CL05C221JB5NNNC

The CL05C221JB5NNNC is a multilayer ceramic chip capacitor manufactured by Samsung. This component belongs to the general-purpose capacitor category and is designed for use in a wide range of industrial, consumer, and commercial electronic applications where stable capacitance and reliable performance are essential. Multilayer ceramic capacitors (MLCCs) like this part are fundamental passive components used in virtually every modern electronic circuit. They function to store electrical energy, filter signals, smooth power supply outputs, block DC while passing AC signals, and suppress electromagnetic interference. The compact size and low cost of chip capacitors make them ideal for high-volume manufacturing and space-constrained PCB designs. The CL05 designation indicates this capacitor uses a 0402 case size, one of the most common surface-mount package formats in modern electronics. This miniature footprint allows engineers to achieve high component density on circuit boards while maintaining manufacturability with standard pick-and-place equipment. Despite its small physical size, the 0402 package offers reasonable capacitance values and performance suitable for many applications. Samsung's CL05 series capacitors are found in consumer electronics, telecommunications equipment, automotive systems, industrial control circuits, power management modules, and portable devices. Their reliability and consistent performance make them a popular choice for original equipment manufacturers across multiple industries. The "C" in the part number indicates a ceramic dielectric material, which is standard for general-purpose applications. Ceramic capacitors offer good temperature stability, excellent frequency response, and are cost-effective for mainstream applications. Engineers typically specify ceramic chip capacitors when the circuit requirements allow for the normal characteristics associated with this dielectric type, including moderate tolerance ranges and temperature coefficients. When selecting the CL05C221JB5NNNC specifically, engineers are choosing a Samsung-branded component with established quality standards and consistent availability. The specific variant encoded in this part number—determined by the suffix codes—targets particular performance characteristics within the 0402 ceramic capacitor family. This makes it suitable for engineers who need predictable behavior in filtering, coupling, decoupling, or energy storage roles within their designs. The use of multilayer ceramic construction in this component provides stable capacitance across operating conditions and good performance in high-frequency applications. For engineers working on designs requiring proven component reliability from a recognized manufacturer in a standard package format, this part offers a practical solution that balances performance, cost, and availability.
