CL31C221JHFNNNF

The CL31C221JHFNNNF is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a widely used passive component in modern electronics. This capacitor belongs to the CL31 series, which is designed for general-purpose applications across consumer, industrial, and commercial electronics. Multilayer ceramic capacitors function as energy storage devices that block direct current while allowing alternating current to pass. They are fundamental building blocks in power supply circuits, signal filtering, decoupling, and noise suppression applications. The CL31 series specifically targets applications requiring compact size with reliable performance, making these capacitors essential in space-constrained PCB designs. The part designation indicates this capacitor uses a standard surface-mount package format suitable for automated assembly processes. Samsung's CL31 series is known for consistent quality and availability across the electronics supply chain, making it a preferred choice for engineers designing production-run equipment rather than experimental prototypes. These capacitors are commonly found in power management circuits, audio equipment, telecommunications infrastructure, industrial control systems, and various consumer electronics requiring stable capacitive filtering. Engineers typically specify Samsung MLCCs for several reasons. First, Samsung maintains strict manufacturing controls and reliability standards, ensuring consistent performance across production batches. Second, the CL31 series offers a proven track record in field applications, reducing design risk. Third, Samsung's global manufacturing capacity generally provides better availability and shorter lead times compared to some specialty component suppliers. Fourth, these capacitors demonstrate reliable performance across typical operating temperature ranges found in industrial environments. The multilayer construction of this component provides several advantages over older thin-film or electrolytic alternatives. MLCCs offer higher capacitance density in smaller packages, better frequency response characteristics, excellent reliability with no electrolyte to dry out, and superior performance in high-temperature applications. The ceramic dielectric material used in the CL31 series provides stable capacitance characteristics, making it suitable for precision filtering and timing circuits. When selecting the CL31C221JHFNNNF specifically, engineers benefit from Samsung's extensive documentation and application notes available through standard industrial component channels. The part's long-term availability and consistent specifications make it suitable for designs with extended production lifespans, where component continuity is critical. This capacitor is commonly paired with other passive and active components in signal conditioning circuits, voltage regulator modules, and EMI suppression networks. Its proven performance in diverse industrial applications makes it a reliable choice for engineers prioritizing dependability and manufacturability in their designs.
