits. They serve critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and timing circuit stabilization. The compact form factor of this MLCC makes it ideal for modern printed circuit board designs where space efficiency is paramount. The part designation indicates this is a leaded or surface-mount variant within Samsung's CL21A series. Capacitors in this series are typically engineered for general-purpose industrial applications, consumer electronics, and equipment requiring stable, long-term performance across normal operating temperature ranges. The construction method and materials used in MLCCs like this one provide excellent reliability when exposed to thermal cycling, mechanical stress, and prolonged operation. Engineers frequently specify Samsung CL series capacitors in applications ranging from power management circuits and audio equipment to telecommunications infrastructure and industrial control systems. The consistency of Samsung's manufacturing processes makes these components predictable in production environments where batch-level performance tracking and supply chain stability are important considerations. When selecting between alternative capacitor options, design engineers consider factors such as voltage rating, capacitance value, tolerance class, temperature coefficient, equivalent series resistance (ESR), and physical package dimensions. The CL21A series from Samsung is often chosen where cost-effectiveness must be balanced with proven reliability, where the application environment is well-defined, and where the specific electrical and thermal characteristics of this series meet the circuit requirements. The multilayer construction inherent to this component type offers advantages including compact size, high volumetric efficiency, and relatively low parasitic inductance compared to some legacy capacitor technologies. These characteristics make MLCCs particularly suitable for modern high-frequency and switching circuit applications. For engineers evaluating this specific part number, compatibility with existing supply chains, manufacturing processes, and long-term availability through established distribution networks often influences the decision to standardize on Samsung CL series capacitors within product designs.
