CL21B105KAF4PNE

The CL21B105KAF4PNE is a ceramic capacitor manufactured by Samsung, representing a reliable component choice for general-purpose filtering and coupling applications across industrial and consumer electronics. This part belongs to the CL21 series, which is widely recognized in the electronics industry for consistent performance and broad availability in standard voltage and capacitance ranges. As a ceramic capacitor, this component functions as an energy storage and filtering element in electronic circuits. Ceramic capacitors are fundamental building blocks in power supply circuits, signal filtering networks, decoupling applications, and AC coupling stages. They are preferred in many designs due to their compact size, low cost, and ability to handle moderate frequency ranges effectively. The CL21 series specifically caters to applications requiring general-purpose capacitance without the size constraints of larger component packages. The physical form factor of the CL21 series uses a standard surface-mount package, making it suitable for automated assembly processes common in modern manufacturing environments. This package type enables high-density circuit board layouts, which is particularly valuable in space-constrained applications such as portable instruments, control modules, and embedded systems. The standardized dimensions and mounting compatibility with industry-standard pick-and-place equipment reduce assembly costs and production complexity. Engineers typically specify Samsung's CL21 series ceramics when designing cost-sensitive applications that don't demand specialized high-performance characteristics. These capacitors work well in non-critical filtering roles, local decoupling near integrated circuits, timing circuit applications, and general signal conditioning. The series provides adequate performance stability across typical industrial operating temperatures, making it suitable for equipment that functions in standard environmental conditions. Compared to alternative capacitor technologies, ceramic capacitors like the CL21B105KAF4PNE offer advantages in miniaturization and cost-effectiveness. While film capacitors might provide superior performance in certain audio or precision applications, and electrolytic capacitors handle higher capacitance values, the ceramic solution strikes an effective balance for mainstream industrial electronics. Samsung's manufacturing reputation supports consistent quality and availability, reducing design risk when incorporating this part into production. This component is commonly encountered in consumer appliances, industrial control systems, telecommunications equipment, and automotive electronics where standard performance specifications satisfy application requirements. The widespread use of the CL21 series across diverse industries reflects its proven reliability and suitability for general engineering applications requiring straightforward capacitive functionality in an economical, compact format.
