CL21B102KC6WPNC

The CL21B102KC6WPNC is a multilayer ceramic capacitor (MLCC) manufactured by Samsung, designed for use in electronic circuits where stable capacitance and compact form factor are essential. This component belongs to the CL series of film and ceramic capacitors, representing a standard industrial-grade solution widely integrated into consumer electronics, telecommunications equipment, automotive systems, and industrial control applications. Multilayer ceramic capacitors function as energy storage and filtering elements in circuits, smoothing voltage fluctuations, decoupling power supply noise, and enabling signal coupling or blocking in AC applications. The CL21 series specifically indicates a package designation suited for surface-mount assembly, allowing automated production processes and high-density PCB layouts—a key advantage in modern electronics manufacturing where board space is limited and production efficiency is critical. The part designation suggests this capacitor operates within Samsung's general performance class for commercial and industrial applications. Devices in this series are typically chosen by design engineers for their reliability, consistent electrical characteristics across temperature ranges, and proven performance in mainstream circuit topologies. Samsung's manufacturing quality and widespread availability make these components a trusted specification for applications where long-term stability and supply chain dependability matter. Engineers might specify the CL21B102KC6WPNC over alternative capacitors for several practical reasons. First, Samsung MLCCs maintain well-established compatibility with standard reflow soldering processes and existing PCB design templates, reducing redesign costs when upgrading product generations. Second, this part's position within a standardized series means it has been validated across numerous production runs and end-use environments, providing predictable field performance. Third, the compact package enables designers to meet shrinking form-factor requirements without sacrificing circuit performance or introducing design complexity. This capacitor is particularly valuable in power distribution networks, where it removes high-frequency switching noise from digital logic circuits and microprocessors. It's also commonly found in analog signal conditioning circuits, where stable capacitance prevents distortion. Industrial applications such as motor drives, power conversion systems, and instrumentation regularly incorporate components from this family due to their proven robustness under sustained operating conditions. For engineers evaluating capacitor options, the CL21B102KC6WPNC represents a mature, well-documented solution that balances performance, cost-effectiveness, and manufacturing convenience. Its presence in established supply chains and compatibility with standard assembly processes make it a practical specification for both new designs and legacy product support situations where component continuity is important.
