CL43B223KIJNNWE

The CL43B223KIJNNWE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for use in a wide range of industrial and consumer electronic applications. This component belongs to Samsung's established line of general-purpose ceramic capacitors and represents a reliable choice for engineers seeking proven performance in standard circuit designs. Multilayer ceramic capacitors are fundamental passive components used extensively across modern electronics for energy storage, signal filtering, power supply decoupling, and noise suppression. The CL43B series specifically targets applications where consistent performance, compact size, and cost-effectiveness are valued. These capacitors are constructed from multiple layers of ceramic dielectric material with alternating metal electrodes, allowing significant capacitance to be achieved in a physically small footprint. The "B" designation in this part number indicates the case size category, placing this component in a common form factor suitable for both through-hole and surface-mount circuit board designs, depending on the specific variant configuration. Samsung's manufacturing processes ensure reliable operation across typical industrial temperature ranges, making these capacitors appropriate for equipment operating in controlled to moderately variable environmental conditions. Engineers typically specify this part for general-purpose decoupling applications in power distribution networks, where capacitors work to maintain stable voltage levels and reduce noise on supply rails. The CL43B series is also commonly found in signal conditioning circuits, timing applications, and coupling stages where DC blocking with AC signal transmission is required. The robust construction and proven track record of Samsung's ceramic capacitors make them suitable specifications for designs targeting both high-volume production and specialized industrial equipment. Compared to alternatives, this specific part number offers the balance of characteristics typical to Samsung's mainstream capacitor offerings: established supply chain presence, proven field reliability, and competitive performance for applications not requiring specialized extreme-temperature or high-voltage ratings. Engineers working on designs requiring exact electrical specifications, extended temperature ranges, or unusual voltage ratings would typically evaluate capacitors from other series within the CL product family or from competing manufacturers. The MLCC category itself remains one of the most widely deployed passive component families in electronics manufacturing, present in virtually all modern electronic devices from consumer goods to industrial control systems. Selecting a recognized manufacturer like Samsung for standard applications helps ensure design continuity and reduces supply chain risk compared to lesser-known alternatives.
