CL21B104JBANNNC

The CL21B104JBANNNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, belonging to the CL21B series of general-purpose film and ceramic capacitors. This component is a surface-mount device designed for use in a wide range of industrial, consumer electronics, and embedded system applications where reliable energy storage and signal coupling are required. Multilayer ceramic capacitors like this part are fundamental passive components used extensively in power supply circuits, signal filtering, decoupling applications, and noise suppression throughout modern electronic equipment. Engineers specify MLCCs in audio amplifiers, switching power supplies, data acquisition systems, telecommunications infrastructure, automotive electronics, and industrial control boards. The CL21B series represents Samsung's established line of general-purpose ceramic capacitors intended for mainstream industrial and commercial applications rather than specialized high-performance or extreme-environment use cases. The designation "CL21B" indicates this capacitor follows Samsung's standard naming convention for medium-voltage, general-duty ceramic capacitors. The "104J" portion of the part number provides information regarding the component's capacitance value and voltage rating class. As a surface-mount component, this part is compatible with automated pick-and-place assembly processes and modern PCB manufacturing workflows, making it well-suited for high-volume production environments where consistency and manufacturability are critical. Engineers typically choose Samsung's CL21B series capacitors when they require a cost-effective, proven component with stable electrical characteristics across standard operating temperature ranges. The series is known for consistent performance in mainstream applications and represents a reliable middle ground between economy-grade capacitors and specialized high-performance alternatives. These components are widely stocked by distributors, ensuring supply chain predictability for manufacturers who need long-term availability. The CL21B series maintains consistent quality and performance standards suitable for applications where components must meet industrial reliability expectations without requiring premium-grade specifications. This makes the series popular in original equipment manufacturing (OEM) applications, contract manufacturing, and industrial equipment design where engineers need dependable, standard-grade passive components. When selecting this specific part number, engineers benefit from Samsung's reputation for manufacturing consistency, the widespread availability of the CL21B series across multiple suppliers, and compatibility with standard PCB assembly processes. The component integrates easily into bills of materials (BOMs) for equipment requiring general-purpose capacitor functions in compact surface-mount form factors.
