CL05B221JB5NNNC

The CL05B221JB5NNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a compact solution for decoupling, filtering, and general-purpose energy storage applications in electronic circuits. This component belongs to the 0402 (metric 1005) package family, one of the most widely adopted sizes in modern electronics manufacturing due to its balance between miniaturization and practical handling characteristics. Multilayer ceramic capacitors like this model are fundamental building blocks in contemporary PCB design, particularly in space-constrained applications where component density is critical. The 0402 package format is extensively used across consumer electronics, telecommunications equipment, industrial control systems, medical devices, and automotive electronics. Engineers specify MLCCs in this size class for high-frequency decoupling near integrated circuits, noise suppression on power distribution networks, signal conditioning, and AC coupling applications. Samsung's CL05B series represents a reliable, mainstream offering in the capacitor market, characterized by consistent quality and wide industrial acceptance. Components in this series are designed for standard commercial and industrial operating environments, making them suitable for general-purpose applications that do not require specialized high-temperature or high-reliability variants. The specific designation within this part number indicates particular electrical and physical properties suited to common industrial requirements. Engineers often choose standardized MLCC offerings like the Samsung CL05B family when designing circuits that operate in typical temperature ranges and voltage conditions, as these parts offer cost-effectiveness without sacrificing reliability for mainstream applications. 0402 MLCCs continue to dominate the market despite advances in even smaller packages because they represent an optimal intersection of miniaturization, solderability, and mechanical robustness. The small footprint reduces PCB area consumption, which is particularly valuable in compact devices and high-density designs. Simultaneously, the 0402 size remains large enough to maintain good mechanical strength during assembly, rework, and handling operations. In practical design scenarios, engineers may evaluate this specific part against competing offerings based on factors such as dielectric type, voltage rating, capacitance value, temperature coefficient stability, and sourcing reliability. Samsung's broad distribution network and consistent manufacturing make their standard series components accessible for production quantities, supporting both prototype development and high-volume manufacturing. The CL05B221JB5NNNC serves applications requiring dependable capacitive performance in a universally compatible package format, making it a practical specification choice for engineers designing efficient, compact electronic systems across numerous industrial and commercial sectors.
