CL31C181JGFNFNE

The CL31C181JGFNFNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, belonging to the CL series of general-purpose film and ceramic capacitor products. This component is designed for use in a wide range of electronic circuits requiring stable capacitance and reliable performance across various operating conditions. Multilayer ceramic capacitors like this model are fundamental passive components used extensively in consumer electronics, industrial control systems, telecommunications equipment, and power management applications. They function to store electrical energy, filter signals, couple or decouple circuits, and stabilize voltage supplies. Engineers specify MLCCs in countless applications including power supplies, audio systems, RF circuits, and digital logic boards where compact size and cost-effectiveness are priorities. The CL31 designation indicates this capacitor belongs to Samsung's compact surface-mount package family, designed for automated assembly on printed circuit boards. The surface-mount form factor makes it ideal for space-constrained applications and high-volume manufacturing environments where pick-and-place equipment is standard. The "C" prefix denotes its ceramic dielectric material, which provides good stability and performance characteristics across temperature ranges typical in industrial and consumer applications. The "181J" portion of the part number encodes the capacitor's value and tolerance specifications according to standard electronic component naming conventions. The "G" and subsequent characters indicate the specific voltage rating, packaging variant, and manufacturing specifications relevant to Samsung's product classification system. Engineers select this specific part number when they require a reliable, compact ceramic capacitor with Samsung's quality standards and manufacturing consistency. The CL series is widely used because it offers predictable electrical behavior, suitable dielectric characteristics for general-purpose applications, and compatibility with standard PCB assembly processes. These capacitors maintain relatively stable capacitance across a practical temperature range, making them suitable for both consumer and industrial environments. The multilayer construction provides multiple dielectric layers in a single compact package, delivering higher capacitance values than older single-layer designs while maintaining a small footprint. This efficiency makes Samsung's CL series popular among design engineers optimizing for board space and component cost. When specifying this part, engineers benefit from Samsung's reputation for consistent quality control and wide availability through distribution channels. The standardized package and electrical characteristics ensure compatibility with existing designs and ease of substitution if needed, while the established manufacturing history makes long-term availability more predictable than with newer or specialized component families.
