CL31C181JBNC

The CL31C181JBNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for use in a wide range of electronic applications requiring compact, reliable energy storage and filtering. This component belongs to Samsung's established line of general-purpose ceramic capacitors, which are widely deployed across consumer electronics, industrial equipment, telecommunications infrastructure, and automotive systems. Multilayer ceramic capacitors function as essential passive components in electronic circuits, primarily serving to store electrical charge, filter unwanted signal noise, decouple power supplies, and facilitate AC coupling between circuit stages. The MLCC category represents one of the most commonly used capacitor types in modern electronics due to their small physical footprint, excellent reliability, and cost-effectiveness at scale. The part designation indicates this is a radial-leaded capacitor housed in a cylindrical through-hole package format. This package style makes it well-suited for insertion into printed circuit boards during traditional wave soldering or hand assembly processes, particularly in applications where board real estate is moderately constrained but through-hole reliability is prioritized. The radial lead configuration allows straightforward PCB layout and is favored in many industrial and legacy equipment designs. Samsung's capacitor series offers consistent performance characteristics typical of general-purpose MLCCs, including good frequency response, low equivalent series resistance (ESR), and stable capacitance over reasonable operating temperature ranges. These capacitors are engineered to meet industry standards for reliability and longevity, making them suitable for both consumer-grade and industrial-grade applications. Engineers might specify the CL31C181JBNC when designing circuits that require a dependable ceramic capacitor in a traditional through-hole format rather than surface-mount alternatives. This choice is particularly relevant when PCB designs utilize existing through-hole assembly infrastructure, when hand assembly or repair is anticipated, or when the radial package simplifies mechanical mounting in confined spaces. The Samsung origin provides assurance of consistent manufacturing quality and straightforward availability through established electronic component distribution channels. This part is commonly found in applications including audio equipment, power supply filtering, signal conditioning circuits, legacy industrial control systems, and various general-purpose filtering and decoupling roles where moderate capacitance values are required. The combination of proven design, established manufacturing consistency, and broad compatibility with standard PCB assembly methods makes this capacitor a reliable choice for engineers designing equipment across multiple industrial sectors.
