CL31C221JGFNNWE

The CL31C221JGFNNWE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable solution for general-purpose energy storage and filtering applications across industrial and consumer electronics. This component belongs to Samsung's established ceramic capacitor family, designed to meet the needs of engineers requiring proven performance in compact form factors. Multilayer ceramic capacitors like this part function as energy storage devices in electronic circuits, smoothing power supply ripple, decoupling noise from signal lines, and providing localized energy buffering near active components. The MLCC technology offers significant advantages over alternative capacitor types, including a small physical footprint, excellent high-frequency performance, and cost-effectiveness at volume production scales. The designation "CL31" in the part number identifies this as belonging to Samsung's standard MLCC series, which emphasizes reliability and consistent performance across commercial and industrial temperature ranges. The suffix nomenclature indicates this specific variant is packaged in a conventional surface-mount format optimized for automated assembly processes, making it ideal for modern PCB manufacturing workflows. The compact package size enables dense component placement on circuit boards, which is particularly valuable in space-constrained applications such as portable instrumentation, embedded control systems, telecommunications equipment, and power management modules. Engineers typically specify ceramic capacitors like the CL31C221JGFNNWE in applications where stability, miniaturization, and cost efficiency are priorities. This component is particularly well-suited to bypass and decoupling roles in digital logic circuits, analog signal conditioning stages, and switching power supply designs. The ceramic dielectric material provides stable capacitance across moderate temperature variations, and the MLCC construction eliminates many reliability concerns associated with electrolytic alternatives, such as leakage current degradation and limited shelf life. Compared to alternative solutions, this Samsung MLCC offers the combination of established manufacturing processes, documented supply chain reliability, and performance consistency that industrial buyers require. Where circuit designers need straightforward capacitive functionality without specialized requirements like extreme temperature operation or unusually high voltage ratings, this component provides a straightforward specification path that balances performance, cost, and availability. The part's identification through this specific part number ensures traceability and consistency in production environments where component standardization is important for quality control and regulatory compliance.
