CL21B104KBFNNNG

The CL21B104KBFNNNG is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a standard component widely used in electronics manufacturing and industrial applications. This capacitor belongs to the CL21 series, which is designed for general-purpose energy storage, filtering, and signal coupling applications across consumer and industrial electronic equipment. Multilayer ceramic capacitors function as passive components that store electrical energy in an electric field, making them essential for power supply filtering, decoupling, noise suppression, and AC coupling in circuits. The CL21 series specifically targets applications requiring compact size with reliable performance across typical operating conditions. These capacitors are constructed using multiple layers of ceramic dielectric material with interleaved metal electrodes, allowing manufacturers to achieve useful capacitance values in a small physical footprint. The part number's nomenclature indicates this is a B-case package type capacitor, which offers a common balance between size and handling characteristics. This package format is particularly popular in high-volume manufacturing environments where automated assembly equipment is standard. The CL21B series is frequently specified for mainstream electronics manufacturing, including consumer appliances, industrial control systems, telecommunications equipment, and general-purpose power electronics. Samsung's CL21B capacitors are known for consistent quality and reliable performance in standard operating environments. Engineers typically specify these capacitors when they require a cost-effective, proven solution for general filtering and coupling applications where extreme performance characteristics are not necessary. The ceramic dielectric material provides stable performance across a reasonable temperature range, making these components suitable for most indoor electronic equipment operating at normal ambient conditions. When compared to alternative capacitor technologies, MLCCs offer distinct advantages including compact size, high volumetric efficiency, and excellent frequency response characteristics. The CL21B series strikes a practical balance between performance and cost, making it a popular choice for design teams seeking reliable, space-efficient solutions without premium pricing. These capacitors are also well-suited for applications where long-term availability and broad sourcing options are important considerations, as Samsung maintains strong production capacity for this series. The versatility of the CL21B series means these capacitors appear in diverse applications ranging from consumer electronics to industrial automation systems. Engineers select this specific part when they need a dependable general-purpose capacitor backed by a major manufacturer's quality standards and supply chain stability. For circuit designers working with standard operating parameters and conventional environmental conditions, the CL21B series represents a straightforward, proven component choice that simplifies procurement and manufacturing processes.
