CL21A475KPFNNNF

The CL21A475KPFNNNF is a multilayer ceramic capacitor manufactured by Samsung, designed for a wide range of industrial and consumer electronic applications. This component belongs to the CL21 series, which represents Samsung's established line of general-purpose ceramic capacitors suitable for mainstream electronics manufacturing. Multilayer ceramic capacitors (MLCCs) like this part are fundamental passive components used to store and regulate electrical charge in circuits. They serve critical functions including power supply filtering, signal coupling and decoupling, noise suppression, and frequency compensation across numerous applications. The compact size and reliable performance of ceramic capacitors make them indispensable in modern electronics from power management boards to signal processing circuits. The CL21A designation indicates this capacitor uses a standard through-hole or surface-mount package configuration optimized for conventional PCB assembly. Samsung's CL21 series is widely specified in industrial control systems, telecommunications equipment, automotive electronics, consumer appliances, and general-purpose industrial boards where cost-effectiveness and proven reliability are priorities. These capacitors represent a middle-ground solution between ultra-compact and specialized high-performance alternatives, making them suitable for designs where standard performance characteristics meet application requirements without premium pricing. Engineers typically specify Samsung's CL21 series when designing boards that require dependable capacitive performance without specialized requirements such as extreme temperature operation, unusually high voltage ratings, or precision tolerance demands. The series benefits from Samsung's extensive manufacturing scale, meaning broad availability and consistent quality across production batches—important factors in industrial purchasing where supply chain predictability matters significantly. The component's designation code contains information about its electrical characteristics, including voltage class and capacitive value, though exact specifications should be verified against the relevant technical documentation. Designers appreciate this series for its balance of performance, package efficiency, and established track record in proven applications. Whether used in power delivery networks, analog filtering stages, or general circuit stabilization, these capacitors provide the foundational support that many industrial electronic designs require. When selecting capacitors for production designs, engineers evaluate factors including package footprint, voltage rating adequacy, capacitance value precision, temperature stability, and long-term reliability data. Samsung's CL21 series maintains a strong reputation in industrial markets, making it a straightforward specification for boards requiring conventional ceramic capacitor performance in standard operating environments. This part represents the type of fundamental component that forms the backbone of reliable industrial electronics manufacturing.
