CL21A225KQFNNNG

The CL21A225KQFNNNG is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable passive component widely used across industrial electronics, consumer devices, and telecommunications equipment. This component belongs to the CL21 series, which is designed for general-purpose coupling, decoupling, and filtering applications in modern electronic circuits. Multilayer ceramic capacitors like this part function by storing electrical charge across multiple thin ceramic layers, enabling compact size with meaningful capacitance values. The CL21 series offers a practical balance between performance, size, and cost, making it suitable for high-volume manufacturing environments where space constraints and thermal stability are important considerations. The part number designation indicates this capacitor features a 1206 package size (according to imperial standard), one of the most common surface-mount component footprints in modern electronics assembly. This standardized form factor simplifies PCB layout, enables use with automated pick-and-place equipment, and maintains broad compatibility across different manufacturing facilities and design revisions. Typical applications for Samsung's CL21 series include power supply filtering in industrial control systems, signal conditioning circuits in measurement equipment, noise decoupling on microcontroller and processor supply rails, and impedance matching in RF and analog signal paths. These capacitors are frequently specified in automotive electronics, industrial automation controllers, LED lighting drivers, and various consumer electronics where reliable performance across operating temperature ranges is essential. Engineers typically specify MLCCs like the CL21A225KQFNNNG when they require a cost-effective, compact solution for non-critical filtering and coupling applications. Samsung's CL21 series has established a solid reputation for consistent manufacturing quality and reliable long-term performance in field applications. The series represents a mainstream choice rather than a specialized or premium option, making it well-suited for production designs where component availability and manufacturing continuity are practical concerns. The use of ceramic dielectric materials in this family provides adequate stability for most industrial and commercial-grade applications, though designers working with precision analog circuits or extreme environmental conditions may consider alternatives with different dielectric formulations or package options. When selecting this specific part, engineers benefit from its widespread availability through multiple distribution channels, established manufacturing support from Samsung, and compatibility with standard assembly processes used in contract manufacturing facilities worldwide. The CL21A225KQFNNNG represents a dependable choice for engineers building robust, maintainable industrial electronics.
