CL43B105KBJNNNF

The CL43B105KBJNNNF is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, representing a workhorse component found in countless electronic applications across industrial, consumer, and telecommunications equipment. This capacitor belongs to the CL series family, which is widely recognized for delivering reliable performance in demanding environments where consistent electrical characteristics are required. Multilayer ceramic capacitors are fundamental passive components used to store electrical charge, filter signals, decouple power supplies, and stabilize voltage across circuits. The CL43B format indicates this is a surface-mount device, allowing for compact board layouts and automated assembly in modern manufacturing processes. These capacitors are built using multiple alternating layers of ceramic dielectric material and metallic electrodes, a construction method that enables high capacitance values in relatively small physical packages while maintaining good electrical performance across frequency ranges. The "105K" designation within the part number indicates the capacitance value and tolerance class of this component. Samsung's CL series MLCCs are engineered to meet the needs of engineers designing equipment that requires stable capacitive performance without excessive drift or failure risk. These capacitors are commonly specified in power supply circuits, signal conditioning applications, frequency compensation networks, and general decoupling applications where the moderate voltage and temperature stability of standard ceramic dielectrics is sufficient. Engineers typically select this specific part number when designing circuits requiring a particular capacitance value in a proven, readily available package from a trusted manufacturer. Samsung's CL series has established a strong reputation in industrial applications due to consistent manufacturing quality and availability through distribution networks. The surface-mount design makes this component ideal for high-density PCB layouts where space constraints are a concern, and where automated pick-and-place assembly is standard practice. This capacitor would be found in applications ranging from industrial control systems and power conversion equipment to consumer electronics and networking hardware. The ceramic dielectric formulation used in this series provides the reliability needed for applications operating across moderate temperature ranges, making it suitable for both commercial and industrial operating environments. When specifying the CL43B105KBJNNNF, design engineers benefit from the combination of proven performance characteristics, broad availability, and the established track record of Samsung's capacitor manufacturing. This makes it a practical choice for production designs requiring dependable passive components without unnecessary premium specifications.
