CL43B105KBFNNNE

The CL43B105KBFNNNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for use in a wide range of electronic applications requiring reliable energy storage and signal coupling. As a ceramic capacitor, this component uses alternating layers of ceramic dielectric material and metal electrodes to achieve capacitance in a compact package format. This capacitor belongs to Samsung's established line of general-purpose MLCCs, which are widely deployed across consumer electronics, industrial control systems, telecommunications equipment, and automotive applications. The component features a surface-mount package configuration, making it suitable for automated assembly on printed circuit boards. Its small footprint and standardized package dimensions allow engineers to optimize board layouts while maintaining electrical performance and thermal management. MLCCs like this part are fundamental building blocks in modern electronics, commonly used for decoupling and bypass applications near integrated circuits, filtering in power supply circuits, timing applications, and signal coupling between circuit stages. Their widespread use stems from their reliability, cost-effectiveness, and consistent performance across temperature ranges typical in industrial and consumer environments. Engineers typically specify this particular part number when they require a capacitor that meets Samsung's quality standards and performance characteristics within their specific application constraints. Samsung MLCCs are recognized for consistent manufacturing quality and availability through established distribution channels, which is particularly valuable in industrial applications where supply chain reliability is critical. The ceramic dielectric composition ensures stable capacitance performance across typical operating conditions, and the surface-mount package facilitates high-volume manufacturing with modern assembly equipment. When selecting between capacitor alternatives, engineers consider factors such as capacitance value, voltage rating, package size, temperature stability, and equivalent series resistance (ESR). The CL43B105KBFNNNE designation indicates specific parameters within Samsung's product matrix that make it suitable for particular design requirements. Designers often cross-reference multiple capacitor options during the component selection process, but standardization on proven parts from established manufacturers like Samsung can reduce design risk and simplify procurement logistics. For applications requiring precise electrical specifications or environmental ratings, engineers should verify the component's detailed characteristics against their circuit requirements. This capacitor's continued availability through electronics distributors reflects its established use in numerous industrial and commercial applications, making it a practical choice for designs requiring reliable, proven component solutions.
