CL05B222JB5NNNC

The CL05B222JB5NNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for use in a wide range of electronic applications requiring reliable energy storage and signal coupling. This component belongs to the popular CL series of chip capacitors, which are widely recognized across the electronics industry for consistent performance and availability. Multilayer ceramic capacitors like this unit are fundamental passive components used in nearly every type of modern electronics, from consumer devices to industrial control systems and telecommunications equipment. They function by storing electrical charge between conductive plates separated by ceramic dielectric material, enabling them to smooth voltage ripples, filter high-frequency noise, block DC while passing AC signals, and stabilize power distribution networks. The designation CL05B suggests this capacitor uses a 0402 metric package size (1.0mm × 0.5mm), making it one of the smaller surface-mount formats available. This compact form factor allows designers to achieve high component density on circuit boards, which is particularly valuable in space-constrained applications like mobile devices, portable instrumentation, and miniaturized industrial control modules. Despite the small physical size, MLCC technology allows manufacturers to achieve useful capacitance values in these tiny packages through advanced multilayer construction. The "B" indicator in the part number typically refers to the voltage class, while the "222J" designation encodes the nominal capacitance value and tolerance specification. Engineers routinely select MLCCs from Samsung's CL series because the product line offers excellent consistency, broad availability, and predictable electrical performance across temperature and frequency ranges. The extensive catalog provides multiple capacitance values, voltage ratings, and tolerance classes, allowing design flexibility without requiring multiple supplier relationships. This component would typically be found in bypass and decoupling applications protecting sensitive IC power pins, in coupling circuits between amplifier stages, in timing circuits, and in EMI filtering networks. Industrial applications particularly value Samsung MLCCs for their stability in temperature-variable environments, making them suitable for factory automation equipment, power supplies, measurement instrumentation, and process control systems. Engineers specify this exact part number when their circuit design calculations determine the need for this particular capacitance value and voltage rating in a 0402 package, when they require Samsung's proven quality record, or when standardizing on Samsung components across a product line for supply chain consistency. The CL series represents a baseline, proven technology offering excellent reliability at economical cost.
