CL03B561KO3NNNC

The CL03B561KO3NNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, belonging to the CL03 series of compact film-type capacitors. This component is designed for general-purpose decoupling, filtering, and coupling applications in electronic circuits where space constraints and reliability are important considerations. Multilayer ceramic capacitors like this model are among the most widely used passive components in modern electronics. They consist of alternating layers of ceramic dielectric material and metal electrodes, which allows manufacturers to achieve relatively high capacitance values in extremely small packages. The CL03 series specifically targets applications requiring a balance between performance, miniaturization, and cost-effectiveness, making it suitable for consumer electronics, industrial control systems, telecommunications equipment, and automotive applications. The CL03B designation indicates this capacitor is part of Samsung's standard MLCC lineup, engineered to meet IEC and AEC standards depending on the intended application. These capacitors are commonly used in power supply circuits for voltage regulation, in signal processing circuits for AC coupling and filtering, and near integrated circuit pins for high-frequency noise suppression. The compact size of the CL03 package allows engineers to fit these components into densely populated circuit boards without sacrificing electrical performance. Engineers might specify the CL03B561KO3NNNC over alternative capacitor technologies or package sizes for several reasons. First, MLCCs offer excellent frequency response characteristics, making them ideal for high-speed digital and RF applications. Second, they provide stable performance across a wide temperature range, which is critical for industrial and automotive environments. Third, the specific package size allows for efficient use of PCB real estate, reducing overall assembly costs and board dimensions. Finally, Samsung's manufacturing consistency and quality control make this part suitable for mission-critical applications where component reliability directly impacts system performance. When sourcing this component, engineers should verify that the specific electrical characteristics—such as capacitance value, voltage rating, and temperature coefficient—match their circuit requirements. The part number structure includes indicators for these specifications, so careful cross-referencing with technical documentation ensures proper circuit function. As with all MLCCs, designers should also consider aging characteristics and voltage derating in their calculations to maintain reliable long-term operation. This component represents Samsung's commitment to providing dependable passive components for the global electronics manufacturing industry.
