CL31X476KQHNNNE

The CL31X476KQHNNNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung. This component belongs to the CL series, a widely-used family of general-purpose ceramic capacitors designed for applications requiring compact size, reliability, and cost-effectiveness across consumer electronics, industrial equipment, and telecommunications infrastructure. Multilayer ceramic capacitors are passive electrical components that store electrical energy in an electric field. They consist of alternating layers of ceramic dielectric material and metal electrodes, enabling high capacitance values in small physical packages. The CL31 designation indicates this particular capacitor uses a 1206 package size (3.2mm × 1.6mm), a standard form factor that balances ease of handling with practical space efficiency on printed circuit boards. This capacitor is commonly specified in power supply circuits, signal coupling and decoupling applications, filtering stages, and noise suppression across various industrial and consumer applications. Engineers frequently encounter CL series capacitors in analog and digital circuits where stable, predictable capacitance over operating life is required. The 1206 package size makes this component suitable for both automated surface mount assembly and manual rework scenarios, offering practical manufacturability advantages. The "X" designation in the part number indicates the voltage rating class, while other nomenclature elements specify dielectric type and performance characteristics within Samsung's CL family. These capacitors typically exhibit stable electrical behavior across typical operating temperature ranges and offer good frequency response characteristics suitable for both low-frequency filtering and higher-frequency decoupling applications. Engineers typically specify exact CL series part numbers like this one when they require components with Samsung's specific quality standards, documented reliability data, and proven supply chain availability. The MLCC market offers numerous alternatives from other manufacturers, but specifying a particular manufacturer and part number ensures consistency in performance, manufacturing processes, and long-term product support. Industrial applications often require this level of specification certainty for reproducibility and maintenance purposes. The 1206 package size represents an optimal balance for many applications, offering sufficient lead spacing for typical PCB trace widths while maintaining reasonable component density. This makes it a preferred choice for designers balancing performance requirements with practical production constraints. Samsung's CL series maintains a strong reputation for consistency and reliability in industrial applications, contributing to its widespread adoption across multiple market segments.
