CL05C221JB51PNC

The CL05C221JB51PNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable component commonly used across industrial electronics, consumer devices, and telecommunications equipment. This capacitor belongs to Samsung's established MLCC product family and is designed to meet the performance requirements of modern compact electronic assemblies. Multilayer ceramic capacitors like this component serve as essential energy storage and filtering elements in virtually all electronic circuits. They are used for decoupling, noise filtering, coupling, and bypass applications. Engineers rely on these capacitors to stabilize power supply voltages, suppress electromagnetic interference, and maintain signal integrity in digital and analog circuits. The widespread adoption of MLCCs across industries stems from their small physical size, cost-effectiveness, and proven reliability in high-volume manufacturing environments. The "CL05" designation indicates this capacitor uses a 0402 metric package size, making it one of the smallest standard surface-mount capacitor formats available. This compact footprint is highly desirable in modern PCB designs where space is at a premium. The 0402 package allows design engineers to achieve higher component density while maintaining manufacturability and repairability. This size is standard across consumer electronics, IoT devices, automotive control modules, and industrial instrumentation where board real estate must be optimized. The "221J" marking provides information about the capacitor's rated value and tolerance class. This part is manufactured to standard industrial specifications typical of general-purpose MLCC applications. Samsung's manufacturing processes ensure consistent performance across production batches, which is critical for engineers designing systems that must function reliably across varying environmental conditions and electrical loads. The "51" suffix typically indicates specific manufacturing parameters or material composition within Samsung's internal classification system, often relating to the dielectric material used. Samsung produces MLCCs in various dielectric classes to serve different application requirements, from general-purpose to high-temperature or high-reliability variants. Engineers select this exact part number when their circuit design requires the specific electrical characteristics this capacitor provides, combined with the proven manufacturing quality and availability that Samsung brand components offer. In applications requiring certified component traceability, consistent supplier reliability, or compliance with specific purchasing standards, the CL05C221JB51PNC provides a well-established solution. This component is suitable for both commercial-grade applications and systems requiring higher reliability standards.
