CL21B104KCFSFNE

The CL21B104KCFSFNE is a multilayer ceramic chip capacitor manufactured by Samsung, representing a reliable component choice for general-purpose filtering and coupling applications across industrial and consumer electronics. This surface-mount capacitor belongs to Samsung's established CL series family, known for consistent performance and broad availability in global supply chains. Multilayer ceramic capacitors (MLCCs) like this part are fundamental building blocks in modern electronic circuits. They function as energy storage and filtering elements, smoothing voltage fluctuations, decoupling power supplies, and blocking DC while passing AC signals. Engineers specify ceramic capacitors in thousands of locations across a typical circuit board, making component selection critical for both performance and cost management. The part's designation indicates it uses a standard rectangular surface-mount package suitable for automated assembly processes. This package type enables high-density PCB layouts while maintaining compatibility with standard pick-and-place equipment used in manufacturing environments. The small footprint makes it particularly valuable in space-constrained applications where board real estate is at a premium. Samsung's CL21B series occupies the mid-range segment of ceramic capacitor offerings. Components in this family are commonly selected for general industrial applications, power management circuits, signal conditioning, and noise suppression where premium performance characteristics are not strictly required but reliability and cost-effectiveness matter significantly. The series has proven track record in telecommunications infrastructure, industrial control systems, automotive electronics, and consumer appliances. Engineers might specify this exact part number over alternatives for several reasons. First, the established design history of the CL21B family reduces qualification risk for new products. Second, Samsung's manufacturing scale ensures reasonable lead times and pricing compared to boutique component suppliers. Third, the standardized package and electrical profile make this part a straightforward replacement in existing designs, supporting product lifecycle continuity and manufacturing efficiency. The multilayer construction of ceramic capacitors provides stable performance across varying environmental conditions, making them suitable for both consumer-grade and industrial-temperature applications. This inherent reliability, combined with Samsung's quality standards, supports use in equipment requiring long service life and minimal maintenance. When evaluating this component, engineers should confirm that the specific voltage rating, capacitance value, and temperature characteristics match their circuit requirements by consulting the manufacturer's full technical documentation. The part's suitability depends on precise electrical specifications and application context, which vary significantly across different industrial and commercial use cases.
