CL05B331KB5NCNC

The CL05B331KB5NCNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for use in modern electronic circuits where compact size and reliable performance are essential. This component belongs to Samsung's established CL05 series, which serves as a workhorse in consumer electronics, industrial equipment, and telecommunications applications. Multilayer ceramic capacitors are fundamental passive components used to store electrical charge, filter signals, couple or decouple AC and DC signals, and stabilize power supply circuits. The CL05 series specifically targets applications requiring small form factors without compromising performance. These capacitors are constructed from multiple layers of ceramic dielectric material with internal metallic electrodes, resulting in a robust component capable of withstanding manufacturing processes and field deployment. The "05" designation in the part number indicates a 0402 metric case size (0.4mm × 0.2mm), making this an ultra-miniature component ideal for space-constrained applications. This package size is standard in modern printed circuit board design, allowing engineers to achieve high component density in compact devices. Despite their diminutive size, capacitors in this series deliver reliable performance across a broad range of applications. The "B" in the designation typically refers to the capacitor's dielectric class, affecting its temperature stability and voltage characteristics. The "331" code indicates the capacitance value within Samsung's standard capacitance matrix. This particular configuration makes the CL05B331KB5NCNC suitable for general-purpose filtering, decoupling, and bypass applications found in microcontroller circuits, power management modules, and signal conditioning stages. Engineers specify this exact part number when they need a proven, widely-available MLCC that offers consistent electrical performance and reliable solderability. Samsung's CL05 series maintains strict manufacturing standards ensuring compatibility with automated assembly processes and lead-free soldering requirements. The part's established presence in the industry means design teams can confidently source replacements and maintain long-term supply stability. Common applications include power supply decoupling near integrated circuits, high-frequency filtering in RF circuits, timing circuit stabilization, and general circuit noise suppression. The combination of miniature size, established reliability track record, and cost-effectiveness makes the CL05B331KB5NCNC a preferred choice for original equipment manufacturers developing consumer electronics, industrial controllers, and telecommunications equipment. For engineers designing space-critical circuits requiring dependable passive components, this Samsung MLCC delivers proven performance with the added benefit of widespread availability and consistent manufacturing quality.
