CL21B104KBCNNWC

The CL21B104KBCNNWC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, part of the CL21 series. This component represents a widely-used option in the broader category of surface-mount ceramic capacitors, designed for general-purpose energy storage, filtering, and signal coupling applications across consumer and industrial electronics. Multilayer ceramic capacitors like the CL21B series function as passive components that store electrical energy in an electric field. They are essential building blocks in modern electronic circuits, serving multiple critical roles including power supply decoupling, noise filtering, AC coupling, and transient voltage suppression. The compact form factor of SMD MLLCs makes them ideal for high-density PCB layouts where space constraints are a primary concern. The CL21 family from Samsung is known for cost-effectiveness and reliable performance in mainstream applications. These capacitors use ceramic dielectric materials stacked in layers, which allows manufacturers to achieve significant capacitance values in relatively small physical packages. The part number designation indicates this is a standard performance-class component suitable for general industrial and consumer electronics rather than specialized high-reliability or extreme-environment applications. Common applications for capacitors in this series include switched-mode power supplies, audio amplifier circuits, microcontroller decoupling networks, LED driver circuits, telecommunications equipment, and various consumer appliances. Engineers frequently specify Samsung's CL21 series capacitors in designs where performance requirements are well-established and cost optimization is important without sacrificing basic reliability standards. Engineers might select the CL21B104KBCNNWC specifically when their circuit design calls for the exact capacitance value and voltage rating this part number represents, and when Samsung's manufacturing quality and availability are factors in their component selection process. The CL21 series benefits from established design histories across thousands of applications, making it a lower-risk choice compared to less common alternatives. Additionally, Samsung's scale of production for the CL21 family typically ensures consistent supply chains and competitive pricing in the market. For applications requiring extreme temperature ranges, exceptional frequency stability, or specialized dielectric properties, engineers would typically evaluate alternative capacitor families or manufacturers. However, for standard industrial control systems, power electronics, and consumer products operating under normal environmental conditions, the CL21B series provides a balanced combination of performance, availability, and economic value.
