CL21B105KAFNFNE

The CL21B105KAFNFNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, belonging to the CL21 series of general-purpose film and ceramic capacitors. This component is designed for use in a broad range of electronic applications where compact size, reliability, and cost-effectiveness are important factors. Multilayer ceramic capacitors like this model are among the most widely used passive components in modern electronics. They function to store electrical energy, filter signals, decouple power supplies, and stabilize voltage in circuits. The CL21 series represents Samsung's mainstream offering for industrial and consumer electronics, where performance demands are moderate to standard and space constraints are typical but not extreme. The designation in this part number indicates specific characteristics of the component. The "CL21" prefix denotes the physical package size and form factor—a compact surface-mount device suitable for automated assembly on printed circuit boards. The "B" designation points to particular electrical specifications within Samsung's classification system. This series is commonly found in power supply circuits, audio equipment, telecommunications infrastructure, automotive electronics, industrial control systems, and general-purpose consumer electronics where stable capacitance and acceptable frequency response are needed. Engineers typically specify components from the CL21 series when design priorities include board space optimization, high-volume manufacturing economics, and proven reliability in non-critical filtering or bypass applications. These capacitors offer adequate performance for mainstream industrial use without the premium cost of specialized high-frequency, high-temperature, or ultra-high-reliability variants. They integrate well into standard PCB layouts and are compatible with conventional reflow soldering processes. Samsung's CL21 series capacitors are manufactured using multilayer ceramic technology, which provides stable capacitance across moderate temperature ranges and reasonable frequency response for standard applications. The series has an established track record across decades of deployment in millions of devices, making it a trusted choice for engineers seeking components with predictable behavior and minimal field failure rates in normal operating conditions. This part would typically be selected over specialized alternatives when the application does not require extreme temperature stability, ultra-high frequency performance, or exceptional reliability ratings. It represents practical engineering—delivering necessary performance at reasonable cost with the assurance of established quality and widespread industry acceptance. For engineers designing production equipment, consumer devices, or industrial systems with conventional electrical requirements, the CL21B105KAFNFNE offers a straightforward, proven component choice.
