CL21B102JBANNNC

The CL21B102JBANNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a robust component choice for general-purpose filtering, coupling, and bypass applications across industrial and consumer electronics. This capacitor belongs to the CL21 series, which is widely recognized in the electronics industry for reliable performance in mainstream applications. Multilayer ceramic capacitors like this component consist of alternating layers of ceramic dielectric material and metal electrodes, allowing manufacturers to achieve significant capacitance values in compact packages. The CL21 series typically utilizes a 1206 surface-mount package format, making it compatible with standard automated assembly processes and providing a good balance between component size and ease of handling during manufacturing and rework operations. The "J" designation in the part number indicates the capacitance tolerance classification for this device. Samsung's CL21 series capacitors are designed to meet the performance requirements of cost-conscious applications where high precision is not critical, making them ideal for decoupling power supplies, signal coupling between circuit stages, and general filtering duties. The "BANNNC" suffix provides additional specification details regarding the voltage rating, packaging, and internal construction characteristics specific to this exact configuration. Engineers typically specify ceramic capacitors from established manufacturers like Samsung when they require proven reliability, consistent performance across temperature variations, and availability from multiple distribution channels. The CL21 series benefits from decades of design refinement, resulting in predictable behavior in real-world circuit implementations. These capacitors are particularly common in industrial control systems, power management circuits, consumer appliances, and general-purpose PCB designs where performance requirements do not demand premium specifications. One key advantage of selecting a mainstream part like the CL21B102JBANNNC is design flexibility. The widespread adoption of this series means numerous reference designs exist in technical literature, and compatibility with standard reflow soldering processes is well-established. Additionally, the mature product line typically offers stable pricing and consistent availability compared to specialized alternatives. Applications for this capacitor range from voltage regulation circuits and switching power supplies to audio signal processing and sensor interface circuits. Its mid-range performance class positions it as a workhorse component for engineers balancing performance requirements, cost constraints, and production volume considerations. Whether used as a primary decoupling element or as part of a multi-stage filtering network, the CL21B102JBANNNC delivers the stable, predictable performance that industrial applications demand.
