CL05B103KB5NNND

The CL05B103KB5NNND is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for general-purpose filtering and decoupling applications in electronic circuits. This component belongs to Samsung's established CL series of ceramic capacitors, which are widely used across consumer electronics, industrial equipment, and telecommunications infrastructure. Multilayer ceramic capacitors like this part are fundamental passive components used to store electrical charge and filter noise in power supplies, signal conditioning circuits, and high-frequency applications. The "05" designation in the part number indicates this is a 0402 case size (imperial notation), representing one of the most compact standard surface-mount package options available. This small footprint makes it ideal for space-constrained PCB layouts where board real estate is at a premium, such as in portable devices, compact industrial controllers, and dense module designs. The alphanumeric suffix in this part number encodes important characteristics including the capacitor's dielectric material, voltage rating, and tolerance class. Samsung's CL series capacitors are typically available in X7R or X5R dielectric types, which provide stable capacitance across a wide operating temperature range—a critical requirement for applications where thermal stability matters. These dielectric formulations make the parts suitable for general-purpose decoupling near digital logic, microprocessors, memory modules, and analog circuits that may experience moderate temperature fluctuations. Engineers specify this particular part when they need a reliable, proven ceramic capacitor in a compact package with consistent electrical performance from a trusted manufacturer. Samsung MLCCs are recognized for quality control and long-term availability, making them attractive for both prototype development and high-volume production runs. The CL series represents a cost-effective solution that balances performance, package density, and procurement reliability. Typical applications include bypass filtering on power rails, AC coupling in amplifier circuits, and high-frequency noise suppression in digital systems. The 0402 package size particularly suits modern surface-mount assembly processes, reducing manufacturing complexity compared to larger through-hole alternatives while maintaining electrical performance adequate for mainstream industrial and commercial electronics. This component is RoHS compliant and lead-free, meeting current environmental and regulatory standards for electronics manufacturing. As a passive component with no active elements, it offers unlimited shelf life under proper storage conditions, making it suitable for both immediate production use and inventory management across various manufacturing environments.
