CL21B103KCANNNL

The CL21B103KCANNNL is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable passive component widely used in electronic equipment across industrial and consumer applications. This capacitor belongs to Samsung's CL21 series, which is engineered to deliver consistent performance in compact form factors suitable for modern PCB designs with space constraints. Multilayer ceramic capacitors like this component function as energy storage and filtering elements within circuits. They are used to smooth voltage fluctuations, filter high-frequency noise, decouple power supplies, and support signal coupling and decoupling operations. These applications make MLCCs essential in virtually every electronic system, from industrial control boards and power supplies to telecommunications equipment and automotive electronics. The CL21 series designation indicates this is a general-purpose MLCC designed for mainstream industrial and commercial applications rather than specialized military or high-reliability segments. Capacitors in this series are commonly found in consumer electronics, industrial measurement equipment, LED drivers, switching power supplies, and general-purpose computing applications. The compact chip form factor typical of the CL21 family makes these capacitors suitable for density-optimized circuit designs where board space is at a premium. Samsung's CL21 series capacitors are recognized for consistent dielectric properties and stable performance across standard operating temperature ranges. They are manufactured using multilayer ceramic technology, which provides good volumetric efficiency—delivering usable capacitance in a small physical package. This makes them cost-effective for high-volume production applications where component miniaturization and manufacturing reliability matter. Engineers typically specify components from the CL21 series when designing applications that require dependable, commercially-rated capacitors without specialized environmental ratings or exotic performance characteristics. The series offers a good balance between performance, cost, and availability. These capacitors are well-established in the market with extensive production volume, which generally ensures consistent supply and competitive pricing compared to specialized alternatives. The part's nomenclature indicates specific design parameters that determine its electrical behavior, including its capacitance value, voltage rating, and tolerance class. Designers select exact part numbers from the CL21 family based on the specific decoupling, filtering, or coupling requirements of their circuit topology. For applications requiring detailed electrical characteristics, capacitance values, or operating temperature specifications for this exact part number, consulting Samsung's published datasheets and technical documentation is recommended, as these specifications vary within the product family.
