CL21A475KACLRNC

The CL21A475KACLRNC is a ceramic film capacitor manufactured by Samsung, representing a practical component widely used in industrial electronics, power conversion, and signal conditioning applications. This part belongs to Samsung's established CL series, which is recognized for delivering reliable performance in demanding environments where compact packaging and cost efficiency are important considerations. Ceramic capacitors of this type function as energy storage and filtering components in electrical circuits. They are commonly specified in power supplies, switching converters, audio equipment, telecommunications infrastructure, and consumer electronics where space constraints require miniaturized solutions. Engineers select ceramic capacitors for applications requiring stable capacitance across operating conditions, low equivalent series resistance, and dependable performance over extended product lifespans. The "A" designation within the part number indicates this capacitor is rated for standard industrial voltage classes, making it suitable for a broad range of standard electronic circuits. The "CL21" prefix identifies it as part of Samsung's established cylindrical film capacitor family, which has been widely adopted across manufacturing sectors due to consistent quality and proven reliability in field applications. Components in this series are designed to withstand typical industrial environmental stresses, including thermal cycling and mechanical vibration common to factory automation, control systems, and embedded electronics. The radial lead configuration (indicated by the part number structure) allows straightforward through-hole mounting on printed circuit boards, making integration straightforward for engineers working with conventional PCB assembly processes. This contrasts with surface-mount alternatives and appeals to applications where compatibility with existing manufacturing infrastructure is important or where maintenance technicians need accessible component replacement. Engineers typically specify this exact part number when they require a proven, established component with consistent supply chains and well-documented long-term field performance. The Samsung CL series has accumulated substantial operational history across industrial applications, which engineers value when designing products requiring high reliability and minimal field failures. For applications where cost must be balanced against performance requirements, this capacitor offers a rational middle ground between premium specialty components and the most basic commodity options. The component's general characteristics make it particularly valuable in applications where environmental stability, proven track record, and integration simplicity outweigh the need for cutting-edge performance metrics. Industrial buyers and design engineers frequently return to established parts like this one across multiple product generations, recognizing the reduced risk and streamlined procurement associated with components with proven field performance.
