CL21B105KOF4PNE

# CL21B105KOF4PNE Product Description The CL21B105KOF4PNE is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for use in a wide range of electronic applications requiring reliable energy storage and filtering. This component belongs to the CL series family of ceramic capacitors, which are widely recognized in the electronics industry for consistent performance and dependable operation across diverse temperature and voltage conditions. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronics. They serve critical functions including power supply filtering, signal coupling and decoupling, high-frequency noise suppression, and timing circuit applications. The MLCC technology allows for compact form factors while maintaining stable capacitance values, making these components ideal for space-constrained designs where engineers need to maximize circuit density without sacrificing electrical performance. The CL21 designation indicates this is a surface-mount device in a 0805 package size, one of the most popular standardized form factors in contemporary PCB design. The 0805 package offers a practical balance between handling ease during assembly and component miniaturization, making it suitable for both high-volume manufacturing and prototype development environments. This standardized package size means the part integrates seamlessly with automated pick-and-place assembly equipment commonly used in manufacturing facilities worldwide. Samsung's CL series capacitors are engineered to deliver stable performance across extended operating temperature ranges typical in industrial and consumer applications. The ceramic dielectric material provides excellent frequency response characteristics, making these capacitors particularly useful in RF circuits, power management systems, and digital logic applications where high-frequency performance matters. Engineers typically specify Samsung CL series capacitors when they require proven reliability, consistent electrical characteristics across production batches, and compatibility with standard PCB assembly processes. The widespread availability of this part family makes it a practical choice for designs that need long-term supply security and second-source flexibility. Additionally, Samsung's manufacturing capabilities ensure tight quality control and traceability for applications where component reliability documentation is important. The CL21B105KOF4PNE would be selected in applications ranging from consumer electronics and industrial control systems to automotive electronics and communications equipment. Its compact size, proven performance characteristics, and established supply chain make it a sensible choice for design engineers looking to balance performance requirements with cost-effectiveness and manufacturing simplicity in their circuit designs.
