CL10B121KB8NNNC

The CL10B121KB8NNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for general-purpose filtering, decoupling, and coupling applications across a broad range of electronic equipment and industrial systems. This component belongs to Samsung's established MLCC product family and is housed in a 1206 surface-mount package, which is one of the most commonly specified sizes in modern electronics manufacturing due to its balance of compact footprint and reasonable handling characteristics for automated assembly. MLCCs are fundamental passive components used in virtually every category of electronic device. The 1206 package size makes this particular part suitable for applications where board space is moderately constrained but where the designer needs adequate component size for reliable soldering and mechanical stability. This capacitor would typically be found in power supply circuits, high-frequency signal processing stages, impedance matching networks, and noise suppression applications across consumer electronics, industrial control systems, telecommunications equipment, and automotive electronics. The "B" designation in Samsung's naming convention indicates this capacitor operates within a specific temperature coefficient range, making it appropriate for applications requiring stable performance across normal operating temperature variations. The X7R or similar dielectric material classification common to this series provides relatively flat capacitance characteristics across both temperature and voltage ranges, which is important for circuits where capacitive values must remain predictable during thermal cycling or under varying electrical stress. Designers often specify this particular part number when they require a cost-effective, readily available capacitor with proven reliability in high-volume production environments. Samsung's MLCC products benefit from extensive validation in industrial applications and established supply chain relationships. The 1206 package strikes a practical middle ground: larger than 0603 packages, offering better performance margins, but smaller than 1210 or larger packages, helping minimize PCB real estate consumption. When evaluating this part against alternatives, engineers consider factors such as the established second-sourcing availability of the 1206 package size, Samsung's manufacturing consistency, and the well-documented thermal and electrical performance of this MLCC family. For applications requiring standard capacitance values in non-specialized filtering or coupling roles, the CL10B121KB8NNNC represents a standard specification choice that balances performance requirements with manufacturing efficiency and cost management across production volumes. This component is appropriate for OEM manufacturers, contract electronics assemblers, and systems integrators working across industrial, commercial, and consumer product segments.
