CL31C221JBCNNNC

The CL31C221JBCNNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a widely-used component in modern electronics manufacturing. This capacitor belongs to the CL series family, which is engineered for general-purpose decoupling, filtering, and energy storage applications across consumer, industrial, and telecommunications equipment. Multilayer ceramic capacitors like this part are fundamental building blocks in circuit design, serving critical functions in power supply circuits, signal filtering, and noise suppression. Their compact form factor and reliable performance make them essential in nearly every category of electronic equipment, from portable consumer devices to industrial control systems and automotive electronics. The CL31C221JBCNNNC uses a ceramic dielectric technology, which provides several advantages for engineers specifying components. Ceramic capacitors offer stable performance across temperature ranges typical of industrial environments, good frequency response characteristics, and excellent reliability when properly applied. The MLCC construction allows for miniaturization while maintaining adequate capacitance values and voltage ratings, which is particularly valuable in space-constrained applications. Samsung's CL series capacitors are recognized for consistent quality and availability through established distribution channels, making them a practical choice for manufacturers seeking reliable long-term sourcing. The standardized design and proven performance history of this series reduce design risk compared to lesser-known alternatives. Engineers typically specify this particular part number when their circuit design calls for a ceramic capacitor in the package size and electrical rating range that this component provides. The specific suffix codes in the part number indicate particular characteristics related to packaging, capacitance value, voltage rating, and temperature characteristics. These precision designations ensure that replacement parts or procurement from different sources maintain compatibility with the original design intent. This capacitor would be appropriate for applications including switching power supplies, voltage regulation circuits, high-frequency filtering in communication equipment, and general decoupling near integrated circuits. Its ceramic construction makes it suitable for applications where cost-effectiveness and compact placement are important, though designers must account for ceramic capacitors' capacitance variation characteristics across temperature and voltage ranges when sizing for critical applications. Typical industrial users of Samsung's CL series capacitors include power electronics manufacturers, telecommunications equipment builders, industrial automation suppliers, and contract electronics manufacturers. The combination of Samsung's manufacturing reputation, the proven design of the CL series, and the standardized performance of ceramic MLLCs makes this component a dependable choice for volume production and long-term field deployment.
