CL21B104KCFSFNG

The CL21B104KCFSFNG is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a reliable solution for general-purpose capacitive applications in consumer and industrial electronics. This component belongs to the CL series family, which is widely recognized in the industry for delivering consistent performance across diverse voltage and frequency ranges. Multilayer ceramic capacitors like this one are fundamental passive components used to store electrical charge and filter signals in electronic circuits. They serve multiple critical functions including power supply filtering, AC coupling and decoupling, noise suppression, and signal conditioning. The compact form factor and stable electrical characteristics of ceramic capacitors make them ideal for space-constrained applications where performance and reliability are equally important. The part designation CL21B104KCFSFNG indicates specific design parameters within Samsung's naming convention. The "CL21" prefix identifies this as part of the standard CL ceramic capacitor line, while the embedded codes reference the component's capacitance value, voltage rating, temperature coefficient, and packaging configuration. This particular model utilizes a surface-mount package format, which is the predominant standard for modern PCB assembly methods including automated pick-and-place manufacturing. Samsung's CL series capacitors are engineered for robustness across typical industrial operating temperature ranges, making them suitable for applications in consumer electronics, telecommunications equipment, automotive systems, industrial control circuits, and power conversion modules. The multilayer ceramic construction provides excellent volumetric efficiency, allowing manufacturers to achieve required capacitance values in minimal board space without sacrificing electrical performance or reliability. Engineers specify Samsung's CL series components for several key reasons. First, the brand reputation ensures consistent quality and long-term availability, which is critical for products requiring extended production runs or field service support. Second, Samsung maintains tight manufacturing tolerances across their ceramic capacitor lines, reducing circuit design margins and enabling more precise component selection. Third, the extensive range of capacitance values, voltage ratings, and temperature coefficients within the CL family allows designers to optimize part selection for specific circuit requirements rather than accepting generic substitutes. The multilayer ceramic construction also contributes to excellent frequency response characteristics, making these capacitors suitable for both DC filtering applications and higher-frequency signal processing tasks. This versatility, combined with Samsung's proven reliability track record and broad industrial adoption, makes the CL21B104KCFSFNG a sensible choice for design engineers seeking a dependable ceramic capacitor solution.
